Important Safety Information

Anhydrous Ammonia Safety

The NP4000A Nutri-Pro® applicator includes several manuals in addition to this Operator manual that contain crucial safety information:

• 407-551M Using Anhydrous Ammonia Safely

• 016-0159-403 Raven AccuFlow™ Operator manual

• 016-0159-831 Raven SCS 450 Installation, Operation and Service manual

• FVC062 Squibb-Taylor Flo-Max™ manual (breakaway coupler)

Read all of these manuals. If you do not have the current edition of one or more, contact Great Plains for a replacement copy.

EPA EHS (Extremely Hazardous Substance):

Despite the common odor, anhydrous ammonia properties are dramatically different from those of household ammonia cleaning solutions (dilute ammonium hydroxide). An uncontrolled release of NH3 anhydrous ammonia can easily be fatal or cause permanent disabling injury.

If you are new to NH3 operations, study everything you can about this chemical and how to use it safely.

Suffocation, Blinding, Burning, Freezing, Disabling and Disﬁgurement Hazards:

Your life and health, the lives and health of your workers and community, the continued commercial availability of anhydrous ammonia, and continuation of agricultural NH3 transport exceptions depend on you conducting meticulously careful operations.

Read All Manuals

The Anhydrous Safety manual (407-551M), this manual, the meter manual and the breakaway coupler manual (FVC062) are required reading for safe operations. All operators of this equipment must read these manuals.

Even if you are an experienced anhydrous ammonia operator, read the “Using Anhydrous Ammonia Safely” manual (407-551M).

The diamond icons and decal image above appear in this manual whenever a topic deals with anhydrous ammonia safety. See the “Using Anhydrous Ammonia Safely” manual (407-551M) for details on these signs. These topics do not apply to NP4000 models conﬁgured only for conventional liquid fertilizer.

Look for Safety Symbol

The SAFETY ALERT SYMBOL indicates there is a potential hazard to personal safety involved and extra safety precaution must be taken. When you see this symbol, be alert and carefully read the message that follows it. In addition to design and conﬁguration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

Be Aware of Signal Words

Signal words designate a degree or level of hazard seriousness.

DANGER, and the color Safety Red, indicate an imminent hazard which, if not avoided, will result in death or serious injury. This signal word is limited to the most extreme situations, typically for machine components that, for functional purposes, cannot be guarded.

WARNING, and the color Safety Orange, indicate a potential hazard which, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.

CAUTION, and the color Safety Yellow, indicate a potential hazard which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

Prepare for Emergencies

▲ Be prepared if a ﬁre starts.

▲ Keep a ﬁrst aid kit and ﬁre extinguisher handy.

▲ Keep emergency numbers for doctor, ambulance, hospital

and ﬁre department near phone. Know the reporting requirement for spills or releases of the chemicals you are using. Have contact numbers available.

▲ For anhydrous ammonia operations, have additional

contact information for:

• national response center

• regional (state) response center

• local response center

▲ If a ﬁre threatens an anhydrous ammonia tank, evacuate the

area. The tank may heat up faster than the relief valve can vent the rising pressure, resulting in a catastrophic gas release and possibly an explosion.

417-199M Table of Contents Index 2014-05-14

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3

Be Familiar with Safety Decals

▲ Read and understand “Safety Decals” on page 9,

thoroughly.

▲ Read all instructions noted on the decals.

▲ Keep decals clean. Replace damaged, faded and illegible

decals.

Wear Protective Equipment (PPE)

▲ Wear clothing and equipment appropriate for the job. Avoid

loose-ﬁtting clothing.

▲ Waterproof, wide-brimmed hat

▲ Face shield, goggles or full face respirator.

▲ Prolonged exposure to loud noise can cause hearing

impairment or loss. Wear suitable hearing protection such as earmuffs or earplugs.

▲ Avoid wearing entertainment headphones while operating

machinery. Operating equipment safely requires the full attention of the operator.

▲ See manual 407-551M for speciﬁc requirements and

recommendations for NH3 PPE.

▲ Goggles with side shields or a full face respirator are

required if handling or applying dusts, wettable powders, or granules or if being exposed to spray mist.

▲ Cartridge-type respirator approved for pesticide vapors

unless conventional liquid fertilize label speciﬁes another type of respirator.

▲ Waterproof, unlined gloves. Neoprene is recommended.

▲ Cloth coveralls/outer clothing changed daily; waterproof

items if there is a chance of becoming wet with spray.

▲ Waterproof apron

▲ Waterproof boots or foot coverings

▲ Do not wear contaminated clothing. Wash protective

clothing and equipment with soap and water after each use. Personal clothing must be laundered separately from household articles.

▲ Clothing contaminated with certain pesticides must be

destroyed according to state and local regulations. Read chemical label for speciﬁc instructions.

Use Safety Chains

(For all nurse tanks)

▲ Use chain with a strength rating equal to or greater than

the gross weight of towed machinery.

▲ Attach nurse tank chain(s) to anchors provided on

applicator. Allow only enough slack in chain for turns.

▲ Replace chain if any links or end ﬁttings are broken,

stretched or damaged.

▲ Do not use safety chain for towing.

▲ Current regulations require two chains on anhydrous

ammonia nurse tank carts.

Avoid High Pressure Fluids

Escaping ﬂuid under pressure can penetrate the skin, causing serious injury. This fertilizer applicator requires a Power-Beyond port, which is always under pressure when the tractor is running.

▲ Avoid the hazard by relieving pressure before disconnecting

hydraulic lines.

▲ Use a piece of paper or cardboard, NOT BODY PARTS, to

check for suspected leaks.

▲ Wear protective gloves and safety glasses or goggles when

working with hydraulic systems.

▲ If an accident occurs, seek immediate medical attention

from a physician familiar with this type of injury.

Minimize Radiation Exposure

The optional DICKEY-john® RVS II and RVS III Radars are intentional radiators of RF energy. Although its radiated energy level is far below the limits set by EN 61010-1:1993 A2:1995-Chapter 12.4, it is advisable not to look directly into the face of the unit.

The radar must radiate toward the ground and at least 20 cm (8 inches) away from a human during use to comply with the RF human exposure limits as called out in FCC 47 CFR Sec.2.1091. DO NOT RE-MOUNT OR USE THE RADAR IN A MANNER INCONSISTENT WITH ITS DEFINED USE.

Keep Riders Off Machinery

Riders obstruct the operator’s view. Riders could be struck by foreign objects or thrown from the machine.

▲ Never allow children to operate equipment.

▲ Keep all bystanders away from machine during operation.

417-199M Table of Contents Index 2014-05-14

Page 9

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 5

Use Safety Lights and Devices

Slow-moving tractors and towed applicators can create a hazard when driven on public roads. They are difﬁcult to see, especially at night.

▲ Use ﬂashing warning lights and turn signals whenever

driving on public roads.

▲ Use lights and devices provided with applicator.

Tires Not a Step

Do not use gauge wheel or lift-assist tires as steps. A tire could spin underfoot, resulting in a fall onto the applicator or ground, possibly causing serious injury.

▲ The gauge wheel tires can be in poor ground contact at any

time, even with the fertilizer applicator lowered in the ﬁeld. They can appear to be in ground contact, and spin easily, in multiple conditions.

▲ The lift-assist tires can be in poor ground contact, or out of

ground contact, whenever the fertilizer applicator is lowered.

Remain Clear of Overhead Lines

▲ If the fertilizer applicator contacts a power line, lethal

voltage may be present on all metal parts. At higher voltage, the applicator does not need to be in line contact for the hazard to exist. Maintain at least 10 foot (3 m) clearance.

▲ Electrocution can occur without direct contact between the

energized fertilizer applicator and a person near the fertilizer applicator.

▲ Watch for sagging, damaged or low electrical lines. The

folded fertilizer applicator could contact lines lower than 13 foot (4 m). Overhead lines at farm structures are a particular hazard. An incorrectly folded applicator is at risk from lines lower than 22 foot (7 m).

▲ Watch for all electrical lines during folding and unfolding

operations. Use a spotter during folding and unfolding. Know the location and height of all lines during transport and in ﬁelds.

▲ If an electrical hazard is observed while on the ground near

the applicator, hop at least 100 feet (30 m) away with both feet together and summon professional help. At higher voltage, lethal voltage gradients can also be present at the soil surface.

▲ Consult your tractor manual for advice on how to respond

to an electrical hazard event while in the cab.

Transport Machinery Safely

Maximum transport speed for applicator is 20 mph (32 kph), 13 mph (22 kph) in turns. Some rough terrains require a slower speed. Sudden braking can cause a towed load to swerve and upset.

▲ Do not transport an applicator that weighs over 20,000

pounds (9060 kg). Loading liquid fertilizer tanks or transporting with a nurse tank hitch to the applicator can easily exceed this limit.

▲ Tow nurse tank separately. Do not tow a nurse tank in train

with the applicator on public roads.

▲ Never park an anhydrous ammonia tank on public roads or

anywhere near sites with high occupancy or high-risk populations, such as shopping areas, events, schools, hospitals, retirement communities, etc.

▲ Avoid transporting an anhydrous ammonia tank through

populated areas.

▲ Do not tow a lift-assisted 2-point applicator or nurse tank

that, when fully loaded, weighs more than 1.5 times the weight of towing vehicle.

▲ Do not transport a 2-point applicator that exceeds the

capacity or ballasting of the tractor. There may not be enough front wheel traction for safe steering.

▲ Carry reﬂectors or ﬂags to mark fertilizer applicator in

case of breakdown on the road.

▲ Keep clear of overhead power lines and other obstructions

when transporting. Refer to transport dimensions under “Speciﬁcations and Capacities” on page 154.

▲ Do not exceed 20 mph (32 km/h). Never travel at a speed

which does not allow adequate control of steering and stopping. Reduce speed if towed load is not equipped with brakes.

▲ Reduce speed on rough roads.

▲ Comply with national, regional and local laws.

▲ Do not fold or unfold the fertilizer applicator while the

tractor is moving (other than ﬁeld lift).

Introduction

Great Plains welcomes you to its growing family of new product owners. Your Nutri-Pro® 40-Foot Fertilizer Applicator (NP4000 or NP4000A) has been designed with care and built by skilled workers using quality materials. Proper setup, maintenance, and safe operating practices will help you get years of satisfactory use from the machine.

Description of Unit

The NP4000/A/B is an applicator implement for conventional liquid fertilizer, anhydrous ammonia (NH or both. It has a working width (swath) of 36 or 40 feet (11 or 12.2 m). The applicator has single or triple coulters with tines for sub-soil application from optional on-board or user-provisioned tanks.The NP4000/A/B has a lift-assisted 2-point hitch.

When conﬁgured for conventional liquid fertilizer, the NP4000 model is designed for use with an optional ground-drive CDS-John Blue® piston pump, an optional variable-rate Ace hydraulic drive pump, or a user-provisioned pump.

A11.Acme cap

Suffocation, Blinding and Burning Hazards:

See “NH3: Saﬁng Applicator Before Cart Hitch” on page 61, for safe opening procedure.

This captive cap protects the inlet when no nurse tank is connected. NH3might be sealed behind this cap.

A12.Acme inlet

The nurse tank hose coupler connects here and

A57

must have 13⁄4-4 female Acmeaswivel coupler. See page 64 for nurse tank connection.

A13.Coupler Inlet Bleed Valve

Suffocation, Blinding and Burning Hazards: See “About Bleed Valves:” on page 38.

This ﬁtting is carefully opened at normal and abnormal disconnects, to bleed NH3 liquid and vapor from the hoses (or to bleed just the nurse tank hose upon breakaway). It is also opened prior to Acme cap removal to verify that the line is discharged. See “NH3: Making Nurse Tank

Connections” on page 64, “NH3: Unhitching Nurse Tank” on page 73 and “NH3: Breakaway Event” on page 71.

A14.Breakaway Coupler

Upon Event: Probable Chemical Hazard: See “NH3: Breakaway Event” on page 71.

This assembly is designed to separate and seal the lines if between 300 to 400 pounds of pull force is applied to the nurse tank hose. In normal operations, this does not happen.

Should the hitch fail, and both safety chains fail, or an operator makes serious basic safety errors, the breakaway separates to protect the hoses from rupture. Spring-loaded checks inside the breakaway seal both ends of the now-broken connection. If the line was charged, 60 cc of liquid NH3is released on breakaway.

Resetting a parted breakaway coupler is a complex operation requiring tools. Consult the breakaway manual for details. More signiﬁcant matters are saﬁng the applicator and nurse tank, then correcting the cause of the breakaway. See “NH3: Breakaway

Event” on page 71.

A15.Breakaway Hydrostatic Relief Valve

In normal operation, this valve does not activate. It is designed to open at 375 psi, well above the 250-265 psi operating pressure of the nurse tank’s main pressure relief valve.

Operator action is periodic inspection, and to replace this hydrostatic relief valve, a time-dated part, when it reaches the end of its operating life (see page 124). See “Hydrostatic Relief Valve Maintenance” on page 122 for maintenance.

Valve function: when operating valves are closed on both sides of the breakaway (or on just the applicator side upon a breakaway event), NH3 can be trapped in the breakaway coupler. As the NH warms, it could create dangerously high pressure. This relief valve opens to vent excess pressure.

a. Acme refers to the ANSI/ASME B1.5-1997 screw thread, which has a trapezoidal thread proﬁle.

A16.Coupler Outlet Bleed Valve

Suffocation, Blinding and Burning Hazards: See “About Bleed Valves:” on page 38.

This ﬁtting is kept closed in normal operations. When the breakaway is properly coupled, the inlet bleed valve bleeds the entire assembly, and

A13

applicator supply hose. On breakaway, this valve is used to bleed the applicator side of the disconnection. See “NH3: Breakaway Event” on page 71.

A17.Supply Hose

This connects the breakaway coupler to the emergency shut-off valve. Operator action is to replace this hose, a time-dated part, when it reaches the end of its operating life (see page 124).

A18.Emergency Shut-off Valve

The handle of this is valve has a rope which is routed to the tractor cab (see page 38). Closing this valve stops NH3ﬂow to the cooler, metering system and tines. There can still be a substantial amount of NH3 in the system, for some time, with this valve closed. See the “Using Anhydrous Ammonia Safely” manual (407-551M) for emergency operation.

A19.Strainer

This ﬁlter contains a 20 mesh screen and two ceramic magnets to remove debris from the NH ﬂow.

A20.Strainer Magnets

These capture ferrous metal debris of any size. They need to be cleaned every 4 to 5 tank loads. See page 127.

A21.AccuFlow™ Super Cooler (Heat Exchanger)

For effective application, NH3needs to remain in the liquid state until released underground. This is accomplished by refrigeration. Some of the ﬂow is tapped , fed back to the cooler at , vaporized and used to chill the ﬂuid passing from to .

A32 A34

A22 A24

A22.Cooler Intake

Liquid NH

enters the cooler here.

A23.Cooler Hydrostatic Relief Valve

In normal operation, this valve never activates. NH

can get trapped in the system between the emergency shut-off valve and the On/Off

A31

valve , if both valves are closed while the system

A18

is charged. As the liquid warms and pressure rises, this valve protects the system with periodic releases.

This valve is set to activate at 350 psi, higher than the nurse tank’s relief valve.

Operator action is periodic inspection, and to replace this hydrostatic relief valve, a time-dated part, when it reaches the end of its operating life (see page 125). See “Hydrostatic Relief Valve

Maintenance” on page 122 for maintenance.

A24.Cooler Outlet

Chilled liquid NH3 exits the cooler here.

A25.Flow Meter

This ﬁtting converts ﬂuid ﬂow to pulses for the SCS 450 controller. It has a range of 1-60 gpm. A tag on the cable lead provides a “METER CAL” number speciﬁc to the installed meter (and accurate only for NH3 ﬂuid ﬂow, and not NH3 vapor ﬂow).

A26.Drain Cap

The plumbing cross and lower cap below the temperature gauge are provided to allow the gauge

probe to be exposed to the full NH3 stream. This cap does not require periodic clean-out.

A27.Temperature Gauge

This gauge reports the temperature of the chilled, ﬂowing, NH3. When NH3 is not ﬂowing, this gauge slowly drifts up to ambient temperature.

Checking the temperature and pressure gauges

A28

against the chart in the “Using Anhydrous Ammonia Safely” manual (407-551M), or in the Raven AccuFlow™ manual, indicates whether the ﬂowing NH3 is in a liquid state.

Normal ﬁeld temperatures of the chilled ﬂowing NH

are in the range 20 to 83°F (-7 to 28°C).

Page 28

24 2013+ NP4000/A/B Table of Contents Index Great Plains Manufacturing, Inc.

A28.Pressure Gauge

This gauge reports the pressure of the NH exits the cooler. If line valves are closed, a pressure reading above zero indicates NH between the emergency shut-off valve and the On/Off solenoid valve (the Control Valve

A31 A30

is present

A18

does not completely close).

Checking the pressure and temperature against the chart in the “Using Anhydrous Ammonia Safely” manual (407-551M), or in the Raven AccuFlow™ manual, indicates whether the ﬂowing NH3 is in a liquid state.

When valves are open but NH3 is not ﬂowing, this gauge normally reads within 5 psi of the nurse tank pressure gauge . If they are materially different

A67

at zero ﬂow, one of the gauges may be defective.

When NH3 is ﬂowing, the pressure reported by this gauge is lower than the tank pressure.

A28

A29.Cooler Bleed Valve

Suffocation, Blinding and Burning Hazards: See “About Bleed Valves:” on page 38.

This valve is normally closed. It is used to bleed trapped NH3 from the cooler system when valves are closed. It can also be used to accelerate clearing the cooler system for maintenance.

A30.Control Valve

This is a variable electronic valve controlled by the SCS 450. It is the primary control point for application rate. When power is off, this valve remains at its most recent setting.

This valve has a visible indicator above the valve ball casing, indicating whether open, closed or in between.

When commanded to a rate of zero, this valve does not completely close. Use shut-off valves to completely stop ﬂow. A full slew from fully open to minimum takes approximately 9 seconds.

A27

after it

A31.Master Shut-Off Valve

This is the normal control for starting and stopping total application ﬂow in the ﬁeld (for turns, etc.). This component is an open/close solenoid valve controlled by the “MASTER” switch on the SCS 450. When power is off, this valve remains at its most recent setting.

This valve has a visible indicator above the valve ball casing, indicating whether open or closed.

Operation of this valve is essentially instantaneous. Its valve ball is equipped with a downstream relief oriﬁce.

A32.Refrigerant Tap

A small amount of the NH3ﬂow is taken at this point to provide refrigeration at the cooler. There are no operational items for this ﬁtting.

A33.Refrigerant Line

This tubing passes tapped refrigerant NH3 to the cooler. Operator action is to replace this tubing, a time-dated part, when it reaches the end of its operating life. See page 125.

A34.Cooler Refrigerant Inlet

Tapped refrigeration ﬂow enters the cooler at this ﬁtting, and is vaporized to chill the liquid entering at

A22

ﬁtting . There are no operational items for this ﬁtting.

A35.Section Control Check Valve

(Section Control Option Only) This prevents back ﬂow when section shut-off valves are off with NH3 present. There are no

A39

operational items for this ﬁtting.

A36.Section Control Bleed Valve

Suffocation, Blinding and Burning Hazards: See “About Bleed Valves:” on page 38.

(Section Control Option Only) This valve is normally closed. It is used to bleed trapped NH3 from the section control system if all section valves are closed.

A37.Section Control Relief Valve

(Section Control Option Only) In normal operation, this valve never activates. NH3can get trapped in the system between the section control check valve and the section shut-off valves , if all section valves are closed

A39

A35

while the system is charged. As the liquid warms and pressure rises, this relief valve protects the system with periodic releases.

This valve is set to activate at 350 psi.

Operator action is periodic inspection, and to replace this hydrostatic relief valve, a time-dated part, when it reaches the end of its operating life (see page 125). See “Hydrostatic Relief Valve

Maintenance” on page 122 for maintenance.

A38.Section Flow Divider

(Section Control Option Only) This is a CDS-John Blue®Impellicone® manifold. It evenly splits the NH3 ﬂow for distribution through the row ﬂow dividers . There are no operational

A40

items for this component.

A39.Section Shut-Off Valves

(Section Control Option Only) These are the normal controls for suspending per-section application ﬂow in the ﬁeld (for point rows, pass overlap, etc.). These are open/close solenoid valves controlled by the “BOOMS” switches on the SCS 450.

When used with the SCS 450 or other suitable sectional application controller, shutting off a section causes the total ﬂow to be reduced by1⁄3of the all-sections-on rate, keeping the rate constant for the section(s) still active.

Each section valve has a visible indicator above the valve ball casing, indicating whether open or closed.

Operation of each section valve is essentially instantaneous. However, there is considerable residual NH3in the section ﬂow divider and delivery tubes after shut-off. When console power is off, the valves remain at their most recent setting.

The valve balls are equipped with a downstream relief oriﬁce.

A40.Row Flow Divider(s)

This is a CDS-John Blue®Impellicone® manifold. It evenly splits the NH3 ﬂow for distribution through the delivery tubes . There are no operational

A45

items for this component.

A41.Flow Divider Manifold Inlet

NH3 liquid ﬂow enters the ﬂow divider here.

A42.Flow Divider Pressure Gauge

This gauge reports the pressure prior to ﬂow division. It normally reads lower than the cooler and nurse tank pressure gauges.

A43.Flow Divider Outlet

Each of these ports receives an equal fraction of the NH3 liquid ﬂow.

A44.Flow Divider Plug

Unused ports are plugged with a steel NPT plug. Unused ports do not affect ﬂow balance at the other ports.

A45.Delivery Tube

This tubing passes NH3 liquid ﬂow to the tines. Operator action is to replace this tubing, a time-dated part, when it reaches the end of its operating life. See page 126.

A46.Coulter Tine (Single)

Tines inject the liquid NH3. All but two (or four) of the rows are equipped with tines having a single smaller liquid delivery tube. Tines need frequent inspection for wear and damage.

A47.Cooler Vapor Outlets (2)

Two vapor outlets direct the now-gaseous refrigerant ﬂow (that entered at ) to two special

A49

tines per cooler.

A34

A48.Vapor Tube

This tubing passes NH3vapor ﬂow to the dual tines. Operator action is to replace this tubing, a time-dated part, when it reaches the end of its operating life. See page 126.

A49.Coulter Tine (Dual)

There are two of these special tines per cooler (four total on a dual-cooler applicator). They direct the vaporized refrigerant NH3 gas into the soil at the larger rear vapor tube. They are otherwise identical to the single-tube tines .

( - ). The present manual lists only those required for applicator ﬁeld operations.

A56.Acme Parking Plug

A threaded stud (or other means) for storage of the outlet hose when not coupled to the applicator.

Excess NH3 Release Hazard:

If the outlet hose is entirely dismounted (both ends free) for transport and storage, and both ends are 13⁄4-4 Acme, be sure about which end is which. Installing a hose backwards can result in needless excess NH

release at

unhitching, or a line segment unprotected by bleed and/or relief valves.

A57.Acme Female Hose Coupler

This end of the hose connects the tank withdrawal

A63 A12

valve to the leading applicator inlet at the breakaway coupler. For use with a Nutri-Pro

applicator, the outlet end of the hose must be equipped with a 13⁄4-4 female Acme ﬁtting.

The outlet end of the hose has a swivel collara or shroud containing the female Acme ﬁtting. This allows connection without needing to twist the hose.

Acme hose couplers are intended for hand tightening only. Do not use tools to make the cart-applicator connection. A liquid-tight seal is made by the gasket in the male Acme ﬁtting on the applicator break-away coupler.

For dual-tank carts, each tank usually has its own hose.

A58.Outlet Hose Assembly

The hose may have zero, one or two operating valves , one or more bleed valves , and a hydrostatic relief valve . The outlet end may

A60 A61

A62

have an Acme. plug.

Hose valves are typically hand wheel valves, or lever valves. Read any documents provided for the valves. Have the terminal or dealer explain how the valves work.

Suffocation, Blinding and Burning Hazards:

Never test an anhydrous ammonia hose valve unless you are absolutely certain the hose and valve bodies are empty, or both hose ends are securely connected to sealed systems.

▲ A two-valve hose can contain a substantial amount of

even when completely disconnected. See “Avoid

Line Traps” on page 116.

▲ Older ball valves can contain NH3 inside the ball

when closed, even though disconnected at both ends. See “Avoid Ball Traps” on page 117.

Follow instructions for bleeding and checking. Never use a valve handle as a carrying handle. Keep hands clear of bleed valves when carrying a hose.

A59.Nurse Tank Hose Body

NH3 hoses are time-dated components. Operator action is to replace the assembly when it

A58

reaches the end of its operating life.

A60.Hose Valve(s)

The hose may have zero, one or two operating valves .

A60

Excess NH3 Release and Trapping Hazards:

Understand hose and tank withdrawal valve functions and sequencing. This manual presumes a hose with a single outlet-end shut-off valve , and a tank outlet with a withdrawal valve . If the hose in use is

A60

A65

different, have the hose provider explain the correct order for operations.

a. Acme collars may be aluminum, but all internal coupler components must be NH3-safe, typically stainless steel.

A61.Bleed Valve(s)

Suffocation, Blinding and Burning Hazards: See “About Bleed Valves:” on page 38.

Hose valves typically have bleed valves. Have the hose provider explain exactly what is bled by each bleed valve.

The purpose of a bleed valve is to perform a controlled release, via an oriﬁce, of any ﬂuid or gas trapped in the closed line prior to disconnect at a nearby Acme ﬁtting.

A single bleed valve may be located on the inlet or outlet side of the valve, and only protects that side of the circuit when the valve is closed. More rarely, a shut-off valve has bleed valves on both sides of the valve. An older ball valve may have a bleed valve for the ball itself.

A65.Withdrawal Valve

In ﬁeld operations, this valve is

opened ﬁrst, and closed ﬁrst.

Ammonia Release Hazard:

Never open the withdrawal valve unless: a. all other valves and bleed valves, are closed, or; b. the applicator is conﬁgured and ready for use. Always be on the up-wind side for valve operation. Always open slowly. Always check for signs of release when opening this valve.

The withdrawal valve is the application outlet valve. It is usually located on the tank top, but may be located on the bottom. It is color coded red or orange.

A67.Pressure Gauge

This gauge reports the pressure (usually in psi) of the NH3 gas at the top of the tank. The reading varies with tank and ammonia temperature.

Liquid System Narrative

Tank, plumbing and setup requirements differ for ground drive and hydraulic drive applicators. The next few pages provide an overview of both systems.

Refer to Figure 6 on page 29 and Figure 5 on page 28

Note: Callouts L11 to L51, correspond to the items

beginning below, and identify the same components throughout this manual.

This list presumes that the applicator has system components factory-installed by Great Plains. The list includes all components for either the preset or hydraulic drive pumping system.

If the applicator has aftermarket components, part or all of this information may not apply to your operations. Consult the manual or other documentation for your tank or pump.

L11. Application Tank

Tank Option: The system depicted shows the optional twin 300 gallon tanks, which includes the quick-ﬁll inlet assembly. A user-provisioned fertilizer supply tank may be a trailing nurse tank cart, or may be tractor-mounted.

A trailing nurse tank cart requires the optional nurse tank hitch (page 145) on the applicator. The cart must be full-trailering, and not semi-mounted. The Great Plains plumbing systems are not pre-conﬁgured for user-provisioned tanks.

System Clogging Risk:

Use only pre-mixed liquid fertilizer. Regardless of the tank type used, or its capabilities, do not use dry fertilizer mixes with the Nutri-Pro® applicator.

L12. Vented Tank Lid

Tank Option: A fully sealed tank must be vented during operation. If the tank has a control for this, it may be part of the top tank lid, or a separate valve.Each on-board tank has a 10 inch vented screw-on lid. Tanks may be ﬁlled at the top or via the quick ﬁll .

L16

L13. Tank Discharge Valves

Tank Option: Each on-board tank has its own valve, which switches the tank discharge port between these states:

tank connected to selector valve

L15

tank discharge closed (shut off at valve) tank connected to tank drain elbow

L14

Discharge valves are normally open to the selector. The may be closed individually to prevent tank-to-tank transfer on slopes.

L14. Tank Drain Elbow

Tank Option: This open elbow ﬁtting is used for material recovery and tank wash-out (page 128).

L15. Selector Valve

Tank Option: This valve is included with the optional on-board tank system. The valve switches the tank plumbing between three states:

tank plumbing connected to inlet

L16

tank plumbing shut off at valve tank connected to pump system ( , )

L19 L27

L16. Supply Inlet

Tank Option: With the optional on-board tanks, or without the tanks, but with the trailer hitch option, the inlet of the NP4000 applicator is a 2 inch cam-lock quick coupler receptacle (female, FCL). The tank supply hose ﬁtting must be, or be adapted to 2 inch MCL.

L17. Inlet Shut-Off Valve

Tank Option: This valve is open only during tank ﬁlling with on-board tanks. This valve is customer-provisioned for tractor-mounted or trailing nurse tank conﬁgurations.

L18. Strainer

Tank Option: This ﬁtting contains an 80 mesh screen for ﬁltering large particles and coagulates in the fertilizer, preventing blockage at the oriﬁce plates . See page 100 for alternative screen

L38

sizes and page 129 for maintenance.

L19. Ground Drive Pump

Ground Drive Option: The CDS-John Blue NGP-7055-K has a capacity of 34 gallons/minute (129 liters/minute). See the 12-M-43 CDS-John Blue NGP Pump Parts and Instructional manual for maintenance.

L20. Pump Adjustment Dial

Ground Drive Option: This 0-to-10 adjustment sets the percentage of rated gpm/lpm to use. Settings below 2 are not recommended.

Pump and application rate are set by a combination of ground drive sprockets (not shown) and dial setting. See page 95 for ground drive rate setting.

L21. Pump Adjustment Tool

Ground Drive Option: Adjusting the setting dial may require some mechanical assistance. A slot is provided to store the tool at the pump when not being used for adjustments.

417-199M Table of Contents Index 2014-05-14

Page 35

Great Plains Manufacturing, Inc. Table of Contents Index Application Overview 31

L22. Passive Manifold

Ground Drive Option:

The factory conﬁguration of this ﬁtting has two outlets capped. The third is plumbed to the optional front boom.

With user-provisioned ﬁttings and hoses, this manifold can split the ﬂow across two booms, or across three sections of a single boom.

However conﬁgured, equal ﬂow is assured by the oriﬁce plates .

L38

L23. Gauge Protector

Ground Drive Option: This ﬁtting transmits manifold pressure to the pressure gauge , and protects

L24

the gauge from direct contact with corrosive fertilizer.

L24. Pressure Gauge

Ground Drive Option: This 0-to-100 psi gauge reports the pressure in the manifold, which is typically 15-to-40 psi during application. The pressure should be above zero only when fertilizer is ﬂowing. The back-pressure at the nozzle oriﬁces falls quickly when the pump stops.

L38

Check the pressure periodically during application. If it rises to over 65 psi, the relief valve may be activating. See also pressure sensor .

L25

L32

L25. Relief Valve

Ground Drive Option: Adjust this valve to activate at 65 psi (page 103). This valve protects the manifold against blockages, and from over-pressure due to oriﬁce sizes too small for the application rate or the material viscosity.

L26. Dump Line

Ground Drive Option: If the relief valve

L25

operates, material is jettisoned at this tube. If you observe dumping, check the pressure and review the oriﬁce plate conﬁguration.

L38

L27. Hydraulic Drive Pump

Hydraulic Drive Option: The Ace FMC-150F-HYD-206 has a capacity of up to 150 gallons/minute (560 liters/minute). See the HYD-MAN Ace Pump Instruction manual for maintenance.

L28. Air Bleed Line

This line to the tank enabled pump priming by bleeding off air. If using an off-applicator tank, a user-provisioned bleed line or bleed valve must be provided for pump priming.

L29. Flow Control Valve

Hydraulic Drive Option: Under the control of the console (not shown) this valve is being constantly adjusted to regulate pump output to the current application rate (as reported by the ﬂow meter ). Only one ﬂow control valve can be controlled by a single Raven SCS 450 console.

L30. Flow Meter

Hydraulic Drive Option: This sensor reports the actual material rate entering the hydraulic drive manifold. As it detects variations from your desired rate, it signals the console to adjust the control

L29

valve . Only one ﬂow meter can be monitored by a single Raven SCS 450 console.

L31. Section Valves

Hydraulic Drive Option: There are three On/Off solenoid valves (1, 2 & 3).

The factory conﬁguration uses only valve 1. Valves 2 and 3 have their outlets capped.

The valves open and close under the control of BOOMS switches on the Raven SCS 450a or other compatible console.

L32. Pressure Sensor

Hydraulic Drive Option: The optional Raven SCS 450 console displays the manifold pressure during operation. This is measuring essentially the same pressure as the mechanical pressure gauge . Only one pressure sensor can be

L24

monitored by a single Raven SCS 450 console.

L33. Boom

Boom Option: There is one boom assembly per applicator section. Booms may be different lengths, and have different drop counts at center and on wings.

The factory conﬁguration provides the booms interconnected as a single section.

L34. End Cap

Boom Option: In the factory conﬁguration, the wing booms each have a cap. These caps are removed for clean-out (see page 128).

L30

a. Although the Raven SCS 450 has six section valves, the harness provided has only four Valve leads. Controlling more than three

valves with a single SCS 450 would require the purchase of an alternate harness from Raven.

Page 36

32 2013+ NP4000/A/B Table of Contents Index Great Plains Manufacturing, Inc.

L35. Boom Clamp

Boom Option: This ﬁtting taps the boom for delivery to the row. it contains an 8 psi check valve, which prevents dribbling when the system is idle. Seasonal clean-out (page 128) is necessary to prevent over-winter freezing of residual material.

Booms typically have more boom clamps than applicator rows (the same boom assembly is used on multiple applicator models). Active rows have nozzle bodies . Inactive stations have shutoff

L36

caps .

L39

L36. Shutoff Cap

Boom Option: Unused boom clamp stations are capped. Use a gasket (with or without plate) under a cap.

L37. Gasket

Boom Option: This ﬂat O-ring seals the nozzle

L39 L36 L35

body or shutoff cap to the boom clamp . The inside diameter of the gasket is grooved to accept an oriﬁce plate . Do not operate without a

L38

gasket.

L38. Oriﬁce Plate

Boom Option: These stainless steel plates restrict the ﬂow to the row. Their function is to create back-pressure to the pump, and ensure equal ﬂow at all rows.

The standard boom option includes complete sets of plates at three sizes. Additional plate sizes are available. The oriﬁce size must be matched to the rate and viscosity of the material being applied. See page 101 for plate selection and installation.

L39. Nozzle Body

Boom Option: This ﬁtting adapts the boom clamp to tubing, and may be positioned for forward or rear tubing direction.

L40. VeriFlow Nozzle (Option)

This accessory replaces components , and

L39

with a spring-regulated valve nozzle that

L37 L38

requires no adjustment (or oriﬁce plate changes) over a wide range of ﬂow rates.

L41. Drop Tubing

Boom Option: This tubing carries the material to the row.

L42. Coulter Arm and Tubing

Coulter Option: The tubing is protected behind arm structure. The arm may be adjusted for release depth relative to coulter depth (page 90).

L43. Tine Nozzle

Coulter Option: This stainless steel ﬁtting (part number 828-046C) delivers the material to the trench opened by the coulters. It has an 0.040 in. oriﬁce port.

Preparation and Setup

This section helps you prepare your tractor and fertilizer applicator for use, and covers tasks that need to be done seasonally, or when the tractor/fertilizer applicator conﬁguration changes.

Before using the applicator in the ﬁeld, you must hitch it to a suitable tractor, inspect systems, level the applicator, and then hitch a suitable nurse tank to the applicator. Before using the fertilizer applicator for the ﬁrst time, and periodically thereafter, certain adjustments and calibrations may be required.

Anhydrous Ammonia Exposure Hazard:

NP4000A models: Do not modify the NH3 system of this applicator. Designing NH3 systems, selecting and installing components is serious engineering. Testing a custom system could be extremely hazardous (and ﬁeld PPEa is inadequate for such testing). Malfunction of a custom system could result in a major release of NH3 gas or liquid.

Initial Setup

See manual 417-199Q for pre-delivery items (normally completed by dealer).

Other ﬁrst-time/infrequent setup tasks include:

• Set lift assist valve (page 177).

• Install meter console in tractor (page 179).

• Install any Options not factory- or dealer-installed.

Post-Delivery/Seasonal Setup

On initial delivery, use with a new tractor, and seasonally, check and as necessary, complete these items before continuing to the routine setup items:

• Bleed hydraulic system (page 132).

• De-grease exposed cylinder rods if so protected at last storage.

• Verify that all time-dated components are within their service lives.

Anhydrous Ammonia Release Hazard:

Use only the Great Plains rear hitch for a trailing nurse tank cart. A custom hitch and/or mount, including any safety chain anchors, could fail entirely, resulting in a tank cart upset. Consequences could include a catastrophic release of NH3. At the very least expect a breakaway event and cart damage.

Anhydrous ammonia is 82% Nitrogen, the highest of any fertilizer. The compound NH ambient temperatures. It is retained in the soil only by chemical reactions and physical mechanisms, primarily reactions with soil moisture.

Consult with your agronomist about optimal application timing, rate and depth, based on proposed crop, soil temperature, soil moisture content and ambient temperature. Non-optimal applications can result in NH loss to the atmosphere, soil drying, and undesired long term changes in soil pH.

Pre-Application Setup

Complete this checklist before routine setup:

❑ Read and understand “Important Safety

Information”, pages 1 to 17.

❑ Check that all working parts are moving freely, bolts

are tight, and cotter pins are spread.

❑ Check that all grease ﬁttings are in place and

lubricated. See “Lubrication and Scheduled Maintenance” on page 139.

❑ Check that all safety decals and reﬂectors are

correctly located and legible. Replace if damaged. See “Safety Decals” on page 9.

❑ Inﬂate tires to pressure recommended and tighten

wheel bolts as speciﬁed. See “Tire Inﬂation Chart” on page 159.

Hitching Tractor to Applicator

This manual presumes the following (recommended) operations sequence:

1. Hitch tractor to applicator for transport (next page)

2. Transport applicator separately from nurse tank: page 59

3. Hitch nurse tank to applicator at ﬁeld: page 76

To prevent soil compaction on rows, set tractor wheels between rows, for example: 60 inches center-to-center. For hillsides and steep slopes, set tractor wheels as wide as possible for maximum stability.

Anhydrous Ammonia Exposure Hazard:

NP4000A models: Use a tractor with a fully enclosed cab. A tractor that is not fully enclosed exposes the operator to substantially more NH3 vapor, particularly if ﬁeld requirements result in downwind turns or downwind passes.

Repeated exposure to NH3 vapor may exceed PEL (Permissible Exposure Limits) and also induces olfactory fatigue (adaptation). Over time, you become less sensitive to ammonia odor, and may fail to recognize dangerously high concentrations.

Loss of Control / Public Safety Hazards:

Do not transport on public roads with a conventional or anhydrous nurse tank hitched to the applicator. Transport with an anhydrous ammonia nurse tank hitched to an applicator is illegal in many places. See “Transport” on page 59.

2-Point Hitching

Crushing Hazard:

Do not stand or place any body part between applicator and moving tractor. You may be severely injured or killed by being crushed between the tractor and applicator. Stop tractor engine and set parking brake before attaching cables and hoses.

The NP4000/A/B is engineered to be used with Category II or Category III tractors.

Refer to Figure 8

This applicator is factory set for Category III tractors. Category II requires an optional hitch pin kit (see page 144).

In addition, the following bushings (not supplied by Great Plains) may be needed to ﬁt your quick hitch or tractor’s 3-point arms:

• Lower Links:

⁄8in. (28.6 mm) I.D. × 17⁄16in. (36.5 mm) O.D.

1. Adjust tractor lower links to maximize lifting height.

2. Normally the lower arms engage pins in the lower

holes of the applicator’s three point lugs. You may use the upper holes if necessary.

3. Set tractor sway blocks to minimize side sway. Set tractor hitch lift control to Float.

4. Back tractor up to applicator. Align lower links with the lower hitch clevis on applicator. Adjust hitch bushings and spacers supplied with applicator according to the category of your tractor. Lock pins in place.

5. Set hitch for Depth Control mode.

NP4000A: Emergency Shut-Off Rope

This part of hitching requires operating the emergency shut-off valve. If the applicator was correctly shut down and discharged after last use, there is no anhydrous ammonia liquid in the system, and only small amounts of vapor, at low pressure. If the applicator was improperly shut down, checking the emergency valve could be hazardous.

A18

Possible Chemical Hazard:

Wear your NH points. Residual NH

PPEa. Be up-wind of any possible release

(possibly in dangerous quantities) may

be present in the applicator systems, from the inlet Acme

About Bleed Valves:

The purpose of a bleed valve is to perform a controlled release, via an oriﬁce , of any ﬂuid or gas trapped in

the closed line prior to operating other valves or uncapping at a nearby Acme ﬁtting.

If the line is discharged, opening the valve may have no result, or may release a small amount of NH3 vapor at low pressure. If there is a low pressure release, leave the valve open at the current position. Move away up-wind. Return when the release concludes.

If the line was not discharged, opening a bleed valve may release NH3vapor at high pressure, or may release NH liquid, most likely as a spray.

If the there is liquid in the line segment, completion of a bleed can take a long time. As the ﬂuid turns to vapor, it chills the remaining ﬂuid, slowing evaporation.

If opening a bleed valve results in an unexpected large discharge, immediately close the valve and follow the instructions for discharging the system (page 118).

Suffocation, Blinding and Burning Hazards:

Be up-wind when operating a bleed valve. Wear chemical gloves when operating a bleed valve. Wear goggles when operating a bleed valve. Do not place your body or head in front of the oriﬁce. Follow a check-list when operating a bleed valve. Open a bleed valve slowly. Leave it open until all ﬂuid and vapor ﬂow ceases. This can take a long time.

it.

7. Locate the emergency rope .

8. Inspect the attachment of the rope to the valve handle, and the rope itself. Replace the rope if cut, frayed or worn. If the handle connection is not secure, take corrective action.

9. Uncoil the rope. Remove any knots.

10. Route the rope forward and above the plumbing center-line (but otherwise near center-line), toward the tractor cab. Avoid having the rope rest on or rub against any applicator or tractor parts that could cause a snag or abrasion. Avoid running too far sideways, or operation may bend the handle.

11. Route the rope into the tractor cab.

Rope Function Hazard:

Avoid rope routes at or below plumbing centerline. Routes below plumbing center-line cannot operate the valve. Routes at plumbing center-line may fail to operate the valve.

Avoid rope routes that are too vertical. A rope running at a high angle may fail to fully close the valve.

Note: On a 2-point applicator, the tractor cab may be

high enough to provide the angle needed. On a pull-type applicator, it may be necessary to route the rope(s) over the transport rest.

12. Test each rope. Make sure each rope can quickly and smoothly close its valve.

Hydraulic Hose Hookup

High Pressure Fluid Hazard:

Shut down tractor before making hydraulic connections. Only trained personnel should work with system hydraulics.

Escaping ﬂuid under pressure can have sufﬁcient pressure to penetrate the skin causing serious injury. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

Use paper or cardboard, NOT BODY PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems.

Refer to Figure 14

folda cylinder base end (lift cylinder rod end), or the return side of a hydraulic motor.

• The hose under a retracted-cylinder symbol feeds a

fold cylinder rod end (lift cylinder base end), or the pressure side of a hydraulic motor.

Use a regular remote and not a dedicated tractor 3-point remoteb.

Secure hoses and cables so that they have sufﬁcient slack for hitch movements, but cannot get caught between moving parts of fertilizer applicator. Failure to safely route and secure hoses and cables could result in damage requiring component repair/replacement, and lost ﬁeld time.

Machine Function Risk:

The NP4000/A/B weight transfer system requires a tractor with closed center hydraulics. Open center hydraulics are incompatible.

a. Fold and lift functions are combined on the NP4000 product family. When fold is extending, lift is retracting. The handles are coded for

fold priority. For the Extend/Retract terms in this manual to have their intended results, connect the extend and retract handled hoses to extend and retract remote ports respectively.

b. Some tractors provide a special remote pair at the 3-point hitch arms. On some tractor models, this circuit has speciﬁc ﬂow and/or

pressure-sensing behavior intended for certain applicators (other than Nutri-Pro®). Nutri-Pro® lift and/or fold and weight transfer may not function on this type of circuit.

Hydraulic Pump Hookup (Option)

The hydraulic pump used has a 7 gpm (23 liters/min.) motor. If the tractor used does not have the capabilities to adjust the remotes down to this ﬂow, then a Hydraulic Flow Divider Kit must be installed so that ﬂow can be controlled to prevent operating the pump at excessive speeds. See a Great Plains dealer for more information.

Outlet Port

Inlet Port

If the tractor has only one circuit capable of continuous ﬂow or only one capable of adjustable continuous ﬂow, reserve that circuit for the pump, and use another for the main applicator functions.

1. Connect the pump hydraulic hoses to suitable tractor remotes.

Date Code

Refer to Figure 15

2. The pressure hose coming out of the tractor remotes

Motor Model (206N)

must be connected to the motor inlet port:

“I”, Base end on hose label),

and the return line connected to the motor outlet:

Figure 15

Ace Pump Connections

“O”, Rod end on hose label.

3. Before operating, place a stop in the neutral position for the tractor hydraulics so that the hydraulic lever can only be moved to the ﬂoat and down positions. Refer to the tractor operator manual or tractor dealer on information for the neutral stop.

4. See page 78 for setting ﬂow rate.

Equipment Damage Risk: DO NOT move the hydraulic lever into the Neutral position while the hydraulic pump is running. To do so may cause damage to the hydraulic pump.

Raise Parking Stands

Refer to Figure 16

Heavy Object Hazard:

Use the lifting handle . Push leg against frame while raising or lowering. The leg weighs approximately 45 pounds (20 kg). The leg could cause injury if you lose control of it while raising or lowering.

1. Use tractor 2-point hitch and the fold/lift circuit to slightly raise the applicator. See “Raising/Lowering Applicator” on page 51.

2. Remove cotters from pins .

3. Grasp the lifting handle. Use an assistant or shoulder to hold leg against frame and inside ﬂanges.

4. Remove the pins .

5. Lift or lower the stand straight up or down.

6. Re-insert pins. Secure with cotters.

Leveling Applicator

During initial setup and periodically throughout the season, check that the applicator runs level. When applying fertilizer, the top of the main frame should be parallel to the ground, and level left to right.

Set Application Depth

Before checking or correcting side-to-side or front-to-back level, set the application depth (which is controlled by tool bar height).

The Nutri-Pro application at:

0 to 6 inches (0 to 15.3 cm) For adjustment, see “Vantage I Coulter Adjustments” on page 89.

To check level, lower the applicator into the ground in representative conditions.

Front-to-Back Level (Spacers)

The rear lift-assist assembly must be set to match the gauge wheels and 2-point hitch in front. Lift-assist lowered height is controlled by (provided) spacers on the lift cylinder rods.

To set:

1. Lower applicator until lift assist wheels are just off

the ground.

2. Raise applicator until wheels touch ground just ﬁrmly

enough to resist spinning.

Refer to Figure 18

3. Insert a combination of spacers to ﬁll the space on

the rod between the cylinder end and clevis.

4. Raise and lower applicator. Pull forward and check

coulter depth and front-to-back level. Adjust spacers as required to achieve desired application depth.

5. Store unused spacers on any nearby hydraulic hose.

Make sure the spacers cannot slide into positions that interfere with machine functions.

Meter / Variable Rate Setup (Option)

This topic presumes that the Nutri-Pro® applicator has one or more Raven SCS 450 consoles, speed radar, ﬂow meter, pressure sensor, section control valves, and, for anhydrous models, single or dual Raven AccuFlow™ metering system. It also presumes that the console has been installed in the tractor cab per “Console Installation” on page 179.

L32

If the Nutri-Pro® applicator has dealer- or user-provisioned controller or metering, carefully follow supplier documentation for installation, setup, use and maintenance. This Nutri-Pro® manual (417-199M) cannot describe your system. Great Plains cannot assume any liability for results with equipment not supplied by Great Plains.

Before ﬁrst ﬁeld use of the SCS 450, it must be programmed with data specifying the system conﬁguration, consisting of various “CAL” numbers and user elected “RATE” numbers. See the Raven SCS 450 manual for display interpretation, and see the manual or the Calibration Card for the keystroke sequence for setting each of these values.

This data is retained as long as the SCS 450 remains connected to battery power. If power is removed for electrical work, long term tractor parking or welding, the data is lost and must be re-entered.

SCS 450: BOOM CAL

Anhydrous models without section control have one “boom section” (BOOM 1, whether single- or dual-cooler). The BOOM CAL number is simply the applicator swath on single-section applicators. See the table on page 46.

Hydraulic pump models and anhydrous models with section control have three boom sections. See the table on page 46.

SCS 450: SPEED CAL

A speed sensor connection to the Raven SCS 450 is required. Perform a calibration per the manuals for the sensor and the SCS 450.

A speed sensor input allows the SCS 450 to determine and control application rates at arbitrary ﬁeld speeds.

Note: The Great Plains Raven AccuFlow™ and SCS 450

bundles do not include a speed sensor, nor the cable necessary to connect a Raven-compatible sensor or radar to the SCS 450 See page 149 for an available radar kit. See page 169 for harness cables available from Great Plains or Raven.

Note: Two-product applicators using two SCS 450

consoles usually require an additional Y-cable.

This is your primary desired application rate, typically in gallons per acre.

SCS 450: RATE 2 CAL

This is your secondary desired application rate, typically in gallons per acre. If you have no alternate rate preferred, set this to RATE 1 CAL, so that the control valve won’t slew if you need to switch to MAN mode.

SCS 450: TANK VOL

Optional. If entered, the material consumed (as measured by the ﬂow meter) is continuously subtracted from this number, and may be used to signal a low tank alarm. The number needs to be re-entered at each reﬁll.

SCS 450: TIME

Optional. The SCS 450 (which is always in 24:00 hour time format) defaults to 00:00 (and resets to that after 10 days of inactivity). You may use this menu to set the actual time.

Wash Water (NP4000A)

Refer to Figure 20

Empty the 10 gallon applicator First Aid Water tank. Reﬁll it with fresh clean water. If the nurse tank cart is at hand, reﬁll the nurse tank wash water as well.

The water needs to be changed daily. Water absorbs ammonia vapor from the air, and becomes an ammonium hydroxide solution over time.

When emptying wash tanks, use the time and water to train operators on tank operations, and ﬁrst aid rinsing procedures.

Sealer Setup (NP4000A)

From the factory, sealers are preset for optimal shipping conﬁguration. The factory default settings are not likely to be suitable for your ﬁeld conditions.

Adjustments may also be required for different ﬁelds and from season to season.

Operating Instructions

This section covers general operating procedures. Experience, machine familiarity and the following information will lead to efﬁcient operation and good working habits. Always operate farm machinery with safety in mind.

Pre-Start Checklist

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can have sufﬁcient pressure to penetrate the skin. Check all hydraulic lines and ﬁttings before applying pressure. Fluid escaping from a very small hole can be almost invisible. Use paper or cardboard, not body parts, and wear heavy gloves to check for suspected leaks. If injured, seek immediate medical attention from a physician familiar with this type of injury.

This checklist presumes that the nurse tank is not yet connected.

❑ Carefully read “Important Safety Information” on

page 1.

❑ Empty the applicator’s 10 gallon wash water tank,

Reﬁll it with fresh clean water.

❑ Review the Material Safety Data Sheet (MSDS) for

the anhydrous ammonia.

❑ Check that all time-dated applicator components are

still within their speciﬁed service lives.

❑ Check all plumbing components, hose, tubing and

ﬁttings are in satisfactory working condition.

❑ Lubricate fertilizer applicator as indicated under

“Lubrication and Scheduled Maintenance” on page 139.

❑ Check all tires for proper inﬂation. See “Tire

Inﬂation Chart” on page 159.

❑ Check all bolts, pins, and fasteners. Torque as

shown in See “Torque Values Chart” on page 159.

❑ Check fertilizer applicator for worn or damaged

parts. Repair or replace parts before going to the ﬁeld.

❑ Check hydraulic hoses, ﬁttings, and cylinders for

leaks. Repair or replace before going to the ﬁeld.

Fold/Lift Circuit

The fold and lift cylinders share a single hydraulic circuit. Solenoid valves (controlled by a switch box), one or more passive valves, and mechanical locks control hydraulic sequencing.

This system design provides a partial fold, as a single self-limiting hydraulic operation, during ﬁeld lift, providing extra wing clearance in ﬁeld turns.

If the hydraulic harness is not connected at the hitch, or the switch box is off, or power is off, most valves default to an Open state.

FOLD / FIELD Switch

Refer to Figure 21 (depicting the switch in PARK)

This switch is mounted in the tractor cab (page 176), and connected to the applicator at the hitch. It controls several solenoid valves on the applicator. It has three toggle positions and two indicator lamps.

Note: The switch is powered by the tractor. An illuminated

lamp indicates power sent to the harness. The harness must be connected at the hitch for the function to be effected.

Machine Damage Risks:

Lift/lower (except ﬁeld lift) and fold/unfold operations are possible with the hydraulic harness off, but care must be exercised. It is possible to lower below level, which can result in row unit ground strikes and dragging.

Switch Positions

PARK All solenoid valves are powered off and are

spring-loaded to ﬂow-open positions.

Use this position only for parking, to save tractor battery power. With the switch in PARK, any hydraulic ﬂow to the fold/lift circuit may have undesired results.

FOLD UNFOLD

FIELD Outer wings locked.

Full fold and unfold sequence is controlled. Down-pressure is disabled.

During unfold, the inner wings unfold before the outer wings. During fold, the outer wings fold before the inner wings. Fold range from fully folded to wings level (excepting down-pressure) is available.

Inner wing fold restricted to “gull wing”. Down-pressure available.

Use this position in the ﬁeld. It engages the down-pressure circuit for weight transfer. It provides a partial fold for extra wing clearance in ﬁeld turns.

Applicator Locks

The Nutri-Pro® NP4000 Applicator is equipped with several lock systems, which provide safety and/or operational functions. Manual locks require operator intervention for speciﬁc tasks. Automatic locks require no intervention, but you may need to be aware of their function.

Lift-Assist Lock Channels

Refer to Figure 22

These 11 inch (28 cm) length manual lock channels are installed on the rear lift-assist cylinders for adjustments, transport, parking, storage and raised servicing. The locks are held in place by a bent pin .

Fully raise the applicator (page 51) to install or remove the channels at the cylinder rods.

When not in use, the channels are stored on tubes on the caster side faces.

Wing Lock Pins

Refer to Figure 23

These pins are manually inserted after fold, both as a safety precaution, and to minimize wing-cradle impacts during transport.

When not engaged, the pins are stored in tubes at the base of the rest weldment.

See “Folding” on page 58.

Figure 22

Lift-Assist Cylinder Lock Channel

32373

Outer Wing Fold Latches

Refer to Figure 24

These latches are automatic, and should never require operator action. The latches couple the outer wing to the inner wing when folded, preventing movement of the outer wing during transport (the two outer wings might otherwise be able contact each other in unusual circumstances).

When unfolded, the latch pivots out and down (disengaged). During fold, the outer wing folds ﬁrst, until the stop posts contact each other. As the inner wing then folds, and passes vertical, the latch swings into engagement on the pins of the outer wing stop post.

At the start of unfold, the latches restrain the outer wings, causing the inner wings to unfold ﬁrst. As the inner wings near the ground, the latches fall away, allowing the outer wings to unfold.

Solenoid Valves

See “Fold/Lift Circuit” on page 49 for functions controlled by solenoid valves.

Raising/Lowering Applicator

Operate the tractor hitch in “position” or “depth” control mode, regardless of applicator hitch type.

The applicator may be raised and lowered while folded.

Raise For Transport (Folded)

These steps presume an applicator parked or stored folded, already raised, but on lift-assist locks and parking stands. No use of the applicator hydraulics is required.

1. Verify that lock channels are installed on the

lift-assist cylinders (page 50).

2. Verify that wing lock pins are installed on the folded

wings (page 50).

3. Raise the tractor 3-point hitch just enough to lift the

parking stand bases off the ground. Set the hitch circuit to Neutral. Shut off the tractor.

4. Raise the parking stands (page 42).

Note: The FOLD / FIELD switch may be in any position

for lift while folded.

Gradual Crushing Hazard:

Do not rely on hydraulic pressure alone to keep the applicator raised. Use parking stands (page 42) and locks (page 50) when working around a raised applicator. The tractor hitch may settle.

Equipment Damage Risk:

Do not fully fold or fully unfold while lowered. Perform complete fold and unfold only when fully raised. When lowered, the wing coulters near the wing pivots may be damaged by bending or ground dragging.

Lower While Folded

These steps presume that the intention is parking or storage, on lift-assist locks and parking stands.

1. Verify that the lift lock channels are installed on the lift-assist cylinders (page 50).

2. Verify that the wing lock pins are installed. Wings unfold during lower if these pins are not in place.

Tip-Over and Crushing Hazard:

Never unhitch without using parking stands, particularly while folded. A folded applicator without parking stands deployed may tip forward immediately upon unhitching. Anyone at the hitch or in the tractor could be seriously injured or killed. The tractor cab may be crushed.

3. Extend the fold/lift circuit to lower the lift-assist cylinders onto their locks.

4. Raise the tractor three-point hitch until the applicator mainframe is level front-to-rear, or the front is slightly higher than the rear. Set the hitch circuit to Neutral. Shut off the tractor.

5. Deploy the parking stands. Pin them so that the frame will be level when lowered onto the stands.

6. Start the tractor. Lower the tractor hitch until the applicator is supported by the parking stands.

Equipment Damage Risk:

Although it is possible to fully lower the applicator while folded, this is not recommended. This can place the full weight of the machine on the center coulters, exceeding their spring capability.

Note: If wing lock pins are installed, the FOLD / FIELD

switch may be in any position for lowering while folded.

Lower While Unfolded

These steps presume that the applicator is presently folded with lift-assist lock channels installed, and parking stands deployed, and that the intention is to park, store or service the applicator. For ﬁeld lower and ﬁeld adjustments, see topic “Field Lower” following.

1. Perform a Lower While Folded operation (page 54).

2. Set the lift/fold/circuit to Neutral or Float.

3. Remove the wing lock pins (page 50).

Refer to Figure 29

4. Set the FOLD / FIELD switch to

FOLD / UNFOLD

This arrests unfolding at wings-level.

5. Extend the fold/lift wing to unfold the wings, until wings-level.

6. To keep all coulters off the ground when unfolded and lowered, crank the gauge wheels to full extension (page 91).

7. If the tractor hitch is raised, lower it until the applicator rests on the parking stands at front.

8. Set the FOLD / FIELD switch to

FIELD

This allows the wings to move below level.

9. Extend the fold/lift wing to further unfold the wings until the gauge wheels touch the ground, then set the circuit to Float (to relieve pressure at hitch hoses).

Note: The counterbalance valve holds the inner wings at

their current position.

Field Lower

These steps are for lowering in the ﬁeld after initial line-up and after turns. Lift-assist lock channels (page 50) are presumed to have been replaced by spacers (page 43). The down-pressure/weight transfer system (page 92) is presumed to be adjusted.

The key objectives for an optimal lowering are:

• avoid side loads on coulter discs or tines by avoiding lowering with drooped wing tips, and

• avoid tine plugging by avoiding any reverse motion of the tines at the ground.

Being in slow forward motion during lower avoids both of these risks. The following instructions presume a lowering while stationary.

Figure 30

Switch for Field Lower

34918

Refer to Figure 30

1. Verify that the FOLD / FIELD switch is set to

FIELD

2. Check that wings are partially folded in ﬁeld lift, or at

least level. If they are drooping, retract the fold cylinders to correct.

3. Lower the tractor 3-point hitch to the preset ﬁeld

height. Set the hitch circuit to Position or Depth Control.

4. Extend the fold/lift circuit to lower the wings below

level into down-pressure mode, and to retract the lift-assist cylinders to their spacers.

Note: You may lower the hitch and lift-assist

simultaneously, but avoid lowering the lift-assist before the hitch.

5. Pull forward.

6. Leave the fold/lift circuit active in the lower/unfold

position, to supply oil to the down-pressure system.

Unfolding and Folding

Unfolding (At Field)

These instructions presume the applicator has just completed transport, is raised, and transport locks are installed. It is being unfolded for ﬁeld use.

1. Remove the wing lock pins (page 50).

Refer to Figure 31

2. Set the FOLD / FIELD switch to FOLD / UNFOLD.

3. Extend the fold/lift circuit to unfold the wings

4. Retract the fold/lift circuit slightly to raise the lift-

assist off the lock channels.

5. Set all circuits to Neutral. Shut off the tractor.

6. Remove the lift-assist lock channels (page 50).

Install the spacers (page 43).

7. If wing gauge wheels were extended, crank them to

ﬁeld height (page 91).

8. Lower the hitch to ﬁeld height.

Notes about normal unfold:

• Inner wings unfold ﬁrst. The outer wings are

constrained by the wing latches (page 50).

• Outer wings unfold last. The wing latches release just

before the inner wings are level.

• Wings do not unfold to below wings-level.

7. Extend the fold/lift circuit to unfold the wings.

8. Set all circuits to Neutral.

9. Shut off the tractor.

10. Unless using blocks or stands under wings, fully extend wing gauge wheels (page 91).

11. Deploy parking stands at desired or maximum height.

12. Start the tractor. Lower the 3-point hitch until the applicator rests on the parking stands at front.

13. If wings stop above horizontal, move switch to FIELD position, and Extend fold/lift to further unfold.

14. Extend until the gauge wheels contact the ground or the wings stop. Set the fold/lift circuit to Float.

Notes about normal unfold:

• Inner wings unfold ﬁrst. The outer wings are

constrained by the wing latches (page 50).

• Outer wings unfold last. The wing latches release just

before the inner wings are level.

• Wings do not unfold to below wings-level.

Machine Damage Risk:

Set the switch to UNFOLD. If set to PARK or FIELD, the wings may unfold to below level and drag inward on the ground.

Folding

These instructions presume that the applicator is unfolded and lowered.

1. Verify that the wing lock pins (page 50) are not in the wing rest cradles. Typically they are in storage tubes.

Refer to Figure 35

2. Set the Fold switch to

FOLD / UNFOLD.

Refer to Figure 37

Electrocution and Overhead Collision Hazards:

Do not fold with switch in FIELD position. In FIELD, the outer wing sections cannot fold. The folded applicator would

Switch for Fold

34918

be over 21 feet (6.2 m) high. This dramatically increases the risk of electrocution from overhead lines, with or without direct contact. It is also too high for safe transport.

Refer to Figure 36

3. Raise the hitch.

4. Retract the fold/lift circuit to simultaneously raise and fold the applicator. Observe the fold sequence. Lift and fold do not start and end at the same time.

If an abnormal fold is detected, set the fold/lift circuit to Retract, then Neutral at wings level. Troubleshoot the problem.

Transport

Loss of Control Hazards:

Never transport a 2-point applicator unless the tractor is properly ballasted to provide adequate weight on the steering wheels. A heavy 2-point applicator can dangerously reduce steering control. Check your tractor manual for ballasting requirements. A normal turn could result in an accident and serious injury or death.

Do not transport applicator with material in on-board tanks. Add liquid fertilizer at ﬁeld. Full tanks add 7200 pounds (3270 kg) to the weight of the applicator, almost all of it borne by the tractor 2-point hitch. This can substantially reduce tractor steering and does increase braking load. The applicator rear casters are free to swivel, and cannot provide protection against under-steer in turns.

Loss of Control Hazard:

Never use the applicator to tow a nurse tank on public roads. Tow the tank to the ﬁeld with a separate vehicle. The applicator cannot provide sufﬁcient lateral control of a trailing cart at highway speeds. The total weight of the train can also easily exceed the steering and/or braking capability of the tractor. A tank upset could occur during normal highway maneuvers. The resulting accident or spill could cause serious injury or death.

Braking and Loss of Control Hazard:

Do not exceed 20 mph (32 kph).

Loss of Control Hazard:

Never tow a 2-point applicator that weighs more than 67% of the tractor (transport tractor must weigh at least 150% of applicator). Ensure that the towing vehicle is adequate for the task. Using an inadequate tow vehicle is extremely unsafe, and can result in loss of control, serious injury and death.

Tractor weight matters. For ﬁeld conﬁguration (after transport), tractor must weigh at least 150% of the loaded applicator plus any loaded nurse tank. This tractor weight requirement is substantially higher than for transport.

Transport Steps

Know your applicator weight. See page 59 for a list of approximate weight of various conﬁgurations.

If tractor capabilities are marginal, check actual weight of applicator at a scale.

1. Check that fertilizer applicator is securely hitched to a sufﬁcient tractor (page 37)

2. Verify correct operation of lights.

3. Raise fertilizer applicator (page 52).

4. Install lift cylinder locks (page 50).

5. Fold applicator if unfolded (page 56).

6. Plan the route. Avoid steep hills.

7. Always have lights on for highway operation.

8. Do not exceed 20 mph (32 km/h). Comply with all national, regional and local laws when traveling on public roads.

9. Remember that the fertilizer applicator may be wider than the tractor. Allow safe clearance.

10. Transport slowly over uneven or rough terrain.

Final Applicator Setup

Prior to hitching nurse tank and/or loading materials, make and check ﬁnal applicator adjustments. This could include:

• Coulter (Option) depth and castering, page 86.

• Tine condition.

• Sealer adjustments (NP4000A), page 87.

• Application depth, page 89.

• Application Rate, page 95.

• Row cleaner adjustments, page 88.

• Make a dry run to check applicator functions, running

depth and sealing.

For nurse cart hitching, the applicator may be raised or lowered, folded or unfolded. However, raised and folded hastens departure if any nurse tank problems are discovered before cart hitching.

NH3 Operations

Operations for convention liquid fertilizer begin on page 74.

NH3 Nurse Tanks

Use nurse tanks with proper current safety certiﬁcation, and current safety equipment and features.

Consult with your anhydrous ammonia supplier for safety information and correct safe handling, transport and use of anhydrous ammonia.

Consult with local and regional authorities on safe and legal use of anhydrous ammonia, including emergency and environmental contacts, and release reporting requirements.

Review any decals and manuals available for your nurse tank cart, and for any of its components. There may be separate manuals for the tank, running gear, indicators, valves and ﬁttings.

This (Nutri-Pro® applicator) manual covers typical operations for a representative NH3nurse tank cart. Your cart is likely to vary. See the “Using Anhydrous Ammonia Safely” manual (407-551M) for further information about nurse tank carts.

NH3: Check Hydrostatic Relief Valves

3. Check that the plastic cap is in place at each valve. In the Great Plains conﬁguration, this would be:

A23

• at each cooler

A15

• at the outlet side of the breakaway coupler

A15

Ammonia Exposure and Loss Hazards:

Understand the reason for any lifted or missing hydrostatic relief valve caps. If a cap is out of place, that line section may have been closed with liquid NH3 present, which later vented, dislodging the cap. It is also possible that the valve disc has deteriorated and is venting at normal operating pressures.

NH3: Close Bleed Valves

4. Put on goggles and gloves. Approach the applicator from up-wind.

5. Check that all bleed valves are closed:

A29

• at the pressure/temperature gauges.

A16

• at the outlet side of the breakaway coupler.

A13

• at the inlet side of the breakaway coupler.

NH3: Check Hose Discharged

6. Visually check the general condition of the breakaway connection . If the two halves appear mated, use the inlet side bleed valve for the next step. Otherwise treat this as a breakaway event (page 71).

7. Orient the bleed valve oriﬁce so that it points away from you and down-wind.

8. Wearing rubber chemical gloves, slowly open the bleed valve by rotating the T-handle

A13

counter-clockwise.

A14

A13

Figure 40

Hydrostatic Relief Valve

Possible Chemical Hazard:

Wear your NH3 PPEa. On a connection, residual NH (possibly in dangerous quantities) may be present in the applicator systems, from the inlet Acme cap to the tines. NH could also be present in dangerous quantities between the Acme cap and the cart shutoff valve. Unprotected exposure could result in permanent lung/eye injury or death.

a. PPE: Personal Protective Equipment

31564

A18

A13

Check for signs that there may be residual NH3 in between the Acme cap and the shut-off valve:

• strong ammonia odor

• hissing of escaping gas

• valve getting cold

• dripping or spraying ﬂuid

9. If there are any signs of residual NH3, leave the

A14

bleed valve open until the ammonia has vented, and the inlet ﬁttings have re-warmed to ambient temperature. This could take tens of minutes if the applicator was recently and improperly shut down.

10. Close the bleed valve.

NH3: Hitching Nurse Tank

Consult with the nurse tank supplier, and all available nurse tank documents, before hitching for the ﬁrst time.

NH3: Possible Chemical Hazard:

Clear all non-essential personnel from the area at this time. Take normal NH3ﬁeld precautions. Although ammonia release is not expected for mechanical hitching, the tank could be venting small amounts, or large amounts if mis-conﬁgured, or if a component fails. On a re-hitch, the applicator may also be venting residual material. Unprotected exposure could cause serious lung or eye irritation.

Hitch a nurse tank to the applicator only at the ﬁeld, and not prior to transport.

If taking delivery of a tank at the ﬁeld, complete an inspection (see “Using Anhydrous Ammonia Safely” manual (407-551M) before accepting the tank.

NH3: Mechanical Cart Hitching

1. Spot the applicator. Three objectives are:

All tank carts:

• Spot to avoid reverse moves after cart hitching.

• Face the tractor and applicator basically up wind, but with a cross-wind component such that:

• the hose connection(s) and valve operations will be made down-wind of where you stand for those operations.

Refer to Figure 53

2. Bring the applicator rear hitch tongue and nurse tank cart tongue into close proximity (a few inches).

3. Push down on the red tongue release handle .

This frees the applicator rear hitch tongue to extend 7 inches (17.8 cm) to the rear, and 9 inches (23 cm) to either side, to assist with cart tongue alignment.

4. Align the cart clevis hitch with the applicator pull bar. Insert and secure the 1 inch hitch pin.

5. Securely attach the cart’s safety chains to the hitch chain anchors .

6. Optionally re-seat the applicator rear hitch tongue, at this time, by using the tractor to move the applicator backward several inches, until the latch on the hitch re-engages.

A11

Anhydrous Ammonia Exposure Hazard:

Do not skip step 1. Wear your PPEa. Never open a line without ﬁrst performing a bleed to check it. If the applicator was improperly shut-down, the hose can contain more NH3 than your PPE can handle. Lung damage, burning, blindness and death are possible.

Refer to Figure 43

2. Check that the two halves of the breakaway coupler are ﬁrmly mated at the swivel bracket. If not, see the Squibb-Taylor Flo-Max™ manual for re-connection instructions.

3. Check that the break-away coupler bracket is free to swivel, relative to pointing directly rearward horizontal, by at least: 80° to each side, 45° up, and; 20° down.

4. Remove, the Acme cap on the inlet side of the break-away coupler.

Refer to Figure 44

Blinding, Choking and Respiratory Hazard:

Never look directly into an ammonia hose or ﬁtting. Use a mirror. Always assume that ammonia is present in the system. There are many ways it can hide, and surprise you later. See “Avoid Trapped Anhydrous” on page 116.

6. Using a hand mirror, inspect the gasket inside the

A12

ﬁtting . If there is no sign of ammonia, and no odor, you can remove the gasket by hand for closer inspection.

This gasket makes the liquid-tight seal between the hose and break-away coupler. Inspect it for a smooth face, no cracks, chips or weathering, and no sign of permanent compression. Replace gasket as needed for a tight seal.

debris or other contamination.

Refer to Figure 45

11. Route the cart hose along the cart tongue, securing it to any clamps or caddies provided.

Do not clamp or tie the hose within 3 feet (92 cm) of the breakaway coupler inlet .

A12

Allow at least 13 inches (33 cm) slack in the hose within the ﬁrst 3 ft. Do not allow excess slack that could allow the hose to snag or drag on the ground.

12. Bring the hose outlet and applicator inlet

A57 A12

into contact. Hand tighten the swivel collar or shroud on the hose ﬁtting. Do not use tools. You only need to adequately compress the gasket in the applicator inlet.

NH3: Dry Run

Before activating the NH3delivery, cautious practice is to make one dry run pass, including a turn in each direction. This assures that tine depth is set correctly, hydraulics are working correctly, the nurse tank cart is tracking without issue, proper slack exists for all hoses and harnesses, and the meter console is reporting correct ﬁeld speed.

NH3: Pass Planning

If ﬁeld requirements permit, you can minimize exposure to NH3 vapor with the following recommendations:

Refer to Figure 46

• Check the wind direction.

• Plan passes to be cross-wind and turns up-wind.

• Plan ﬁrst pass on down-wind side of ﬁeld.

• Choose your ﬁrst pass to allow you to be up-wind while operating valves at the nurse tank and applicator. Opening the emergency shut-off valve

A18

typically requires climbing on the applicator from the right. Starting with the wind from the right is optimal.

WIND

Anhydrous Ammonia Exposure Hazard:

If ﬁeld requirements result in any down-wind operations:

▲ Use only a tractor with an enclosed cab.

▲ Have an escape route (up-wind turn) available for all

down-wind operations.

▲ Conduct end-of-pass operations to minimize above-ground

releases.

▲ Be mindful of the risks of olfactory fatigue. You can

“get used to” the odor and fail to notice when concentrations get dangerously high.

NH3: Start of Pass Planning

Ideally, you want NH3 to begin ﬂowing out of the tines right at the start of a pass, with the tines already in the ground. This minimizes atmospheric releases.

Depending on wind direction, tractor capability, available headlands, and ﬁeld conditions, there are several ways to start each pass.

A. Capable Tractor:

Lower applicator into ground at start of pass. Pull forward to set them to operating depth. Start meter ﬂow. Do not start moving until ﬂow divider pressure gauge nears typical operating value.

B. Headlands Available, Any Tractor:

Lower applicator to ground some distance ahead of the application area. Move forward slowly. As tines enter ground, start meter ﬂow.

C. No Headlands, Marginal Tractor:

Lower applicator to ground at start of pass. Start forward movement, then meter ﬂow. Move slowly until console rate display nears target rate.

instructions or checklists. They are outlines for planning pass starts. See the step details starting on page 79 and the checklists on page 82.

NH3: Monitor Operation

Refer to Figure 47

The optional SCS 450 console monitors NH3 ﬂow, monitors ﬁeld speed, and operates the (rate) control valve to deliver anhydrous ammonia at your desired rate.

Once setup for the applicator and preferences, and conﬁgured for the rates/limits, the monitor is typically used in the “RATE 1” or “RATE 2” FLOW CONTROL modes.

POWER: must be ON

FLOW CONTROL: as desired

BOOMS: 1 or 1, 2 and 3 ON, all others don’t-care (suggest OFF)

MASTER: OFF except when in ﬁeld and in ground

POWER Switch: Ammonia Release Hazard:

The MASTER switch only controls the On/Off valve if the

A31

POWER switch is ON (and power is supplied to the console). If you turn the POWER switch off with the MASTER and BOOM 1(2 and/or 3) switch on, the On/Off valve(s) remain OPEN, the Control Valve retains its setting, and

NH3: Possible Chemical Hazard:

Anhydrous ammonia is now ﬂowing into the ground. Some routinely escapes to the atmosphere. Check for leaks. Take action if strong odor is detected or a leak seen. Turn up wind. Turn off ﬂow. Check gauges from tractor cab. Engage emergency shut-off valve if a leak is detected.

Minor odor during application is normal, particularly if the tractor cab is ever down wind of recent passes.

Strong or irritating odor indicates a problem. Conditions may not be suitable for application (soil too dry, cloddy and deeply cracked, for example), or there may be a system problem.

a. This 5 psi correlation is only true under no-ﬂow conditions. When NH3 application begins, the pressure reading at the cooler gauge

drops, due to the reduced temperature of the cooled ﬂuid, and pressure losses due to ﬂow in plumbing.

NH3: Field Turns

a. Before the turn,

set the MASTER switch OFF. Leave the applicator in the ground, and continue forward movement.

b. Lift the applicator (page 51) at the turn point.

Major Spill / Equipment Damage Hazards:

Do not turn too tightly. The nurse tank could strike the applicator, be upset, and leak. On 2-Point and Pull-Type, the nurse tank tongue could strike the caster tires. On 3-Point, the

Ammonia Vapor Release Occurs at Turns:

Avoid down-wind turns. Do not raise for turns if unprotected individuals or sensitive livestock are immediately down-wind of the turn. Stop instead.

nurse tank tires could strike sealers or tine shanks.

c. Turn up-wind for the next pass.

d. Line up per your start of pass plan.

e. Lower the applicator into the ground.

Turning off NH3 ﬂow prior to raising for turns does deplete some of the liquid ammonia in the delivery lines, but not all of it, and considerable vapor remains. At turns, there will be some release of NH3vapor, and possibly some NH3liquid. Be prepared for it. Minimize exposure to yourself and others.

f. Set the MASTER switch ON.

g. Pull forward and complete the pass.

Turn up-wind immediately if a hazardous concentration of fumes reaches the tractor cab.

b. Suspend application per “NH3: Suspending

Application” on page 69.

c. Put on your chemical gloves.

Be wearing your goggles.

d. Carefully approach the nurse tank from up-wind.

Expect some ammonia odor, but if it is extremely strong, there may be an above-ground release in progress due to malfunction or part failure. If so, remain clear until the release subsides.

e. When safe to do so, shut off the nurse tank

withdrawal valve .

A65

f. Re-enter the tractor cab.

g. Turn MASTER switch ON.

h. Resume ﬁeld application until reported rate begins to

fall. Increase rate to maximum (to fully open Control

A30

Valve ).

i. Continue ﬁeld application until both cooler and

divider pressure gauges read zero.

j. Facing into the wind, raise the applicator and stop.

Ball Valves: Trapped NH3 Hazard:

Avoid routinely closing ball valves (other than the nurse tank withdrawal valve) with liquid NH3 in the lines. Fluid is trapped in the line above the valve, may trigger relief valves, and can get trapped inside the valve ball unless it has a bleed port (not yet common on nurse tank hoses). See “Avoid Line Traps” on page 116 and “Avoid Ball Traps” on page 117.

A typical ball valve can trap enough NH3 to make a room the size of a two-car garage uninhabitable (concentrations above IDLH in moments). When the ball valve is later opened, while warm, the NH3 is expelled at high pressure. If the line is pointed at your face, you could receive a fatal exposure.

k. Set the MASTER switch to OFF.

l. Wait at least 1 minute for row line vapor to dissipate.

m. Turn so that the wind is directly from the right.

n. Open all bleed valves. Standing up-wind of each,

and making sure oriﬁces point away from you, slowly open bleed valves at:

• nurse tank hose inlet end

• nurse tank hose outlet end

• breakaway valve ( or , whichever is safer)

A13 A16

• cooler temperature gauge .

A61

A29

o. Close all remaining operating valves:

• nurse tank hose inlet end

• nurse tank hose outlet end

• emergency shut-off valve .

A60

A18

p. Wait at least one hour before moving applicator to

any spot near unprotected people or livestock. It will continue to out-gas ammonia vapor for some time.

NH3: Breakaway Event

Initially treat a breakaway coupler separation event as you would any other ﬁeld emergency. Perform the steps at “Ammonia Emergency Action” in the “Using Anhydrous Ammonia Safely” manual (407-551M). Only then consider performing the steps on this page.

Although the breakaway coupler is designed to separate, such breakaways are not routine events.

Upon a breakaway, what to do about the breakaway coupler itself is the last consideration. Priorities are:

1. Protect: Perform basic ﬁeld emergency action, which may included summoning emergency responders if a major release is in progress, or the nurse tank is tipped over, or is otherwise at risk of a major release.

2. Assess: If the nurse tank appears intact, sound and stable, determine the cause of the breakaway. It is unlikely to be something simple that will allow a timely re-coupling and resumption of application.

If, and only if, the nurse tank is safe to approach, take the next steps to discharge both sides of the breakaway.

Discharge Applicator:

3. Perform the steps at “NH3: Stopping Application” on page 70. Remain up wind and clear of nurse tank while doing this.

4. With the oriﬁce pointing away from you, and down-wind, slowly open the coupler bleed valve

A16

at the applicator half of the breakaway coupler(s). If you closed the emergency shutoff(s) after breakaway, each bleed will release liquid NH3, under pressure, most likely as a spray.

Discharge Nurse Tank Hose(s):

5. Position the tractor and applicator near the nurse tank. Stop up-wind of the tank, but slightly cross-wind of the tank (so that you are not exposed to residual applicator fumes while working around the tank). Face the tractor into the wind.

6. From up-wind, approach the nurse tank.

7. Close the nurse tank withdrawal valve .

A65

8. From up-wind, approach the nurse tank hose outlet

A57

end .

9. Locate a bleed valve on the nurse tank half of a

A13

coupler. Be careful not to touch or loosen the Acme coupler . Bleed only one hose at a time.

A57

10. Position the outlet such that the bleed valve oriﬁce points both away from you AND points down-wind AND can be opened and left pointing that way unattended. If this is not possible, get expert help.

Upon Event: Probable Chemical Hazard:

A 60cc NH3liquid release to air has already occurred. Assume a major release is also in progress or imminent. Act accordingly. Request assistance from trained experts rather than risk blindness, disﬁguring/disabling injury or death.

A breakaway event is most likely due to a major equipment failure (such as nurse tank running gear fracture), or a gross operator error (such as towing/turning too fast, or departing level ground). These cases can result in an immediate serious spill, or result in a damaged tank at risk of leak at any time.

Even in the case of a basic operator error (such as movement with only the nurse tank hose connected) both applicator systems and nurse tank hose(s) at breakaway are fully charged with liquid NH3, right up to the checks in the breakaway halves. The nurse tank side is under full tank pressurization. The applicator hose(s) may be under pressure.

This was an unplanned event. Wind direction may not be favorable for discharging and re-coupling. If the wind is light

or calm, do not attempt to bleed the breakaway coupler halves. Your ﬁeld PPEa is not sufﬁcient for the releases

necessary.

11. Opening this bleed valve WILL release the substantial amount of liquid NH

presently trapped in

the hose, most likely as a spray. Open the valve very slowly, just until some ﬂuid appears. Leave the valve just slightly open.

12. Walk away, up-wind. Stay away until the release concludes. Carefully open bleed valve completely to conﬁrm hose is discharged. For dual-cooler, repeat step 9 through step 12 for the other hose.

13. Close all breakaway bleed valves ( x and ), and any nurse tank hose valves . Disconnect the

A13 A16

A60

nurse tank half of the breakaway coupler at the Acme coupler .

A57

14. Correct the cause of breakaway, only if trivial to do in the ﬁeld.

Before Re-connection: Elevated Exposure Hazard:

Exercise extreme care. Even if the nurse tank is undamaged, sound and upright, a breakaway event is not a normal re-hitch situation. A substantial NH3 bleed is required that WILL

release a ﬂow of liquid anhydrous ammonia under pressure. If the wind is calm or light, do not attempt to bleed the nurse tank hose(s). Your ﬁeld PPEa is not sufﬁcient.

15. Consult the breakaway manual for re-coupling instructions.

NH3: Unhitching Nurse Tank

The procedure is different for exchanging tanks vs. concluding application.

NH3: Exchanging Nurse Tanks

Consult with the nurse tank supplier, and all nurse tank documents, before unhitching or exchanging tanks.

a. Suspend NH3 application per “NH3: Suspending

Application” on page 69.

The purpose of this step is to minimize atmospheric NH3 vapor while working at the rear hitch, because you may not be able to conduct all unhitching and re-hitching steps from up-wind of all the tines.

b. Position the applicator cross-wind, with the wind

from the right, tines in ground.

c. Use the rope to close the emergency shut-off valve.

d. Put on your goggles and rubber gloves.

e. Shut off the nurse tank withdrawal valve . Leave

the nurse tank hose valves ( , if any), open.

A60

A65

f. From up-wind, and with the oriﬁce facing away from

you, slowly open the breakaway coupler inlet bleed

A13

valve .

g. Stand clear and wait for the hoses to discharge.

h. From the up-wind side, unscrew the nurse tank hose

outlet coupler . Secure the hose using whatever

A57

means the cart provides.

i. Close all opened bleed valves.

j. Release the nurse tank safety chains.

k. Remove the nurse tank hitch pin.

NH3: Final Nurse Tank Unhitch a. Conclude NH3 application per “NH3: Stopping

Application” on page 70.

Control Variation Hazard:

If you are using multiple nurse tanks, study each one separately. Unless they are owned by you, and known to be identical, there is a high probability that there are differences between them, even if they are all from the same terminal.

The purpose of this step is to minimize atmospheric NH3 vapor while working at the rear hitch, because you may not be able to conduct all unhitching steps from up-wind of all the tines.

b. From the up-wind side, unscrew the nurse tank hose

outlet coupler ( on page 29).

A57

c. Secure the outlet coupler with the nurse tank’s Acme

parking plug.

d. Close all opened bleed valves.

e. Release the nurse tank safety chains.

f. Remove the nurse tank hitch pin.

g. Remove nurse tank from behind applicator.

Liquid Operations

Operations for anhydrous nitrogen fertilizer begin on page 61.

Liq: Filling On-Board Tanks

The tanks may be loaded from the quick-ﬁll inlet, or from the lids (page 75).

If the fertilizer solution has any tendency to settle, sediment, gel, coagulate, precipitate or stratify, load material immediately prior to application. The tank system has no agitators for sustaining suspensions.

Apply fertilizer soon after material loading. Clean out unused materials promptly. Fertilizer allowed to remain in the tanks for an extended period can settle, resulting in excessive or insufﬁcient concentrations during application. System plugging can also occur.

1. Hitch the applicator to a tractor. Filling an unhitched applicator is not recommended, as it can increase parking stand loads above the bearing capacity of the soil.

2. Inspect the tanks from the lids.

3. Drain excess condensation from the tank, so that this water does not dilute the material to be loaded. See “Material Clean-Out (Liquid)” on page 128.

4. Flush the tank if there is other residue present.

Liq: Tank Quick-Fill

Refer to Figure 51 and Figure 6 or Figure 5 on page 29 or 28

5. Position the applicator on level ground, or tanks may ﬁll unevenly.

6. Connect the nurse-tank hose to the quick-ﬁll coupler located at the left end of the left tank. Lock hose in place with cam-lock levers.

7. Open the discharge valve ( , not shown) of each tank to be ﬁlled. If ﬁlling must be performed on unlevel ground, ﬁll one tank at a time.

8. Set the selector valve to “FILL” (handle arrow pointing forward, toward elbow from inlet).

9. Open shut-off valve at quick-ﬁll coupler.

10. Open any supply valve and ﬁll tanks. Tanks are marked with ﬁll levels.

11. Close valve at supply, then quick-ﬁll coupler, and disconnect the nurse tank hose.

12. Set selector valve to OFF, or to PUMP if applying immediately.

Agricultural Chemical Hazards:

Observe safety precautions speciﬁed by material suppliers. Some chemicals can cause serious burns, lung damage and death. Avoid contact with skin or eyes. Avoid prolonged breathing of chemical fumes. Wear respirator and other protective equipment as required by chemical manufacturer. Seek medical assistance immediately if accident occurs. Know what to do in case of an accident.

System Plugging Risk:

Use only pre-mixed liquid fertilizer. Fill tanks at ﬁeld, immediately prior to application. Do not use dry mixes. Do not leave material in tanks for extended periods.

Liq: Tank Lid Fill

Employ two persons for top ﬁll; one to secure the hose at the tank, the other to control a supply line shut-off valve.

These steps presume completion of step 1 through step 5 on page 74.

Refer to Figure 52 and Figure 6 or Figure 5 on page 29 or 28

13. Close selector valve (or set to PUMP; there is no

L15

risk of material leakage through the boom until the pump is operating).

14. Open both tank discharge valves to the selector

L13

valve, if cross-ﬁlling from one tank to the next is desired.

15. Open the lid of the tank to be ﬁlled.

L12

Chemical Hazard - Tank Lid:

For top loading, wear gloves and any other protective equipment indicated for any materials that have ever been used in the tank (not just the materials recently loaded or presently being loaded). Normal operations splash material on the underside of the lid. It is likely to be coated with residues that could be highly concentrated, whether dry, damp or wet. Remove the lid slowly to avoid throwing off material toward yourself.

The tank lid completely unscrews for a 7 in (18 cm) opening.

16. Insert the supply hose.

17. Open the supply line valve. Monitor tank level. Fill to desired level. Close supply valve.

18. Remove hose. Close and secure the tank lid. The lid has twin threads. Make sure that both are evenly engaged when tightening the lid, and that the lid is fully seated.

Liq: Hitching Conventional Nurse Tank

Hitch a nurse tank to the applicator only at the ﬁeld, and not prior to transport.

Liq: Mechanical Cart Hitching

1. Spot the applicator to avoid reverse moves after cart hitching.

Refer to Figure 53

2. Bring the applicator rear hitch tongue and nurse tank cart tongue into close proximity (a few inches).

3. Push down on the red tongue release handle . This frees the applicator rear hitch tongue to extend 7 inches (17.8 cm) to the rear, and 9 inches (23 cm) to either side, to assist with cart tongue alignment.

4. Align the cart clevis hitch with the applicator pull bar. Insert and secure the 1 inch (2.6 cm) hitch pin.

5. Securely attach the cart’s safety chain(s) to the hitch chain anchor(s) .

6. Optionally re-seat the applicator rear hitch tongue, at this time, by using the tractor to move the applicator backward several inches, until the latch on the hitch re-engages.

Liq: Making Nurse Tank Connections

1. Close shut off valves on all hoses of both tank and applicator .

2. Route tank supply hose to applicator inlet . Allow ample slack for tight ﬁeld turns and uneven ground. Do not leave so much slack that the hose can reach the ground.

3. Remove plug from applicator inlet, and any cap on tank supply hose.

4. Inspect and clean connector ﬁttings.

5. Mate connectors of tank and applicator supply hoses. Fold cam levers forward to lock. Leave valves closed.

6. If the tank has additional hoses, secure them at the tank.

7. Check ground drive sprocket setup (page 103).

8. Set rate on pump adjuster dial.

Refer to Figure 6 on page 29 or Figure 5 on page 28

9. If relief valve has not been previously adjusted, perform initial setting per page 103.

Liq: Prime the Ground Drive System.

10. Wearing gloves, manually rotate the ground drive wheel until material appears at the tines.

Begin ﬁeld operations.

The pump automatically operates when the applicator is lowered to ground contact and in motion. The pump automatically stops when the applicator is raised for turns.

L25

Liq: Hydraulic Drive Start-Up

Prior to ﬁrst use, determine the hydraulic remote circuit ﬂow rate setting per the procedure on page 105.

4. Set console MASTER switch OFF.

5. Set console POWER switch ON.

6. Select FLOW CONTROL RATE1 or RATE2 as desired, and verify rate setting.

7. Set console BOOMSa switch 1 ON.

8. Set the ﬂow rate for the hydraulic remote circuit as established by the procedure on page 105.

9. Activate the circuit by moving the lever to Retract. You may hear the pump operating, but with the MASTER switch off, no material ﬂows to rows.

10. Set the MASTER switch ON. Check for material ﬂow at the tines. Prime second hydraulic pump as required.

11. Begin ﬁeld operations. Monitor the fertilizer pressure gauge (or PSI display on optional console).

Liq: Field Operations (Either Pump)

12. Monitor the fertilizer manifold pressure (gauge or PSI display on optional console).

13. Mind the fertilizer tank levels while planting, both to: a. conﬁrm expected consumption rate, and; b. avoid running the pump dry.

14. If residual fertilizer is not recovered at end of planting, apply it to the last ﬁeld planted.

15. Clean out fertilizer system per page 128.

Sharp Object Hazard:

Ground Drive: Exercise caution when near and handling the ground drive wheel. Wear gloves. The tines may be sharp.

Equipment Damage/Material Misapplication Risks:

Ground Drive: Do not run the pump dry. With all drive chains in place, the ground drive pump always runs when the applicator is lowered and in motion. Air rapidly damages the pump. Keep ﬂuid in pump at all times. Disconnect a chain when not applying fertilizer.

Hydraulic Drive: Do not run the pump dry. The pump runs when the remote circuit is active, regardless of applicator status. Air can damage the pump. Keep ﬂuid in the pump at all times. Set remote to Float when not applying fertilizer.

If fertilizer is exhausted prematurely, reload fertilizer immediately. If fertilizer is not available, load clean water, continue planting with pump operating (to ﬂush system), and disconnect pump drive before water is exhausted (to keep pump wet).

Liq: Pauses and Turns

Ground Drive Pauses and Turns

When the applicator is stopped, or lifted, the pump stops. The boom is still pressurized, but this bleeds down to 8 psi very quickly (seconds), at which point the nozzle clamp check valves close off ﬂow to the rows.

Hydraulic Drive Pauses and Turns

If the applicator has the optional hydraulic drive system, pauses cause the speed sensor to report zero speed, which causes the console to close the ﬂow control valve. Set the pump hydraulic remote to Float if stopping for and extended period.

For turns and ﬁeld moves, set the MASTER switch OFF to avoid material loss. If the factory conﬁguration of the plumbing has been modiﬁed for section control, use the BOOM switches as desired for point row applications.

a. The standard conﬁguration uses only Valve 1. If optional section control is installed, also engage BOOMS switches 2 and 3.

Liq: Fertilizer Operation

For an aftermarket pump system, consult the pump or system documentation. These pages describe the available Great Plains systems. See page 28 through page 34 for callout references.

Liq: Ground Drive Operation

The piston pump is ground driven. When the applicator is lowered and in motion, the pump operates, and fertilizer is applied based on the drive Range sprocket, and pump adjuster dial setting .

Liq: Hydraulic Drive Operation

The centrifugal pump is driven by an integrated hydraulic motor. The output of the pump is under pressure whenever the hydraulic motor circuit is activated. Rate is regulated by a ﬂow control valve , and monitored by a ﬂow meter , both connected to a Raven SCS 450 console (or other compatible Raven console).

Liq: Boom Operation

The liquid fertilizer boom system is designed to operate (ideally) between 15 and 40 psi. Several system elements affect system pressure, and need initial setup, periodic maintenance, and adjustment.

Liq: Start-Up Preparation (Either Pump)

1. Check that ample fertilizer has been loaded into the tanks. The liquid level must be higher than the hydraulic pump for pump priming. Close and cap or plug any tank ﬁll inlet valves (such as in the Great Plains plumbing system).

2. Check that tank valves (such as discharge, transfer, selector) are conﬁgured and ready for use. In the Great Plains tank plumbing system, this would be:

L13

tank discharge valves open to selector valve

L15

selector valve open to tanks and pump

3. On suitable ground, raise the applicator.

Possible Agricultural Chemical Hazard:

Avoid contact with skin or eyes. Wear proper protective equipment as required by chemical manufacturer. Avoid prolonged breathing of chemical fumes. Wear respirator as required by chemical manufacturer. Some chemicals will cause serious burns, lung damage, and death. Seek medical assistance immediately if accident occurs. Know what to do in case of accident.

Pump No-Flow Risk:

The hydraulica pump must be primed. The liquid level in the tank must be at a higher elevation than the pump inlet. The top of the pump must be ﬁtted with either an air bleed line to the top of a tank, or a manual bleed valve. The bleed line must be open at least until the pump if ﬁlled with material.

When tanks and pump are ordered, the factory conﬁguration includes an air bleed line from the hydraulic pump to one of the tank lids. User-conﬁgured systems must make provision for pump priming.

a. The ground drive pump is a positive displacement piston

type, and normally self-primes at any liquid level.

417-199M Table of Contents Index 2014-05-14

Page 83

Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 79

Liq: Monitor Operation (Option)

Refer to Figure 54

With the optional hydraulic drive pump, the optional SCS 450 console monitors fertilizer ﬂow, ﬁeld speed, and manifold pressure. It operates the control valve to deliver fertilizer at your desired rate.

Once setup for the applicator and preferences, and conﬁgured for the rates/limits, the monitor is typically used in the “RATE 1” or “RATE 2” FLOW CONTROL modes.

Liq: Starting Application with Console

1. Enter the tractor cab.

Refer to Figure 54

2. At the console, set the POWER switch ON.

3. Set the MASTER switch to ON.

4. Set the BOOMS 1 or BOOMS 1,2&3 switcha on to ON all others don’t-care (suggest OFF).

5. Select the desired RATE preset.

6. Engage the remote for the hydraulic drive pump. Advance lever to preset for +35% of desired rate.

7. Lower applicator to operating depth (if not already lowered) and begin ﬁrst pass.

See SCS 450 manual for monitor operation details.

Suspending Application

With the hydraulic drive pump option, material continues to ﬂow if the implement is raised while in motion. To conserve material and prevent unintended application, set the MASTER switch to OFF when raising.

When stopping, operating the MASTER switch is not usually necessary, if the console has an active speed sensor data source.

If suspending application for more than a minute, also set the pump motor hydraulic circuit to Float.

No console actions are required to suspend application with ground drive (preset or variable rate).

Figure 54

Typical Application Screen

Liq: Stopping Application

1. Ground Drive: If possible, plan ﬁnal passes so that they occur prior to tank run-out. This keeps the pump wet. If you do exhaust the material, reﬁll with water.

2. At completion of application, apply almost all of the remaining fertilizer on the last ﬁeld. Reﬁll the tank with clean water.

3. Set application rate to maximum to shorten the remaining steps:

• Ground Drive: Exchange the ground drive driving

sprocket to obtain High Range (page 103).

• Ground Drive: Set the pump dial to 10 (page 104).

• Hydraulic Drive: Set the console (Option) for

maximum rate.

Piston Pump Damage Risk:

When conﬁguring the ground drive pump for high rates, check the chart, slide chart or CDS-John Blue web calculator to determine the maximum ﬁeld speed that stays at or below the pump’s maximum rated rpm.

4. Apply the water to the ﬁnal ﬁeld to ﬂush system.

5. Close shut-off valves on both sides of all hose connections.

Liq: Unhitch Liquid Nurse Tank

6. Disconnect all tank-applicator couplers.

7. Disconnect the safety chains.

8. Remove the hitch pin. Move the trailer hitch off the applicator’s draw bar.

Adjustments

To get full performance from your NP4000/A/B fertilizer applicator, you need an understanding of all component operations, and many provide adjustments for optimal ﬁeld results. Some of these have been covered earlier in this manual.

Even if your planting conditions rarely change, some of these items need periodic adjustment due to normal wear.

Row Adjustments

Anhydrous Coulter Application Depth

Applies to model NP4000A/B only.

Refer to Figure 55

Tine release depth is set by tool bar height above the ground, coulter shank height and tine height .

Chemical Hazard:

Adjust height dry. Make adjustments before charging the metering system with anhydrous ammonia, or after thoroughly discharging the system. With the tines out of the ground, there could otherwise be releases of ammonia at dangerous concentrations.

Tool bar height is controlled by the tractor hitch in the center section. Wing tool bar height is set to match the center using a crank-assisted manual adjustment (page 91).

Tine height is adjusted at the mount . This requires adjustment as the coulter blades wear. Loosen the nuts on the U-bolts . Lower the shank and re-tighten.

Design coulter operating depth is 3 to 7 in (7.6 to 18 cm). Operation below 7 in (18 cm) is not recommended, as high rates of disc wear are likely.

Application depth is unaffected by the coulter spring (page 131) and sealer spring (page 87) settings.

Depth Reference Information

These are the factory settings.

Shank height below tool bar is:

Overall height of the tool bar base to coulter edge is:

329⁄32 in (79.5 cm)

At factory settings, NH3 is released from the tube at:

⁄8in (9.7 mm) above the lower coulter edge.

For a precise release depth, subtract this amount from the total coulter depth .

Anhydrous Coulter Castering

Coulters may be operated locked in-line, or with limited free castering.

Refer to Figure 56

To lock the coulter, loosen the jam nut at . Align the coulter front to back. Tighten the set screw at , then the jam nut.

To unlock the coulter, loosen the jams nut at . Loosen the set screw bolts at , then tighten the jam nuts.

Note: Do not loosen the stop bolts .

NH3 Sealer Adjustments

The standard NP4000A/B spider sealers have three adjustments. You may need to alter these from factory settings, based on soil conditions, crop residue and application speed.

Refer to Figure 57

1. Down-pressure: T-handles set the arm spring tension. The adjustment plates have 3 settings.

2. Spacing: The arm weldments have 8 bolt holes allowing 2 setback positions and 2 spacing positions.

3. Angle: The sealer mount plates have 4 holes: 2 in-line , and 2 extra holes , slightly offset, providing an angle adjustment.

These adjustments are most easily made with the applicator raised. The down-pressure adjustment may be made with rows in the ground, with some extra effort.

5 6

Chemical Hazard:

Adjust sealers with rows dry. Make adjustments before charging the metering system with anhydrous ammonia, or after thoroughly discharging the system. With the tines out of the ground, there could otherwise be releases of ammonia at dangerous concentrations.

Sealer Down-Pressure Adjustment

The following trip down-pressures are available. These values are per sealer arm, and are with the coulters in the ground, and arms slightly raised per nominal factory assumptions (as depicted in Figure 55 on page 86).

Note: With the applicator raised, position has minimal

spring tension.

Handle Slot Down-Pressure

Rear/Lowest 12 pounds 5.4 kg

Mid/Medium 17 pounds 7.7 kg

Forward/Max. 28 pounds 12.7 kg

Sealer Spacing or Setback Adjustment

For in-line (parallel) sealer wheel running, use the center

5 3

holes in the mount plates . In-line orientation is recommended for high-residue ﬁelds.

Sealer Angle Adjustment

10° of leading toe-out (20° total) is available by using the inner center hole of the mount plate and the leading offset hole . No setback adjustment is available when using toe-out. Toe-out is not recommended for high-residue ﬁelds.

Terra-Tine™ Adjustments (Option)

Note: All adjustments must be made with the applicator in

the fully raised position.

Refer to Figure 58

Excess Wear Risk:

Check that the Terra-Tine™ Row Cleaner tines DO NOT touch the coulter blade or any other attachments. Such contacts cause excess wear to all parts involved. At least1⁄2in. (13 mm) clearance is recommended.

1. When the blade is out of the soil, adjust the lock collar height to set the height of tine ﬁngers ﬂush with the bottom of coulter blade.

2. Side-to-side alignment can be done by rotating the shank mount around the vertical shaft and retightening the square head set screw.

3. The factory setting for Terra-Tine™ height is a distance of 5.4 in. (13.7 cm) from frame bottom to top of Terra-Tine™ mount.

Height may be adjusted at the mount set screw, or at the frame clamp. Changing arm angle also

changes tine height.

4. The factory setting for arm angle is minimum

(pivot mount hole closest to Terra-Tine™ mount).

Terra-Tine™ Down Force

Refer to Figure 59

A series of three holes in the spring adjuster and pivot mount plate provide ﬁve combinations for different

levels of spring tension. The following table shows the down-force levels available.

Note: All adjustments must be made with the applicator in

the fully raised position.

Vantage I Coulter Adjustments

Applies to model NP4000 or NP4000A/B with optional liquid capability.

Fertilizer release height is normally at or just above the ground, and is controlled by three adjustments:

Refer to Figure 60

1. Tool bar height: This affects coulter depth. The procedure for setting tool bar height varies with hitch type: See page 91

2. Fertilizer arm height (page 90): This affects arm height relative to the coulter. This adjustment is primarily to compensate for blade wear.

3. Coulter height (page 90): This affects coulter height relative to the tool bar, and is normally not adjusted.

Factory settings:

25 in. (63.5 cm) above ground at 4 in. coulter depth

7.5 in. (19.1 cm) coulter shank distance 1 in. (2.5 cm) release height

Vantage I Coulter Force

Coulter springs are set to 400 pounds (181 kg). In normal operation at target running depth, the spring is at full extension. It compresses brieﬂy as obstructions are encountered.

• In heavy no-till conditions, you may observe the

springs in compression most of the time. This means that the blades are not reaching the desired coulter depth. If applicator weight is available, you can increase the spring down-force to compensate.

• In light but rocky conditions, the factory spring setting

may be higher than needed. You can extend blade life by reducing the force at which the blades ride up over obstructions.

• Applicator weight, in almost all applicator

conﬁgurations, is generally sufﬁcient to load the coulters to the full 400 pound factory setting.

Setting all springs above 400 pounds might require the optional weight kit with some lighter triple-coulter conﬁgurations.

Figure 60

Vantage I 20in Coulter

To adjust the coulter spring:

Refer to Figure 60

1. Raise the applicator and install transport locks. See “Raising/Lowering Applicator” on page 51.

2. Determine the new spring length desired.

Spring Length Force at Blade

10.25in (26.0 cm) 300 lbs. (136 kg)

10.0in (25.4 cm) 400 lbs. (181 kg)

9.75in (24.8 cm) 525 lbs. (238 kg)

3. Measure the current length of the spring(s) to be changed. If already as short as 93⁄4in. (24.8 cm), or as long as 101⁄4in. (26 cm), do not further adjust them.

4. Loosen the jam nut .

5. Rotate the adjuster nut until the spring is at the new length. Tighten the jam nut.

Note: If all springs are continuously in compression, the

coulters can lift the wing frames off the ground (at the gauge wheels), resulting in uneven coulter depth and/or uneven seed depth. If the applicator is already operating at maximum down-pressure, reduce coulter depth.

Vantage I Coulter Height and Castering

Coulter height is the main control for application height. Coulters may need to be lowered for rows in tracks. Coulters applicator-wide need adjustment as blades wear.

If desired coulter depth cannot be achieved due to challenging soil conditions, consider installing the optional weight kit (page 153 and page 187).

Coulters may also be set for rigid row alignment, or limited castering.

Refer to Figure 61 and Figure 62

1. The factory setting for coulter height is a distance of 7.5 in (19.1 cm) from frame bottom to top of coulter mount casting.

At a tool bar height of 25 in (63.5 cm) above ground, this is a blade depth of 4 in (10.2 cm).

2. For ﬁelds where frequent sharp turns are unavoidable, you can reduce coulter plowing by allowing the coulters to caster at the pivot casting. Loosen the jam nuts at . Loosen the set screws just enough to allow the casting to swivel. Re-tighten the jam nuts. Do not remove the center stop screw.

3. As blades wear, keep the release height constant by raising the applicator weldment on the coulter arm. Loosen the bolts . Slide the weldment up. Tighten the bolts.

If the application height is still too low after this adjustment, the coulter blades may be worn and in need of replacement.

Refer to the Vantage I manual (204-376M) for further coulter adjustments.

Vantage I Blade Wear

Blade wear is normal and the rate of wear varies with ﬁeld conditions and operating depth. Consider replacing the blade when the initial diameter has been reduced by 1 to 2 inches.

Note: Although a nominal 20 inches in diameter, blades

are lightly larger and vary slightly with blade style.

Tool Bar Height Adjustment

Center section tool bar height is set by the tractor hitch. Lift-assist spacers (page 43) must be selected and in place to assure front-to-back level.

Wing end tool bar height is set by independent gauge wheels on each wing end. Wings are maintained at level in the ﬁeld with the weight-transfer system (page 92).

1. Move to smooth level ground with soil as similar as possible to ﬁeld conditions. Set tractor brakes.

2. Determine the desired coulter depth.

3. Unfold the applicator (page 56).

4. Raise the applicator to bring the wing coulters off the ground, and the wings slightly above level.

Refer to Figure 63

5. At each gauge wheel, use the crank to remove tension at the pin . Remove the pin.

6. Use the crank to extend the wheels far enough to keep the wing coulters off the ground.

7. Unfold the wings until the gauge wheels are on the ground. Set fold/lift circuit to Float.

8. Use the 2-point hitch to lower the applicator until the center section coulters are just at ground level.

9. Check frame front-to-back level and adjust spacers (page 43) as necessary.

10. Adjust the gauge wheel heights to bring the wing coulters to the same height as the center section (just above the ground).

11. Measure the length of exposed gauge wheel tube.

12. Crank the wheel up by the desired coulter depth (exposed tube length becomes length minus the

coulter depth). Capture this setting by re-inserting and securing the pin .

13. Crank the wheel up until the tube solidly contacts the pin. This transfers wheel loads to the pin, and not to the crank.

14. At the center section, measure the tool bar height above the ground. Operating height is this distance less the desired coulter depth.

15. Pull forward, lowering the 2-point hitch to operating height. Set a stop on the 2-point circuit to capture this height.

16. Adjust weight-transfer (page 92) to hold wings level at this coulter height for these ﬁeld conditions.

Figure 63

Gauge Wheel Adjustment

Equipment Damage Risk:

Use the pin . Crank the tube up against the pin. Wheel loads

transmitted to the crank can damage the crank.

Note: Turn crank clockwise to raise applicator (lower

wheel), and counterclockwise to lower applicator (raise wheel).

Note: At maximum height, the coulters are off the

ground. This conﬁguration is useful for unfolded parking, storage and service.

Make a record of the setting needed for coulter depth prior to setting for maximum.

Weight Transfer Adjustment

Weight Transfer Safety Information

Crushing and High Pressure Fluid Hazards:

This adjustment requires working near the unfolded and lowered applicator with the hydraulic system active. Assign two people to this task, one in the tractor, ready to shut down on hand signal from adjuster or any unplanned event.

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can penetrate the skin causing serious injury. Use a piece of paper or cardboard, NOT BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, seek immediate medical attention from a physician familiar with this type of injury.

Weight Transfer System

Refer to Figure 65 and Figure 66 on page 93

Inner wing fold cylinders can extend, during ﬁeld operation, to push the wings down using mainframe/center weight. Weight transfer is enabled by:

1. Set the FOLD / FIELD switch to FIELD.

2. Adjust the weight transfer valve .

The fold/lift circuit is set to continuous ﬂow (in unfold mode) to maintain the active weight transfer. This system is designed for use with tractors having closed center hydraulics. It is incompatible with open center systems.

Note: Do not set or adjust the weight transfer system if

the outer wings are not level with the inner wings at unfold. Do not use the weight transfer system to compensate for unfold stop adjustment issues. See “Unfold Stop Adjustment” on page 134.

Crushing Hazard:

Keep body parts clear of wings, row cleaners and coulters while adjusting. Keep all bystanders well away. You will be seriously injured or killed if you are caught between lowering row applicators and ground.

Falling Hazard - Tires Not a Step:

Do not use tires as steps or platforms. At some transfer settings, cylinders can raise lift-assist wheels sufﬁciently for them to spin. Gauge wheels can also be in light or no ground contact when the weight-transfer system is not active.

Adjust the weight transfer to achieve consistent coulter depth, while keeping the wings level with the center section. If insufﬁcient weight is transferred, outside

(wing) coulters may run higher than center section. If too much weight is transferred, center section may run high.

If adjusted when the tractor is cold, re-adjustment may

be required when the oil warms. Monitor the pressure gauges during early ﬁeld operations.

Refer to Figure 66

1. In ﬁeld conditions, unfold (page 56) applicator.

2. Set FOLD / FIELD to FIELD.

3. Lower applicator(page 51), and set or check application depth (page 43).

Caster Angle Adjustment

Note: Applies to NP4000 and NP4000A only. NP4000B

has ﬁxed angle lift-assist caster arms.

Your operations may require that the lift-assist tires be in-row or out-of-row. In-row spacing varies with basic applicator row spacing. Post-emergence (side-dress), for example, typically requires out-of-row placement. The forward caster parallel arm weldments may be pivoted and pinned for wheel spacing.

Changing Spacing

This is a two person operation. If the applicator frame is not precisely level, the caster arms may be difﬁcult to control with one hand.

1. Hitch the applicator to a suitable tractor (page 36).

2. Raise the applicator. Move to a level, and ﬁrm or hard surface.

3. While raised, remove any lift lock channel or spacers on the lift-assist cylinder.

4. Lower the applicator until the caster tires are just out of ground contact. Set the fold/lift circuit to Neutral and shut off the tractor.

5. Remove the hairpin cotter at a caster pin. Have one person control caster position. Remove the pin.

6. Reposition caster as desired. Insert pin. Secure with cotter. Repeat for other caster.

Loss of Control and Machine Damage Risks:

Never operate with one or both pins removed, or with pins installed but not in a caster weldment tube. Always install the caster pin from the top, in case cotter is lost. If the caster arms are free to pivot at both ends, they can strike other applicator components, and directional control is substantially reduced. This could contribute to machine upset, a road accident, serious injury or death.

Caster Adjustment

Refer to Figure 68 (depicting the pin in holes 2+a

Fertilizer Rates

Anhydrous Fertilizer Rate

Rate setting for anhydrous ammonia is controlled entirely by the console. For the Raven SCS 450 available from Great Plains, see page 44.

Conventional Liquid Fertilizer Rate

Rate setting is materially different for each pump type:

• Ground Drive: rate is positively set by the drive system and piston pump dial.

• Hydraulic Drive: rate is set on the console. The console operates a ﬂow control valve. The valve adjusts the rate up to the peak value available at the current setting for hydraulic pump rpm.

Make adjustments to oriﬁce plates to provide backpressure, keeping the boom within a speciﬁc safe pressure range that assures consistent delivery.

Rate Setting Steps:

1. Determine the rate (below).

2. Install suitable oriﬁce plates (page 100).

3. Check strainer screen size (page 102).

4. Ground Drive: Set the ground drive Range

(page 103), and ground drive dial (page 104).

Hydraulic Drive: Set the pump pressure (page 105); set the desired rate on the console (see 016-0159-831 Raven SCS 450 Installation, Operation and Service manual).

5. Check the manifold pressure and relief valve during

operation (page 103).

Determining Application Rate

Great Plains recommends checking with your local agronomist as soil conditions vary. Soil conditions in your area may need less or more fertilizer than represented in the chart.

If your target rate is weight per area, you need to know the material density to convert it to liquid volume measure:

Volume_per_Area Weight_per_Area Density÷=

Ground Drive:

The tables, and web calculator provided expect rates to be expressed as

[U.S.customary] gallons per [U.S.Survey] acre or liters per hectare.

The slide chart provided is gal/ac only.

If you want to use the slide chart, and have only a metric rate value, convert it to U.S.customary units:
