Important Safety Information

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.h

Be Familiar with Safety Decals

▲ Read and understand “Safety Decals” on page 7,

thoroughly.

▲ Read all instructions noted on the decals.

▲ Keep decals clean. Replace damaged, faded and illegible

decals.

2012-03-28 Table of Contents Index 407-776M

Page 6

2 NP4000 Table of Contents Index Great Plains Manufacturing, Inc.

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.

▲ Goggles with side shields or a full face respirator is

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 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.

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.

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

Minimize Radiation Exposure

The 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.

Use Safety Lights and Devices

Slow-moving tractors and towed implements 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 implement.

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 implement 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.

Page 8

4 NP4000 Table of Contents Index Great Plains Manufacturing, Inc.

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 ft. (4 m). Overhead lines at farm structures are a particular hazard. An incorrectly folded implement is at risk from lines lower than 22 ft. (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 30m (100 feet) 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 implement 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.

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

with the implement on public roads.

▲ 3-point implements reduce weight on steering tires. Verify

that tractor is correctly ballasted. Watch for signs of poor steering traction.

▲ Carry reﬂectors or ﬂags to mark fertilizer applicator in

case of breakdown on the road.

▲ Verify that the implement is properly folded (page 39).

▲ Keep clear of overhead power lines and other obstructions

when transporting. Refer to transport dimensions under “Speciﬁcations and Capacities” on page 101.

▲ Do not exceed 20 mph. 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.

Handle Chemicals Properly

Agricultural chemicals can be dangerous. Improper use can seriously injure persons, animals, plants, soil and property.

▲ Read and follow chemical supplier instructions.

▲ Wear protective clothing.

▲ Handle all chemicals with care.

▲ Agricultural chemicals can be dangerous. Improper use can

seriously injure persons, animals, plants, soil and property.

▲ Inhaling smoke from any type of chemical ﬁre is a serious

health hazard.

▲ Store or dispose of unused chemicals as speciﬁed by the

chemical manufacturer.

▲ If chemical is swallowed, carefully follow the chemical

manufacturer’s recommendations and consult with a doctor.

▲ If persons are exposed to a chemical in a way that could

affect their health, consult a doctor immediately with the chemical label or container in hand. Any delay could cause serious illness or death.

▲ Dispose of empty chemical containers properly. By law

rinsing of the used chemical container must be repeated three times. Puncture the container to prevent future use. An alternative is to jet-rinse or pressure rinse the container.

▲ Wash hands and face before eating after working with

chemicals. Shower as soon as application is completed for the day.

▲ Apply only with acceptable wind conditions. Wind speed

must be below 5 mph. Make sure wind drift of chemicals will not affect any surrounding land, people or animals.

▲ Never wash out a hopper within 100 feet of any freshwater

source or in a car wash.

Shutdown and Storage

▲ Park on level ground.

▲ Unhitch and store the fertilizer applicator in an area where

children normally do not play.

Tire Safety

Tire changing can be dangerous and should be performed by trained personnel using correct tools and equipment.

▲ When inﬂating tires, use a clip-on chuck and extension hose

long enough for you to stand to one side–not in front of or over tire assembly. Use a safety cage if available.

▲ When removing and installing wheels, use wheel-handling

equipment adequate for weight involved.

Practice Safe Maintenance

▲ Understand procedure before doing work. Use proper

tools and equipment. Refer to this manual.

▲ Work in a clean, dry area.

▲ Lower the fertilizer applicator, put tractor in park, turn off

engine, and remove key before performing maintenance. If work must be performed with implement raised, use blocks or jackstands rated for the fertilizer applicator weight.

▲ Make sure all moving parts have stopped and all system

pressure is relieved.

▲ Allow applicator to cool completely.

▲ Disconnect battery ground cable (-) before servicing or

adjusting electrical systems.

▲ Welding: Disconnect battery ground. Avoid fumes from

heated paint.

▲ Inspect all parts. Make sure parts are in good condition

and installed properly.

▲ Remove buildup of grease, oil or debris.

▲ Remove all tools and unused parts from fertilizer

applicator before operation.

Safety At All Times

Thoroughly read and understand the instructions in this manual before operation. Read all instructions noted on the safety decals.

▲ Be familiar with all applicator functions.

▲ Operate machinery from the driver’s seat only.

▲ Do not leave applicator unattended with tractor engine

running.

▲ Do not stand between the moving tractor and applicator

during hitching.

▲ Keep hands, feet and clothing away from power-driven

parts.

▲ Wear snug-ﬁtting clothing to avoid entanglement with

moving parts.

▲ Make sure all persons are clear of working area.

Application Overview

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

Implement System Components

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

If the implement 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.

Refer to Figure 3 on page 17 and Figure 4 on page 18

11. 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 98) on the implement. 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.

12. 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 10in vented screw-on lid. Tanks may be ﬁlled at the top or via the quick ﬁll .

13. 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 tank discharge closed (shut off at valve)

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

Note: Callouts 11 to 50, correspond to the items

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

14. Tank Drain Elbow

Tank Option: This open elbow ﬁtting is used for material recovery and tank wash-out (page 79).

15. 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

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

16. 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 2in MCL.

17. 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.

18. 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 69 for alternative screen sizes and page 80 for maintenance.

19. 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.

20. 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 64 for ground drive rate setting.

Great Plains Manufacturing, Inc. Table of Contents Index Application Overview 15

21. 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.

22. 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 .

23. Gauge Protector

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

gauge from direct contact with corrosive fertilizer.

24. Pressure Gauge

Ground Drive Option: This 0-to-100 psi gauge reports the pressure in the manifold, which is typically 15-40 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.

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

25. Relief Valve

Ground Drive Option: Adjust this valve to activate at 65 psi (page 71). 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.

26. Dump Line

Ground Drive Option: If the relief valve operates,

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

plate conﬁguration.

27. 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.

28. Air Bleed Line

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

29. 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 SCS450 console.

30. 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

valve . Only one ﬂow meter can be monitored by a single Raven SCS450 console.

31. 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 BOOM switches on the Raven SCS 450a or other compatible console.

32. 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

monitored by a single Raven SCS450 console.

33. Boom

Boom Option: There is one boom assembly per implement 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.

34. End Cap

Boom Option: In the factory conﬁguration, the wing booms each have a cap. These caps are removed for clean-out (see page 79).

a. Although the Raven SCS450 has six section valves, the harness provided has only four Valve leads. Controlling more than three

valves with a single SCS450 would require the purchase of an alternate harness from Raven.

16 NP4000 Table of Contents Index Great Plains Manufacturing, Inc.

35. 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 79) 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 implement models). Active rows have nozzle bodies . Inactive stations have shutoff

caps .

36. Shutoff Cap

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

37. Gasket

Boom Option: This ﬂat O-ring seals the nozzle

39 36 35

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 gasket.

38. 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 70 for plate selection and installation.

39. Nozzle Body

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

40. Drop Tubing

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

41. Applicator 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 54).

42. Applicator 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 NP4000 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 conﬁgure the tanking system. Before using the fertilizer applicator for the ﬁrst time, and periodically thereafter, certain adjustments and calibrations may be required.

Initial Setup

See manual 407-776Q for pre-delivery items (normally completed by dealer), and ﬁrst-time/infrequent setup tasks, including:

• Adjust optional hydraulic pump needle valve (page 110).

• Install optional hydraulic drive console in tractor (page 111).

• Install other 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 82).

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

Pre-Application Setup

Complete this checklist before routine setup:

❑ Read and understand “Important Safety

Information” on page 1.

❑ 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 87.

❑ Check that all safety decals and reﬂectors are

correctly located and legible. Replace if damaged. See “Safety Decals” on page 7.

Hitching Tractor to Applicator

This manual presume the following (recommended) operations sequence:

1. Hitch tractor to applicator for transport: below

2. Transport applicator separately from a trailing nurse tank: page 40

3. Hitch a trailing nurse tank to applicator at ﬁeld: page 44

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.

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 is engineered to be used with Category II or Category III tractors.

Refer to Figure 6

This implement is factory set for Category III tractors. Category II requires an optional hitch pin kit (see page 93).

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:

11⁄8in. (28.6mm) I.D. × 17⁄16in. (36.5mm) 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 implement. Align lower links with the lower hitch clevis on implement. Adjust hitch bushings and spacers supplied with implement according to the category of your tractor. Lock pins in place.

5. Set hitch for Depth Control mode.

Loss of Control / Public Safety Hazards:

Do not transport on public roads with a nurse tank hitched to the applicator. See “Transport” on page 40.

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 8

On implements with more than one hydraulic circuit, hydraulic hoses are color coded to help you hookup hoses to your tractor outlets. Hoses that go to the same remote valve are marked with the same color.

Color Function

Red Lift

Gray Fold, Weight Transfer

Black Hydraulic Pump Drive (Option)

To distinguish hoses on the same hydraulic circuit, refer to hose label.

• The hose under an extended-cylinder symbol feeds a

cylinder base end, or the return side of a hydraulic motor.

• The hose under a retracted-cylinder symbol feeds a

cylinder rod end, or the pressure side of a hydraulic motor.

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

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.

Figure 8

31733

Hose Handles

Machine Function Risk:

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

a. 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 implements (other than Nutri-Pro®). Nutri-Pro® lift and/or fold and weight transfer may not function on this type of circuit.

407-776M Table of Contents Index 2012-03-28

Great Plains Manufacturing, Inc. Table of Contents Index Preparation and Setup 25

Hydraulic Pump Hookup

The hydraulic motor used is a 7 gpm (23 liter/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 sprayer functions.

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

Date Code

Refer to Figure 9

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 9

Ace Pump Connections

27141

“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 45 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 10

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 lift-assist circuit to slightly raise the implement. See “Raising/Lowering Applicator” on page 35.

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 Implement

During initial setup and periodically throughout the season, check that the implement 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 “Application Height Adjustment” on page 53.

To check level, lower the implement 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 implement until lift assist wheels are just off

the ground.

2. Raise implement until wheels touch ground just

ﬁrmly enough to resist spinning.

Refer to Figure 12 (which depicts a lock channel installed on the cylinder rod)

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

the rod between the cylinder end and clevis.

4. Raise and lower implement. 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.

Variable Rate Setup (Option)

This topic presumes that the Nutri-Pro®applicator has a Raven SCS 450 console, speed radar, ﬂow meter, pressure sensor, and section control valves. It also presumes that the console has been installed in the tractor cab per “Console Installation” on page 111.

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 (407-776M) 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 (or the Calibration Card) for the keystroke sequence for setting each of these values.

SCS 450: BOOM CAL

In the factory conﬁguration, the hydraulic drive Nutri-Pro® is connected to one boom (the front boom) and has one “boom section” (BOOM 1). Because the center and wings are operated as a single section, the BOOM CAL number is the swath of the entire implement. Use the values from the following table.

If using a modiﬁed row setup, determine the BOOM CAL per the Raven SCS 450 manual.

NP4000-1630SD 510 inches (1295 cm)

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 Raven ﬂow control bundles offered by Great

Plains do not include a speed sensor, nor the cable necessary to connect a Raven-compatible sensor or radar to the SCS 450. See page 97 for an available radar kit. See page 97 for harness cables available from Great Plains or Raven.

SCS 450: METER CAL

This is the pulse-vs.-rate calibration number for the ﬂow meter ( in system diagrams in this manual).

Obtain this number from the tag afﬁxed to the meter. Enter it into the SCS 450 and record on the Calibration Card.

SCS 450: VALVE CAL

This is the response time calibration number for the control valve ( in system diagrams in this manual).

Obtain this number from the tag afﬁxed to the valve. Enter it into the SCS 450 and record on the Calibration Card.

SCS 450: PRESSURE CAL

This DATA MENU sequence sets zero for the pressure transducer ( in system diagrams in this manual). Perform this operation only when lines are at zero pressure.

SCS 450: RATE 1 CAL

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 liquid fertilizer 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.

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.

1. Carefully review “Important Safety Information”

starting on page 1.

2. Lubricate fertilizer applicator as indicated under

“Lubrication and Scheduled Maintenance” on page 87.

3. Check all tires for proper inﬂation. See “Tire

Inﬂation Chart” on page 104.

4. Check all bolts, pins and fasteners. Torque as shown

in “Torque Values Chart” on page 105.

5. Check fertilizer applicator for worn or damaged

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

6. Check hydraulic hoses, ﬁttings and cylinders for

leaks. Repair or replace before going to the ﬁeld.

Implement Locks

The Nutri-Pro® NP4000 Applicator is equipped with several lock systems, which provide safety and/or operational functions. Manual and manual reset 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 14

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 implement (page 35) 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.

Outer Wing Lock Channels

Refer to Figure 15 and Figure 16

These 201⁄4inch (51.4 cm) manual lock channels are installed on the outer wing fold cylinders only for ﬁeld operations. They (and the inner wing locks) provide stops limiting fold during lift for ﬁeld turns. The locks are held in place by a bent pin . See “Unfolding and Folding” on page 37.

Fully unfold the implement (page 37) to install or remove these locks.

Note: If the outer wing has not fully unfolded due to

ground contact, pull forward to bring wings level.

When not installed, the outer wing locks may be stored at the mounting tab on the wing rest stops.

Note: Be sure to use the 201⁄4inch (51.4 cm) locks onthe

outer wing cylinders, and not the 11 inch (28 cm) lift-assist locks.

Wing Lock Pins

Refer to Figure 16

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 39.

Inner Wing Lock Channels

Inner Locks in Transport

Refer to Figure 17

These manual-reset lock channels ( and ) are permanently installed on the inner wing fold cylinder clevises. These locks (and the outer wing locks) provide stops limiting fold during lift for ﬁeld turns.

The rear cylinder lock , equipped with a spring plunger, also has a separate use during initial unfold, where it limits inner wing travel to eliminate risk of opener damage.

During pre-fold, transport and wings-folded storage, both lock channels are retained by a pin in a holder .

Inner Locks During Unfold

Refer to Figure 18

1. Withdraw the pin , releasing at least the

spring-plunger lock channel .

2. Swing the spring plunger toward implement

center, over the stroke control valve , and rest the spring-load bolt on the cylinder body.

3. Rest the standard lock channel on the front

cylinder face.

Inner Wing Locks in Field

See “Raising/Lowering Applicator” on page 35 for complete ﬁeld lift and lower instructions.

Refer to Figure 20

1. After initial unfold is complete (including outer wings, see page 37), set the fold circuit to Neutral.

Crushing Hazard:

Keep body parts clear of, and not beneath blades and knives when performing the next step. If the hydraulics are damaged or incorrectly conﬁgured, some vertical motion could occur when the spring-plunger is disengaged.

2. Rotate the spring-plunger assembly outward onto

Figure 20

the lock channel.

Note: Normally, nothing happens when the plunger is

disengaged. The actuator of the stroke control valve remains depressed until the next step.

3. As needed, set or reset the height of the wing gauge wheels.

4. Retract the fold circuit slightly. This resets (releases) the stroke control valve.

5. Extend the fold circuit until the gauge wheels are in ground contact.

6. Set the fold circuit to Float.

Inner Wing Locks Pre-Fold

See “Unfolding and Folding” on page 37 for complete unfolding and folding instructions.

Refer to Figure 21

1. As needed, extend the fold circuit to free the inner wing lock channels. If the inner wing is partially raised, the channels may be captured by the bolts at the cylinder faces.

2. Remove the pin at the holder.

3. Rotate the front lock channel fully outward.

4. Rotate the rear lock channel outward, while rotating the spring-plunger assembly inward, until the rear lock channel rests in the holder.

5. Secure both lock channels with the pin .

Outer Wing Fold Latches

Refer to Figure 22

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.

Raising/Lowering Applicator

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

The implement may be raised and lowered while folded.

Raise For Transport (Folded)

These steps presume an implement parked or stored folded, already raised, but on lift-assist locks and parking stands.

1. Verify that lock channels are installed on the lift-assist cylinders (page 31).

2. 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.

3. Raise the parking stands (page 25).

Gradual Crushing Hazard:

Do not rely on hydraulic pressure alone to keep the implement raised. Use parking stands (page 25) and transport/lift locks (page 31) when working around a raised implement. The tractor hitch may settle. The bypass oriﬁces in the implement lift-assist re-phasing system cause it to slowly lower.

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.

Raise Pre-Folding (Unfolded)

These steps presume an implement parked or stored unfolded, already raised, but on lift-assist locks at rear, on extended gauge wheels at wing tips, and on parking stands at hitch.

1. Verify that lock channels are installed on the lift-assist cylinders (page 31), on inner wing fold cylinders (page 31) and on outer wing fold cylinders (page 31).

2. Retract the fold circuit until all wing sections are stopped by lock channels (page 31). Set fold circuit to Neutral.

3. Raise the tractor 3-point hitch enough to lift gauge wheels, coulters, and the parking stand bases off the ground. Set the hitch circuit to Neutral. Shut off the tractor.

4. Raise the parking stands (page 25).

5. Start the tractor. Extend the fold circuit until the wings are level, or until all wing lock channels are free. Set fold circuit to Neutral. Shut off tractor.

6. Set inner wing lock channels for pre-fold (page 33). Remove and store outer wing lock channels (page 31).

Field Lift

Figure 23

32367

Partial Fold to Lock Channels

These steps presume an unfolded implement in ﬁeld conﬁguration (lift-assist locks out, spacers in, wing lock channels in, coulters in ground).

1. Set the fold circuit to Retract. Wing sections fold against the lock channels (see Figure 23 above).

2. Set the lift-assist circuit to Extend.

3. Raise the tractor 3-point hitch.

4. When partial fold and lifts are completed, set all three circuits to Neutral for extended turns or ﬁeld moves.

With some experience this lift can be done with near simultaneous circuit operation, and done while moving.

2012-03-28 Table of Contents Index 407-776M

Page 40

36 NP4000 Table of Contents Index Great Plains Manufacturing, Inc.

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 31).

2. Retract the lift-assist circuit to lower the lift-assist cylinders onto their locks.

Tip-Over and Crushing Hazard:

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

3. Raise the tractor three-point hitch until the implement 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.

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

5. Start the tractor. Lower the tractor hitch until the implement is supported by the parking stands.

Equipment Damage Risk:

Although it is possible to fully lower the implement while folded (with parking stands in place or while hitched), this is not recommended. This can place the full weight of the machine on the center coulters, exceeding their spring capability.

Lower While Unfolded

These steps presume that the intention is to park, store or service the implement, and that lift-assist lock and parking stands are to be used. For ﬁeld lower and ﬁeld adjustments, see topic “Field Lower” following.

1. Verify that all lock channels are in place on wing fold cylinders.

2. To keep all coulters off the ground when unfolded and lowered, crank the gauge wheels to full extension (page 55).

3. Retract the fold circuit until inner and outer wing fold is stopped by lock channels.

4. Set the fold circuit to Neutral.

5. Extend the lift-assist circuit to fully raise the implement at rear. Set circuit to Neutral.

6. Raise the tractor three-point hitch until the implement 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.

7. Install the lock channels at the lift-assist cylinders (page 31).

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

9. Start the tractor. Retract the lift-assist circuit until the cylinders rest on the lock channels.

10. Lower the hitch until the implement rests on the parking stands at front.

11. Extend the fold circuit until the gauge wheels touch the ground, then set the circuit to Float.

Field Lower

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

The key objectives for an optimal lowering are:

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

• avoid applicator plugging by avoiding any reverse motion of the applicator tips at the ground.

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

1. Check that wings are partially folded against locks,

or at least level. If they are drooping, retract the fold circuit to correct.

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

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

3. Retract the lift-assist circuit until the cylinders rest on

the spacers. Set the lift-assist circuit to Float.

Note: You may also lower the hitch and lift-assist

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

4. Pull forward.

5. Extend the fold circuit to level the wings. Set the

circuit to continuous for weight transfer.

Unfolding (Parking, Storage, Service)

To unfold, off ﬁeld, for parking, storage or servicing, unfold with the center section fully raised.

1. Hitch to a suitable tractor (page 22).

2. Extend the lift-assist circuit to fully raise the implement rear.

3. Raise the tractor 3-point hitch.

4. If lift-assist lock channels are not installed, set circuits to Neutral. Shut off the tractor. Remove spacers (page 26). Install lock channels (page 31). Re-start the tractor.

5. Un-pin all four inner wing lock channels (page 32). Swing the spring-plunger assemblies onto their respective fold cylinder bodies (page 32).

6. Extend the fold circuit to unfold the wings.

7. Set all circuits to Neutral.

8. Install the outer wing lock channels (page 31)

9. Swing the spring-plunger assemblies outward onto their lock channels (page 32).

10. Retract the lift circuit slightly to reset the stroke control valve. Extend the circuit to set the wings level.

11. Shut off the tractor.

12. Unless using blocks or stands under wings, fully extend wing gauge wheels (page 55).

Figure 25

Normal Unfold Sequence

Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 39

Folding

These instructions presume that the implement is unfolded and lowered.

1. Verify that the wing lock pins (page 31) are not in the wing rest cradles. Typically they are in storage tubes.

2. Set the fold/down-pressure circuit to Neutral.

3. Raise the implement (page 35). Set the lift and hitch circuits to Neutral.

4. As needed, use the fold circuit, bring the wings to near or slightly below level. Set fold circuit to Neutral. Shut off tractor.

5. Remove spacers (page 26). Install lift-assist cylinder locks (page 31).

6. Remove and store outer wing lock channels (page 31).

7. Rotate inner wing lock channels into holders and pin (page 33).

8. Start tractor. Retract fold circuit.

9. Watch outer wing sections. In a normal fold (Figure 26), the outer wings fold ﬁrst.

If the outer wings do not fold ﬁrst (as in Figure 27), STOP. Perform step 4, 6 and step 8 above.

Electrocution and Overhead Collision Hazards:

Do not fold with outer wings locks installed. Remove outer wings locks before folding. With locks installed, the folded implement may 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.

10. When both wings are seated in the wing rest cradles, set the fold circuit to Float.

11. Retract lift circuit to lower lift-assist cylinders onto lock channels. Set lift circuit to Float. Shut off tractor.

12. Install wing pins (page 31).

For parking/storage/service, lower the implement onto parking stands.

Transport

Loss of Control Hazards:

Never transport a 2-point implement unless the tractor is properly ballasted to provide adequate weight on the steering wheels. A heavy 2-point implement 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 implement, almost all of it borne by the tractor 2-point hitch. This can substantially reduce tractor steering and does increase braking load. The implement 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 implement that weighs more than 150% of the tractor (transport tractor must weigh at least 67% of implement). 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 implement plus any loaded nurse tank. This tractor weight requirement is substantially higher than for transport.

Transport Steps

Know your implement weight. See page 40 for a list of approximate weight of various conﬁgurations.

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

1. Check that fertilizer applicator is securely hitched to a sufﬁcient tractor (page 22)

2. Verify correct operation of lights.

3. Raise fertilizer applicator (page 35).

4. Install lift cylinder locks (page 31).

5. Fold applicator if unfolded (page 37).

6. Plan the route. Avoid steep hills.

7. Always have lights on for highway operation.

8. Do not exceed 20 mph (32 kph). 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 Implement Setup

Prior to hitching nurse tank, make and check ﬁnal implement adjustments. This could include:

• Application depth, page 53.

• Application Rate, page 64.

• Row cleaner adjustments, page 63.

• Make a dry run to check implement functions, running

depth and sealing.

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

Loading Materials

Filling Tanks

The tanks may be loaded from the quick-ﬁll inlet, or from the lids (page 43).

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 implement to a tractor. Filling an unhitched implement 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” on page 79.

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

Tank Quick-Fill

Refer to Figure 28 and Figure 3 or Figure 4 on page 17 or 18

5. Position the implement 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.

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.

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

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.

Hitching Nurse Tank

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

Mechanical Cart Hitching

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

Refer to Figure 30

2. Bring the implement 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 implement 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 implement 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 implement rear hitch tongue, at this time, by using the tractor to move the implement backward several inches, until the latch on the hitch re-engages.

Making Nurse Tank Connections

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

2. Route tank supply hose to implement 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 implement inlet, and any cap on tank supply hose.

4. Inspect and clean connector ﬁttings.

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

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

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 .

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).

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.

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:

tank discharge valves open to selector valve

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.

Ground Drive Pump Start-Up

4. Check ground drive sprocket setup (page 72).

5. Set rate on pump adjuster dial.

Refer to Figure 3 on page 17 or Figure 4 on page 18

6. If relief valve has not been previously adjusted,

perform initial setting per page 71.

Prime the Ground Drive System.

7. Wearing gloves, manually rotate the ground drive wheel until material appears at the applicator tubes.

Begin ﬁeld operations.

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

Hydraulic Drive Start-Up

Prior to ﬁrst use, determine the hydraulic remote circuit ﬂow rate setting per the procedure on page 73.

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 73.

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 applicators. Prime second hydraulic pump as required.

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

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 79.

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).

Pauses and Turns

Ground Drive Pauses and Turns

When the implement 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 implement 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 is 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 factory conﬁguration uses only Valve 1. If the plumbing system has been modiﬁed after delivery, it may be necessary to also

engage BOOMS switches 2 or 3.

Monitor Operation (Option)

Refer to Figure 31

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.

Starting Application with Console

1. Enter the tractor cab.

Refer to Figure 31

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

3. Set the MASTER switch to ON.

4. Set the BOOMS 1 switch

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.

Ending 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 72).

• Ground Drive: Set the pump dial to 10 (page 72).

• Hydraulic Drive: Set the console (Option) for

maximum rate.

4. Apply this water to the ﬁnal ﬁeld to ﬂush the pump and boom.

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

6. Disconnect all cam-lock couplers from the tank to the implement.

For a trailing nurse tank cart:

7. Disconnect the safety chains.

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

Piston Pump Damage Risk:

Ground Drive: When conﬁguring the 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.

Application Height Adjustment

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

Refer to Figure 32

1. Tool bar height: This affects coulter depth. The procedure for setting tool bar height varies with hitch type: See page 55

2. Fertilizer arm height (page 54): This affects arm height relative to the coulter. This adjustment is primarily to compensate for blade wear.

3. Coulter height (page 54): 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

Coulter Force

In normal operation at target running depth, the spring is at full extension or only slightly compressed. It compresses brieﬂy as obstructions and denser soil are encountered.

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 drill 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.

• Implement 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 32

Vantage I 20in Coulter

To adjust the coulter spring:

Refer to Figure 32

1. Raise the drill and install transport locks. See “Raising/Lowering Applicator” on page 35.

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 drill is already operating at maximum down-pressure, reduce coulter depth.

Coulter Height and Castering

Coulter height is the main control for application height. Coulters may need to be lowered for rows in tracks. Coulters implement-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 100 and page 122).

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

Refer to Figure 33 and Figure 34

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.

Tool Bar Height Adjustment

Center section tool bar height is set by the tractor hitch. Lift-assist spacers (page 26) 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 56).

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 implement (page 37).

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

Refer to Figure 35

5. At the 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 lift/fold circuit to Float.

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

9. Check frame front-to-back level and adjust spacers (page 26) 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).

Figure 35

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 implement (lower

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

Note: At maximum height, the coulters are off the

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

32354

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

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

Note: Prior to folding, fold the jack handle down

alongside the jack body. This retains the jack handle and prevents it from hitting the fertilizer tanks when folded (if so equipped).

Weight Transfer Adjustment

Weight Transfer Safety Information

Crushing and High Pressure Fluid Hazards:

This adjustment requires working near the unfolded and lowered implement 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.

2012+ Weight Transfer System

Applicators made in 2012 and later have two valve bodies and one gauge for the weight transfer system. 2011 applicators, described on page 58, have a single body with two gauges.

Refer to Figure 37 and Figure 40 (depicting NP3000)

Wing fold cylinders can extend, during ﬁeld operation, to push the wings down using mainframe/center weight. Weight transfer is enabled by opening the weight-transfer shut-off valve , and controlled by two adjustment valves ( and ). See circuit diagram on page 107. The fold circuit is set to continuous ﬂow (in unfold mode) to maintain the active weight transfer.

The weight-transfer shut-off valve must be open for weight transfer. When closed, it bypasses the reducing valve for faster fold cylinder operation (and faster 2-point lift-assist).

The pressure reducing valve controls the ﬂow to the cylinders.

The bypass valve returns excess oil to the tractor.

2 3

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 implements and ground.

Falling Hazard - Tires Not a Step:

Do not use tires as steps or platforms. At some transfer settings, cylinders can lift wheels sufﬁciently for them to spin.

4. Open weight-transfer shut-off valve .

5. Release the bypass valve lock disc . Turn the bypass valve knob fully clockwise to shut-off all bypass oil ﬂow. Tighten lock disc.

6. Set tractor to half throttle. Adjust tractor ﬂow control valve so that wings fold/unfold at a reasonable speed. Keep tractor running for step 7 through step 10.

Note: On 2-point implements, fold and unfold are followed

by lift and lower operations.

7. Set tractor remote circuit for unfold. Lock lever for continuous operation.

8. At the pressure reducing valve , release the lock disc .

9. Adjust the knob for an initial value of 800 psi on the gauge . Tighten the lock disc.

10. At the bypass valve , release the lock disc . Adjust the bypass valve knob counter-clockwise until the pressure reading just begins to fall from the value set at step 9. Turn the knob clockwise1⁄4turn. Tighten the lock disc.

11. Observe implement operation, and re-adjust down-pressure as necessary after oil warm-up. Repeat step 7 through step 10. The bypass valve needs to be closed prior to any adjustment to increase weight transfer.

both gauges read approximately 1100 psi (76 bar). Pressure might rise and then fall off as knob is opened. If pressure exceeds 1400 psi (97 bar) during this step, the tractor ﬂow is too high; reduce tractor ﬂow. Set bypass valve lock disc at 1100 psi.

10. Adjust Inside Wing pressure reducing valve knob

to 650-900 psi (45-62 bar) pressure setting, never exceeding 1100 psi (76 bar). Adjust Outside Wing valve knob to 650-750 psi (45-52 bar) pressure

setting, never exceeding 1000 psi. Set lock discs (

and ).

11. In ﬁeld operation, Lock the tractor hydraulic lever for the fold circuit for continuous downward oil ﬂow. If wings are running too high, increase pressure setting to the appropriate valve ( and/or ) to level

Caster Angle Adjustment

Your operations may require that the lift-assist tires be in-row or out-of-row. In-row spacing varies with basic implement 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.

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 implement components, and directional control is substantially reduced. This could contribute to machine upset, a road accident, serious injury or death.

Changing Spacing

Details of pin placement vary. See page 61 for 2012+ models See page 62 for 2011 models.

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

1. Hitch the applicator to a suitable tractor (page 22).

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 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 the caster as desired for the new spacing. Insert the pin. Secure with cotter. Repeat for other caster.

Row Implement Adjustments

Terra-Tine™ Adjustments

Note: All adjustments must be made with the implement

in the fully raised position.

Refer to Figure 46

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 47

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.

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.

Adjustments to oriﬁce plates must also be made to provide back-pressure, keeping the boom within a speciﬁc safe pressure range that assures consistent delivery.

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:

Rate Setting Steps:

1. Determine the rate (below).

2. Install suitable oriﬁce plates (page 69).

3. Check strainer screen size (page 71).

4. Ground Drive: Set the ground drive Range (page 72), and ground drive dial (page 72).

Hydraulic Drive: Set the pump pressure (page 73); 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 71).

Ground Drive:

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

Select and Install Oriﬁce Plates

Agricultural Chemical Hazard:

Wear protective gloves when changing oriﬁce plates. Consult material manufacturer or supplier documents for proper handling and steps to take if skin contact occurs.

Refer to Figure 48

Oriﬁce plates at each drop line nozzle provide

back-pressure that balances ﬂow in the manifolds, assuring that each row obtains the same ﬂow rate. For a given rate, there may be more than one oriﬁce size that provides the recommended back-pressure.

Plates are provided with the system in three sizes. Additional sizes are available. In general, the oriﬁce needs to be small enough to create a minimum pressure in the manifold but large enough to prevent the manifold pressure from exceeding the maximum:

15 psi min., 15-40 optimal, 65 psi max.

Using an oriﬁce size too large can result in unequal ﬂow at rows. Using a size too small can cause excess back-pressure resulting in material dumping at the relief valve.

Determine Oriﬁce Size

The chart below shows rate ranges for each Great Plains oriﬁce size and row spacing. You may need to change to the next higher or lower oriﬁce for a different fertilizer solution density and/or a different ground speed.

To reduce oriﬁce plugging and pump wear, use the largest oriﬁce practical for your fertilizer application rate.

Figure 48

Fertilizer Drop Line Nozzle

Material Loss or Misapplication Risks:

Oriﬁce size must be appropriate for rate selected. Drop line oriﬁce plates do not affect rate on ground drive pumps, and are not used to control rate on hydraulic drive pumps. If the oriﬁce size is too small, over-pressure in system may result in material loss at the ground drive relief valve. A size too small for a hydraulic drive system may require excess pressure to achieve the target rate. An oriﬁce size too large may result in uneven application across all rows.

If changing rate, changing material, changing ﬁeld speed or shutting off rows, review oriﬁce sizing.

Install Oriﬁce Plates

Refer to Figure 49

Insert the plate inside the gasket supplied with the nozzle . Insert the gasketed plate with the legend side

facing out the nozzle outlet (typically up).

In general, the oriﬁce needs to be small enough to

create enough pressure in the manifold to operate the check valves in the boom clamps, but not so much

that the system dumps product at the boom relief valve.

The recommend operating pressure is: 15 to 40 psi

Using an oriﬁce size too large can result in unequal ﬂow at rows, intermittent ﬂow, and ﬂow stoppage at rows where pressure falls below the 8 psi required to open the clamp check valve. Using a size too small can cause excess back-pressure resulting in material dumping at the boom relief valve.

Use the same size at all active rows.

36 38

Excess Back-Pressure Risk:

If using a size of 0.048in or larger, remove the 828-046C nozzle from the outlet of the coulter applicator tine.

Row Shutoff

Refer to Figure 49

Unused drop lines may be shut off by replacing the nozzle with a Great Plains 832-042C cap . Nutri-Pro® boom systems typically have more nozzles than coulters, and include caps for unused rows.

When installing a cap:

• It is not necessary to remove the gasketed oriﬁce plate

• Use a tie wrap or other line to secure the loose nozzle

• Adjust pump and/or oriﬁce plates for new rate and row

Mis-Application or Material Loss Risk:

Do not apply materials after row shut-off or row turn-on without ﬁrst reviewing setup. Merely changing the number of active rows does not change the application rate. If pump and/or oriﬁce size changes are not also made, pressures could be too low or too high.

Strainer Adjustment

Refer to Figure 50

A Banjo brand strainer is supplied with the ground drive fertilizer pump. It is plumbed before the CDS-John Blue pump. The standard 80 mesh screen should be suitable for most applications. Other screen sizes are available from Banjo Corporation.

If changing screen sizes, keep in mind the following.

• A smaller mesh (100) will keep very small manifold oriﬁce plates from plugging so often. However, the screen will have to be cleaned more often.

• A larger mesh (50) or (30) will pass more material but should only be considered when using large manifold oriﬁce plates.

• Mesh sizes below 30 are not recommended for use with CDS-John Blue pumps.

• A plugged or partially plugged screen will starve the pump resulting in a reduced application rate.

• Mesh sizes: (Smallest) 100, 80, 50, 30 (Largest)

Ground Drive: Setting Relief Valve

A relief valve is plumbed after the ground drive pump outlet to protect the manifold and pump from excessive pressure. Any product that activates the relief valve discharges from the dump line .

To set relief valve:

Refer to Figure 51

1. Unlock plastic jam nut from relief valve knob .

2. Unscrew knob counter-clockwise until it loses

contact with internal spring.

3. Screw knob clockwise two turns. Start at this setting.

4. While operating in the ﬁeld, observe manifold

gauge , and watch for relief valve discharge .

5. If valve is dumping product and gauge reads under

65 psi, stop tractor and turn knob clockwise (looking down)1⁄4 turn. Continue operating at normal ﬁeld speed. Repeat this step as needed until no product is discharged from relief valve.

6. If pressure gauge reads above 65 psi, change to a

larger oriﬁce. Go to step 2. Repeat steps.

Ground Drive: Set Pump Drive Range

Refer to Figure 52

Two Driving sprockets are provided for the pump: Low Range: 15T High Range: 47T

The choice of Driving sprocket depends on the application rate desired. The pump adjuster dial (see Figure 53) must be in the range 2-10 for consistent pump rate.

Use the rate chart on page 68 to determine which Range to use for the rate desired.

For implements with optional variable rate capability, choose the sprocket which, at dial setting 10, provides a rate higher than the maximum you intend to use. If Low range sufﬁces, use it for reduced pump wear.

To change Driving sprocket:

1. Loosen the bolt securing the rear idler . Slide the idler forward. Lift the chain off the lower Driving sprocket.

2. Remove pins at the storage and Driving shafts.

3. Exchange sprockets. Re-pin.

4. Re-engage idler for slack of3⁄8in (9mm) in the longest chain span .

1. Loosen the nut at the setting pointer.

2. Use the setting wrench to rotate the dial until the desired pump setting is under the pointer .

Note: Settings below 2 are not recommended.

If presently using High range, switch to Low range and use the dial setting for your rate in Low range.

3. Tighten the nut.

Material Loss/Equipment Damage Risks:

Operate only with material loaded, or disconnect chain or remove sprocket if not intending to apply material. Ground drive wheel and chain system operate whenever the implement is lowered and in motion. The pump must not be run dry.

Maintenance and Lubrication

Proper servicing and maintenance is the key to long implement life. With careful and systematic inspection, you can avoid costly maintenance, downtime and repair.

Always turn off and remove the tractor key before making any adjustments or performing any maintenance.

Crushing Hazard:

Always have transport locks in place and/or use stands when working on implement. You may be severely injured or killed by being crushed under a falling implement.

High Pressure Fluid Hazard:

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

1. After using your applicator for several hours, check all bolts to be sure they are tight.

2. Ground Drive: Remove excess slack from chains. Clean and use chain lube on all roller chains as needed.

3. Maintain proper air pressure in tires.

4. Keep pump full of liquid at all times.

5. Clean applicator on a regular basis. Regular and thorough cleaning will lengthen equipment life and reduce maintenance and repair.

6. Lubricate areas listed under “Lubrication and Scheduled Maintenance” on page 87.

7. Replace any worn, damaged, or illegible safety labels by obtaining new labels from your Great Plains dealer.

407-776M Table of Contents Index 2012-03-28

Material Clean-Out

With proper attention to maintenance, end of day clean-out, end of season clean-out and winterization, you can substantially increase the life and reliability of your fertilizer system. Protect the pump, clean the tanks, strainers, lines and nozzles, and you can avoid costly and time-consuming repairs at the next season.

Fertilizers are usually highly corrosive to metals other than stainless steel. Suspension fertilizers can clog system components in storage.

1. Flush entire system with clean water.

2. Remove end caps from booms and ﬂush booms out with water. Drain and replace end caps.

3. Remove strainer and drain it out. Drain all lines and tanks completely to prevent freezing damage.

4. Flush pump per pump supplier manual. Fill pump with RV antifreeze and cap off.

5. Wash all spilled fertilizer off the applicator.

Possible Chemical Hazard:

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. Avoid contact with skin or eyes. Seek medical assistance immediately if accident occurs. Know what to do in case of an accident.

Equipment Damage Risk:

Do not leave fertilizer or fertilizer residue in pump. Do not allow air to enter pump. Even for short periods of storage, the entrance of air into the pump causes RAPID and SEVERE CORROSION.

Tank Clean-Out

Refer to Figure 55 -which depicts the dischargevalvesopen to the selector valve (not shown)

For bulk recovery of unused material, or for rinsing out tanks, dump line elbows are provided at the tank discharge valves .

For connection of collection hoses, the elbows require a hose with 11⁄2inch inside diameter.

Possible Chemical Hazard:

Operate the valves from above. Wear chemical gloves. Inspect the valves from below only when ﬂow is shut off. Wear eye protection when working under the tanks.

The valve operating handles have the word “FLOW” and a raised arrow that point in the open direction of ﬂow. This provides tactile indication of handle orientation.

1. Connect any drain or collection hoses to the elbows .

2. Check that the selector valve is closed.

3. Rotate one or both tank discharge valve operating handles to the elbows.

4. As desired, rinse out tanks from open lids.

Note: Parts of the tank plumbing system (to the selector

valve) are below the elbows. These lines must be disconnected to completely drain them.

Liquid Fertilizer Strainer Maintenance

Refer to Figure 57

The fertilizer system uses an in-line strainer to keep damaging particulates out of the pump. The strainer becomes clogged over time, reducing pump rate. Plan to clean the strainer several times per season. Don’t wait for application rates to fall below target. Higher quality liquid fertilizers may require less frequent cleaning.

Disassemble and clean the strainer prior to storage to prevent caking.

In Season Filter Cleaning

1. Shut off the ball valve at the ﬁlter, to minimize product spill.

2. Unscrew and remove the bottom canister of the ﬁlter.

3. Wash the ﬁlter cartridge with water, or replace with new cartridge if necessary.

4. Reinstall the cartridge, canister, and turn on the ball valve.

End of Season Filter Cleaning

1. Load 10 to 15 gallons (40 to 60 liters) of clean water in each supply tank.

2. Pump most of it through the system. If doing this by hand-turning the ground drive wheel, ﬁrst install the largest drop-line oriﬁce size, and set the pump adjuster to maximum, to increase ﬂow.

3. With valves open, remove the canister. Clean strainer and canister.

4. Drain lines. Remove boom end-caps to drain wings.

5. Re-install strainer and canister.

6. Add 2 pints (1 liter) of RV antifreeze to the tank. Pump until tank is just empty (which leaves some ﬂuid in strainer).

7. Open supply line at pump inlet. Introduce RV antifreeze, and operate pump until pump is ﬁlled.

Pump Maintenance and Repair

Ace Hydraulic Pump

The Ace pump is designed for long life and service. Through the years, it may be necessary to replace the mechanical seal or service components of the pump. A mechanical seal may weep slightly, but if it starts to drip, the pump will have to be disassembled. Before disassembly, be sure to wash it out with fresh water.

If the pump leaks, before removal from applicator, run the pump with adequate water in tank to diagnose the actual pump problem.

Refer to the Ace Pump Instruction manual (HYD-MAN) for disassembly instructions.

Coulter Disc Replacement

Replace 20 in. (52 cm) coulter blades when adjusting application depth and/or applicator level becomes difﬁcult. Signs that blade replacement is indicated are:

• Coulter blade diameter is close to, or below, 15 in. (38 cm).

• Height adjustment, when level, requires no lift-assist spacers (page 26).

• Fertilizer arm adjustment is at the upper limit (page 53).

See page 94 for replacement and alternate coulter blades.

Hydraulic Maintenance

As with any hydraulic system, contamination is the most common cause of performance problems and pre-mature wear. Make a special effort to properly clean

quick couplers prior to attaching the hoses to tractor, and never let them fall to the ground.

High Pressure Fluid Hazard:

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

Bleed only at JIC and NPT ﬁttings. Never try to bleed a QD (Quick Disconnect) ﬁtting. Avoid bleeding at ORB ﬁttings. The O-ring is likely to be torn if any pressure remains in the circuit.

Crushing Hazard:

When reconnecting ﬁttings at fold cylinder ports, verify that a

0.063 inch (1⁄16inch, 1.6 mm) oriﬁce plate (Great Plains part number 196-430D) is installed at each port. A missing plate could result in a dangerously fast unfold, which might result in equipment damage, injury or death.

System Contamination Risk:

Always use liquid pipe sealant when adding or replacing NPT (National Pipe Thread, tapered thread) pipe-thread ﬁttings. To avoid cracking hydraulic fittings from over tightening, and to keep tape fragments from clogging filters, do not use plastic sealant tape.

Over-Torque and Leak Risks:

JIC (Joint Industry Conference 37° Flare) ﬁttings do not require high torque. Excess torque causes leaks. JIC and ORB (O-Ring Boss) ﬁttings do not require sealant.

Bleeding Lift Hydraulics

Normally bleeding should not be required other than to raise fully and hold lever on for one minute or until all cylinders extend fully.

Bleeding Fold Hydraulics

Normally the fold hydraulics are bled at the factory before shipping, and bleeding should not be required.

1. Connect the fold circuit to a hydraulic source, such

as a tractor remote.

2. Set the source circuit to Float to relieve any pressure

in the lines.

3. Disconnect both base and rod ends of all fold

cylinders.

4. Support the cylinders with ports facing up, and with

cylinders oriented so that rods cannot strike implement parts when at full extension.

5. Orient cylinders with base ends higher than rod

ends. Set circuit to Neutral.

One cylinder at a time:

6. Crack (slightly loosen) a JIC connection at a fold

cylinder base end.

7. Extend the circuit slowly until ﬂuid appears at the

ﬁtting.

8. Set the circuit to Neutral. Tighten the ﬁtting.

9. Repeat step 6 through step 8 for the remaining

cylinders.

10. Retract the fold cylinders. Set circuit to Neutral.

11. Orient cylinders with rod ends higher than base

ends.

One cylinder at a time:

12. Crack (slightly loosen) a JIC connection at a fold

cylinder rod end.

13. Extend the circuit slowly until ﬂuid appears at the

14. Set the circuit to Neutral. Tighten the ﬁtting.

15. Repeat step 12 through step 14 for the remaining

cylinders.

16. Set circuit to Float.

17. Re-pin base and rod ends of cylinders to center

section and wing lugs.

18. Test fold function carefully.

Crushing and Equipment Damage Hazards:

Bleed after servicing fold cylinders or their hoses. Air in the system makes it hazardous to fold the implement. If it is necessary to service fold hydraulics while folded, the ﬁrst unfold is especially dangerous. Wing motion can be uneven or jerky in fold. Unfolding wings could fall suddenly. Anyone nearby could be seriously injured or killed. Equipment damage is likely.

High Pressure Fluid Hazard:

Wear safety goggles and gloves. The bleed procedure requires partially opening pressurized hydraulic lines. Escaping ﬂuid under pressure can penetrate the skin, causing serious injury. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

Wing Leveling

Before checking wing level, check that the center section is level left to right (“Rear Eyebolt Adjustment”). Rear eyebolts above the rear casters can affect left-right level if out of adjustment.

Wing level is controlled entirely by gauge wheel height. If wings are not running level, adjust gauge wheels.

Rear Eyebolt Adjustment

Side to side level at rear is controlled by eyebolts at the lift cylinder bases. On 2-point, rear height is set by spacers (page 26).

Check that both eyebolts are set to the same reveal .

Refer to Figure 59

The factory setting is a distance of:

4.5 in. (11.4 cm)

from the end of the eyebolt to the top face of the lug tube.

To adjust the eyebolt, loosen the hose guide nut , then the jam nut . Rotate the adjust nut to set bolt reveal.

Check that the hose loop is on top. Tighten jam nut , then hose guide nut .

Caster Brake Adjustment

Refer to Figure 60

The rear lift-assist wheels each have independent adjusters for the caster pivot brake. The piston acts as a pivot brake, and helps prevent caster oscillation during transport. The adjustments will vary depending on different ﬁeld-to-ﬁeld conditions as well as road transport conditions.

If the caster is oscillating during transport turns or in ﬁeld use, adjust the pressure plate bolt .

Pressure Plate Adjustment

Refer to Figure 60 and Figure 61

1. Loosen the jam nut .

2. Turn the bolt counterclockwise until the bolt is

turning freely.

3. Drive screw in (down) until it contacts spring plate .

4. Drive screw in another 1 inch (2.5 cm).

5. Tighten the jam nut.

Use more tension as needed to eliminate caster vibration during highway transport.

Replace UHMW piston if its length is less than

⁄4in. (3.2 cm). Also replace piston if missing,

damaged, tilted, or top of piston is visible.

Chain Maintenance (Option)

Initially check the ground drive pump chains after the ﬁrst 10 hours of applicator use. The slack of new chains tends to increase during the ﬁrst few hours of operation due to seating. Thereafter, check the chains every 100 hours.

Lubricate chains any time there is a chance of moisture, and when being stored at the end of the planting season.

Chain Slack

Refer to Figure 62, which, for clarity, greatly exaggerates slack, and omits the idlers.

1. Measure the span for allowable slack: Locate the longest span of each chain (usually the span which does not run through the idlers).

2. Determine the ideal slack: Long chains (over 36 in. / 91 cm):

⁄4in. per ft. (21 mm/m)

Vertical short chains:

⁄4in. per ft. (21 mm/m)

Horizontal short chains:

⁄2in. per ft. (42 mm/m)

3. Measure the current slack : Acting at a right angle to the chain span at the centre of the span, deﬂect the chain in both directions. The slack is the distance of the movement.

4. Adjust the idlers for ideal slack.

Whenever mounting a chain, make sure the clip at the removable link is oriented to minimize snags.

Refer to Figure 63 (arrow shows chain direction)

Install clip with open end facing away from direction of chain travel (shown by gray or striped arrows in chain routing diagrams).
