NP2540 Table of Contents Index Important Safety Information 2
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER, and the color Safety Red, indicate an
imminent hazard which, if not avoided, will result in death
or serious injury. This signal word is limited to the most
extreme situations, typically for machine components
that, for functional purposes, cannot be guarded.
WARNING, and the color Safety Orange, indicate a
potential hazard which, if not avoided, could result in
death or serious injury, and includes hazards that are
exposed when guards are removed. It may also be used
to alert against unsafe practices.
CAUTION, and the color Safety Yellow, indicate a
potential hazard which, if not avoided, may result in
minor or moderate injury. It may also be used to alert
against unsafe practices.
Prepare for Emergencies
Be prepared if a fire starts.
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone. Know the reporting
requirement for spills or releases of the chemicals you are
using. Have contact numbers available.
For anhydrous ammonia operations, have additional
contact information for:
• national response center
• regional (state) response center
• local response center
If a fire threatens an anhydrous ammonia tank, evacuate
the area. The tank may heat up faster than the relief valve
can vent the rising pressure, resulting in a catastrophic
gas release and possibly an explosion.
Be Familiar with Safety Decals
Read and understand “Safety Decals” on page 9,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

NP2540 Table of Contents Index Important Safety Information 3
Wear Protective Equipment (PPE)
Wear clothing and equipment appropriate for the job.
Avoid loose-fitting clothing.
Waterproof, wide-brimmed hat
Face shield, goggles or full face respirator.
Prolonged exposure to loud noise can cause hearing
impairment or loss. Wear suitable hearing protection such
as earmuffs or earplugs.
Avoid wearing entertainment headphones while operating
machinery. Operating equipment safely requires the full
attention of the operator.
See manual 407-551M for specific requirements and
recommendations for NH
Goggles with side shields or a full face respirator are
required if handling or applying dusts, wettable powders,
or granules or if being exposed to spray mist.
Cartridge-type respirator approved for pesticide vapors
unless conventional liquid fertilize label specifies another
type of respirator.
Waterproof, unlined gloves. Neoprene is recommended.
Cloth coveralls/outer clothing changed daily; waterproof
items if there is a chance of becoming wet with spray.
Waterproof apron
Waterproof boots or foot coverings
Do not wear contaminated clothing. Wash protective
clothing and equipment with soap and water after each
use. Personal clothing must be laundered separately from
household articles.
Clothing contaminated with certain pesticides must be
destroyed according to state and local regulations. Read
chemical label for specific instructions.
PPE.

Use Safety Chains
(For all nurse tanks)
Use chain with a strength rating equal to or greater than
the gross weight of towed machinery.
Attach nurse tank chain(s) to anchors provided on
applicator. Allow only enough slack in chain for turns.
Replace chain if any links or end fittings are broken,
stretched or damaged.
Do not use safety chain for towing.
Current regulations require two chains on anhydrous
ammonia nurse tank carts.

Page 8
NP2540 Table of Contents Index Important Safety Information 4
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury. This fertilizer applicator requires a
Power-Beyond port, which is always under pressure
when the tractor is running.
Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
If an accident occurs, seek immediate medical attention
from a physician familiar with this type of injury.
Minimize Radiation Exposure
The optional DICKEY-john® RVS II and RVS III Radars
are intentional radiators of RF energy. Although its
radiated energy level is far below the limits set by
EN 61010-1:1993 A2:1995-Chapter 12.4, it is advisable
not to look directly into the face of the unit.
The radar must radiate toward the ground and at least
20 cm (8 inches) away from a human during use to
comply with the RF human exposure limits as called out
in FCC 47 CFR Sec.2.1091. DO NOT RE-MOUNT OR
USE THE RADAR IN A MANNER INCONSISTENT
WITH ITS DEFINED USE.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
Never allow children to operate equipment.
Keep all bystanders away from machine during operation.
Use Safety Lights and Devices
Slow-moving tractors and towed applicators can create a
hazard when driven on public roads. They are difficult to
see, especially at night.
Use flashing warning lights and turn signals whenever
driving on public roads.
Use lights and devices provided with applicator.
Tires Not a Step
Do not use gauge wheel or lift-assist tires as steps. A tire
could spin underfoot, resulting in a fall onto the applicator
or ground, possibly causing serious injury.
The gauge wheel tires can be in poor ground contact at
any time, even with the fertilizer applicator lowered in the
field. They can appear to be in ground contact, and spin
easily, in multiple conditions.
The lift-assist tires can be in poor ground contact, or out
of ground contact, whenever the fertilizer applicator is
lowered.
2019-04-12 Table of Contents Index 417-459M
Page 9
NP2540 Table of Contents Index Important Safety Information 5
Remain Clear of Overhead Lines
If the fertilizer applicator contacts a power line, lethal
voltage may be present on all metal parts. At higher
voltage, the applicator does not need to be in line contact
for the hazard to exist. Maintain at least 10 foot (3 m)
clearance.
Electrocution can occur without direct contact between
the energized fertilizer applicator and a person near the
fertilizer applicator.
Watch for sagging, damaged or low electrical lines. The
folded fertilizer applicator could contact lines lower than
13 foot (4 m). Overhead lines at farm structures are a
particular hazard. An incorrectly folded applicator is at
risk from lines lower than 22 foot (7 m).
Watch for all electrical lines during folding and unfolding
operations. Use a spotter during folding and unfolding.
Know the location and height of all lines during transport
and in fields.
If an electrical hazard is observed while on the ground
near the applicator, hop at least 100 feet (30 m) away
with both feet together and summon professional help. At
higher voltage, lethal voltage gradients can also be
present at the soil surface.
Consult your tractor manual for advice on how to respond
to an electrical hazard event while in the cab.

NP2540 Table of Contents Index Important Safety Information 6
Transport Machinery Safely
Maximum transport speed for applicator is 20 mph (32
kph), 13 mph (22 kph) in turns. Some rough terrains
require a slower speed. Sudden braking can cause a
towed load to swerve and upset.
Do not transport an applicator that weighs over 20,000
pounds (9060 kg). Loading liquid fertilizer tanks or
transporting with a nurse tank hitch to the applicator can
easily exceed this limit.
Tow nurse tank separately. Do not tow a nurse tank in
train with the applicator on public roads.
Never park an anhydrous ammonia tank on public roads
or anywhere near sites with high occupancy or high-risk
populations, such as shopping areas, events, schools,
hospitals, retirement communities, etc.
Avoid transporting an anhydrous ammonia tank through
populated areas.
Do not tow a lift-assisted 2-point applicator or nurse tank
that, when fully loaded, weighs more than 1.5 times the
weight of towing vehicle.
Do not transport a 2-point applicator that exceeds the
capacity or ballasting of the tractor. There may not be
enough front wheel traction for safe steering.
Carry reflectors or flags to mark fertilizer applicator in
case of breakdown on the road.
Keep clear of overhead power lines and other
obstructions when transporting. Refer to transport
dimensions under “Specifications and Capacities” on
page 155.
Do not exceed 20 mph (32 km/h). Never travel at a speed
which does not allow adequate control of steering and
stopping. Reduce speed if towed load is not equipped with
brakes.
Reduce speed on rough roads.
Comply with national, regional and local laws.
Do not fold or unfold the fertilizer applicator while the
tractor is moving (other than field lift).

system has two of components through , and two
additional dual-tube knives or tines .
Refer to Figure 3 on page 24
A11.Acme cap
Suffocation, Blinding and Burning Hazards:
See “NH3: Safing Applicator Before Cart Hitch” on
page 59, for safe opening procedure.
This captive cap protects the inlet when no nurse
tank is connected. NH
might be sealed behind this
3
cap.
A12.Acme inlet
The nurse tank hose coupler connects here and
must have 1
3
/4-4 female Acmea swivel coupler. See
page 62 for nurse tank connection.
A13.Coupler Inlet Bleed Valve
Suffocation, Blinding and Burning Hazards:
See “About Bleed Valves:” on page 36.
A14.Breakaway Coupler
Upon Event: Probable Chemical Hazard:
See “NH3: Breakaway Event” on page 69.
This assembly is designed to separate and seal the
lines if between 300 to 400 pounds of pull force is
applied to the nurse tank hose. In normal operations,
this never happens.
Should the hitch fail, and both safety chains fail, or
an operator makes serious basic safety errors, the
breakaway separates to protect the hoses from
rupture. Spring-loaded checks inside the breakaway
seal both ends of the now-broken connection. If the
line was charged, 60 cc of liquid NH
breakaway.
Resetting a parted breakaway coupler is a complex
operation requiring tools. Consult the breakaway
manual for details. More significant matters are
safing the applicator and nurse tank, then correcting
the cause of the breakaway. See “NH3: Breakaway
Event” on page 69.
A15.Breakaway Hydrostatic Relief Valve
In normal operation, this valve never activates. It is
designed to open at 375 psi, well above the
250-265 psi operating pressure of the nurse tank’s
main pressure relief valve. Operator action is
periodic inspection, and to replace this hydrostatic
relief valve, a time-dated part, when it reaches the
end of its operating life (see page 123).
See “Hydrostatic Relief Valve Maintenance” on
page 121 for maintenance.

A16.Coupler Outlet Bleed Valve
Suffocation, Blinding and Burning Hazards:
See “About Bleed Valves:” on page 36.
This fitting is kept closed in normal operations. When
the breakaway is properly coupled, the inlet bleed
valve bleeds the entire assembly, and applicator
supply hose. On breakaway, this valve is used to
bleed the applicator side of the disconnection.
See “NH3: Breakaway Event” on page 69.
A17.Supply Hose
This connects the breakaway coupler to the
emergency shut-off valve. Operator action is to
replace this hose, a time-dated part, when it reaches
the end of its operating life (see page 123).
A18.Emergency Shut-off Valve
The handle of this is valve has a rope which is routed
to the tractor cab (see page 36). Closing this valve
stops NH
flow to the cooler, metering system and
3
rows. There can still be a substantial amount of NH
in the system, for some time, with this valve closed.
See the “Using Anhydrous Ammonia Safely”
manual (407-551M) for emergency operation.
If the handle has a warning decal (page 14), the ball
may have a cavity that can contain a hazardous
amount of NH
if closed with the line full.
3
A19.Strainer
This filter contains a 20 mesh screen and two
ceramic magnets to remove debris from the NH
flow.
A20.Strainer Magnets
These capture ferrous metal debris of any size. They
need to be cleaned every 4 to 5 tank loads. See
page 126.
A21.AccuFlow™ Super Cooler (Heat Exchanger)
For effective application, NH
needs to remain in the
3
liquid state until released underground. This is
accomplished by refrigeration. Some of the flow is
tapped , fed back to the cooler at , vaporized
and used to chill the fluid passing from to .
A22.Cooler Intake
Liquid NH
enters the cooler here.
3
A23.Cooler Hydrostatic Relief Valve
In normal operation, this valve never activates. NH
can get trapped in the system between the
emergency shut-off valve and the On/Off
valve , if both valves are closed while the system
is charged. As the liquid warms and pressure rises,
this valve protects the system with periodic releases.
This valve is set to activate at 350 psi, higher than
the nurse tank’s relief valve.
Operator action is periodic inspection, and to replace
this hydrostatic relief valve, a time-dated part, when
it reaches the end of its operating life (see
page 124). See “Hydrostatic Relief Valve
Maintenance” on page 121 for maintenance.
A24.Cooler Outlet
Chilled liquid NH
exits the cooler here.

A25.Flow Meter
This fitting converts fluid flow to pulses for the
SCS 450 controller. It has a range of 1-60 gpm. A tag

between the emergency shut-off valve and the
On/Off solenoid valve (the Control Valve
does not completely close).
Checking the pressure and temperature against
the chart in the “Using Anhydrous Ammonia
Safely” manual (407-551M), or in the Raven
AccuFlow™ manual, indicates whether the flowing
NH
is in a liquid state.

When valves are open but NH
is not flowing, this
3
gauge normally reads within 5 psi of the nurse tank
pressure gauge . If they are materially different at
zero flow, one of the gauges may be defective.
When NH
is flowing, the pressure reported by this
3
gauge is lower than the tank pressure.
A29.Cooler Bleed Valve
Suffocation, Blinding and Burning Hazards:
See “About Bleed Valves:” on page 36.
This valve is normally closed. It is used to bleed
trapped NH
from the cooler system when valves are
3
closed. It can also be used to accelerate clearing the
cooler system for maintenance.

A31.Master Shut-Off Valve
This is the normal control for starting and stopping
application flow in the field (for turns, etc.). This
component is an open/closed solenoid valve
controlled by the SCS 450. The “MASTER” switch on
the SCS 450 controls this valve. When power is off,
this valve remains at its most recent setting.
This valve has a visible indicator above the valve ball
casing, indicating whether open or closed.
Operation of this valve is essentially instantaneous.
Its valve ball is equipped with a downstream relief
orifice.
A32.Refrigerant Tap
A small amount of the NH
flow is taken at this point
3
to provide refrigeration at the cooler. There are no
operational items for this fitting.
A33.Refrigerant Line
This tubing passes tapped refrigerant NH
cooler. Operator action is to replace this tubing, a
time-dated part, when it reaches the end of its
operating life. See page 124.
A34.Cooler Refrigerant Inlet
Tapped refrigeration flow enters the cooler at this
fitting, and is vaporized to chill the liquid entering at

causes the total flow to be reduced by
1
all-sections-on rate, keeping the rate constant for the
section(s) still active.
Each section valve has a visible indicator above the
valve ball casing, indicating whether open or closed.
Operation of each section valve is essentially
instantaneous. However, there is considerable
residual NH
in the section flow divider and delivery

or
shroud containing the female Acme fitting. This
allows connection without needing to twist the hose.
Acme hose couplers are intended for hand tightening
only. Do not use tools to make the cart-applicator
connection. A liquid-tight seal is made by the gasket
in the male Acme fitting on the applicator breakaway
coupler.
A57.Outlet Hose Assembly
The hose may have zero, one or two operating
valves , one or more bleed valves, and a
hydrostatic relief valve. The outlet end may have an
Acme plug.
Hose valves are typically hand wheel valves, or lever
valves. Read any documents provided for the valves.
Have the terminal or dealer explain how the valves
work.
Suffocation, Blinding and Burning Hazards:
Never test an anhydrous ammonia hose valve unless you
are absolutely certain the hose and valve bodies are
empty, or both hose ends are securely connected to sealed
systems.

A59.Bleed Valve(s) (Not Shown)
Suffocation, Blinding and Burning Hazards:
Be up-wind when operating a bleed valve.
Wear chemical gloves when operating a bleed valve.
Wear goggles when operating a bleed valve.
Do not place your body or head in front of the orifice.
Follow a check-list when operating a bleed valve.
Open a bleed valve slowly.
Hose valves typically have bleed valves. Have the
hose provider explain exactly what is bled by each
bleed valve.
The purpose of a bleed valve is to perform a
controlled release, via an orifice, of any fluid or gas
trapped in the closed line prior to disconnect at a
nearby Acme fitting.
A single bleed valve may be located on the inlet or
outlet side of the valve, and only protects that side of
the circuit when the valve is closed. More rarely, a
shut-off valve has bleed valves on both sides of the
valve. An older ball valve may have a bleed valve for
the ball itself.
A60.Withdrawal Valve
In field operations, this valve is
opened first, and
closed first.
Ammonia Release Hazard:
Never open the withdrawal valve unless:
a. all other valves and bleed valves, are closed, or;
b. the applicator is configured and ready for use.
Always be on the upwind side for valve operation.
Always open slowly.
Always check for signs of release when opening this valve.
The withdrawal valve is the application outlet valve.
It is usually located on the tank top, but may be
located on the bottom. It is color coded red or
orange.
A61.Pressure Gauge (Not Shown)
This gauge reports the pressure (usually in psi) of
the NH
gas at the top of the tank. The reading

Anhydrous Ammonia Release Hazard:
Use only the Great Plains rear hitch for a trailing nurse tank
cart. A custom hitch and/or mount, including any safety chain
anchors, could fail entirely, resulting in a tank cart upset.
Consequences could include a catastrophic release of NH
3
.
At the very least expect a breakaway event and cart damage.
Preparation and Setup
This section helps you prepare your tractor and fertilizer
applicator for use, and covers tasks that need to be done
seasonally, or when the tractor/fertilizer applicator
configuration changes.
Before using the applicator in the field, you must hitch it
to a suitable tractor, inspect systems, level the applicator,
and then hitch a suitable nurse tank to the applicator.
Before using the fertilizer applicator for the first time, and
periodically thereafter, certain adjustments and
calibrations may be required.
Anhydrous Ammonia Exposure Hazard:
NP2540A models: Do not modify the NH
applicator. Designing NH
components is serious engineering. Testing a custom system
could be extremely hazardous (and field PPE
for such testing). Malfunction of a custom system could result
in a major release of NH
systems, selecting and installing
3
gas or liquid.

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 131).
• De-grease exposed cylinder rods if so protected at
last storage.
• Verify that all time-dated components are within their
service lives.

Anhydrous Ammonia Exposure Hazard:
NP2540AA models: Use a tractor with a fully enclosed cab.
A tractor that is not fully enclosed exposes the operator to
substantially more NH
3
vapor, particularly if field
requirements result in downwind turns or downwind passes.
Repeated exposure to NH
3
vapor may exceed PEL
(Permissible Exposure Limits) and also induces olfactory
fatigue (adaptation). Over time, you become less sensitive to
ammonia odor, and may fail to recognize dangerously high
concentrations.
Loss of Control / Public Safety Hazards:
Do not transport on public roads with a conventional or
anhydrous nurse tank hitched to the applicator. Transport with
an anhydrous ammonia nurse tank hitched to an applicator is
illegal in many places. See “Transport” on page 56.

Pre-Application Setup
Complete this checklist before routine setup:
Read and understand “Important Safety
Information”, pages 1 to 17.
Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
Check that all grease fittings are in place and
lubricated. See “Lubrication and Scheduled
Maintenance” on page 140.
Check that all safety decals and reflectors are
correctly located and legible. Replace if damaged.
See “Safety Decals” on page 9.
Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation Chart”
on page 163.
Hitching Tractor to Applicator
This manual presumes the following (recommended)
operations sequence:
1. Hitch tractor to applicator for transport (next page)
2. Transport applicator separately from nurse tank:
page 56
3. Hitch nurse tank to applicator at field:
page 74
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. Normally the lower arms engage pins in the lower
holes of the applicator’s three point lugs. You may
use the upper holes if necessary.
3. Set tractor sway blocks to minimize side sway. Set
tractor hitch lift control to Float.
4. Back tractor up to applicator. Align lower links with
the lower hitch clevis on applicator. Adjust hitch
bushings and spacers supplied with applicator
according to the category of your tractor. Lock pins in
place.
5. Set hitch for Depth Control mode.

NP2540AA: Emergency Shut-Off Rope
This part of hitching requires operating the emergency
shut-off valve. If the applicator was correctly shut down
and discharged after last use, there is no anhydrous
ammonia liquid in the system, and only small amounts of
vapor, at low pressure. If the applicator was improperly
shut down, checking the emergency valve could be
hazardous.
Possible Chemical Hazard:
Wear your NH
points. Residual NH

About Bleed Valves:
The purpose of a bleed valve is to perform a controlled
release, via an orifice , of any fluid or gas trapped in
the closed line prior to operating other valves or
uncapping at a nearby Acme fitting.
If the line is discharged, opening the valve may have no
result, or may release a small amount of NH
low pressure. If there is a low pressure release, leave the
valve open at the current position. Move away up-wind.
Return when the release concludes.
If the line was not discharged, opening a bleed valve
may release NH

Rope Function Hazard:
Avoid rope routes at or below plumbing centerline.
Routes below plumbing center-line cannot operate the valve.
Routes at plumbing center-line may fail to operate the valve.
Avoid rope routes that are too vertical.
A rope running at a high angle may fail to fully close the valve.
On a 2-point applicator, the tractor cab may be high
enough to provide the angle needed. On a pull-type
applicator, it may be necessary to route the rope(s)
over the transport rest.

open it.
7. Locate the emergency rope .
8. Inspect the attachment of the rope to the valve
handle, and the rope itself. Replace the rope if cut,
frayed or worn. If the handle connection is not
secure, take corrective action.
9. Uncoil the rope. Remove any knots.
10. Route the rope forward and above the plumbing
center-line (but otherwise near center-line), toward
the tractor cab. Avoid having the rope rest on or rub
against any applicator or tractor parts that could
cause a snag or abrasion. Avoid running too far
sideways, or operation may bend the handle.
11. Route the rope into the tractor cab.
12. Test each rope. Make sure each rope can quickly

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.

Hydraulic Pump Hookup (Option)
The hydraulic pump used has a 7 gpm (23 liters/min.)
motor. If the tractor used does not have the capabilities
to adjust the remotes down to this flow, then a Hydraulic
Flow Divider Kit must be installed so that flow can be
controlled to prevent operating the pump at excessive
speeds. See a Great Plains dealer for more information.
If the tractor has only one circuit capable of continuous
flow or only one capable of adjustable continuous flow,
reserve that circuit for the pump, and use another for the
main applicator functions.
1. Connect the pump hydraulic hoses to suitable tractor
remotes.
Refer to Figure 13
2. The pressure hose coming out of the tractor remotes
must be connected to the motor inlet port:
“I”, Base end on hose label),
and the return line connected to the motor outlet:
“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 76 for setting flow rate.
Raise Parking Stands
Refer to Figure 14
Heavy Object Hazard:
Use the lifting handle . Push leg against frame while raising
or lowering. The leg weighs approximately 45 pounds (20 kg).
The leg could cause injury if you lose control of it while
raising or lowering.
1. Use tractor 2-point hitch and the fold/lift circuit to
slightly raise the applicator. See “Raising/Lowering
Applicator” on page 48.
2. Remove cotters from pins .
3. Grasp the lifting handle. Use an assistant or shoulder
to hold leg against frame and inside flanges.
4. Remove the pins .
5. Lift or lower the stand straight up or down.
6. Re-insert pins. Secure with cotters.

Leveling Applicator
During initial setup and periodically throughout the
season, check that the applicator runs level. When
applying fertilizer, the top of the main frame should be
parallel to the ground, and level left to right.
Set Application Depth
Before checking or correcting side-to-side or
front-to-back level, set the application depth (which is
controlled by tool bar height).
The Nutri-Pro
application at:
0to6inches(0to15.3cm)
For adjustment, see “Vantage I Coulter Adjustments”
on page 88.
To check level, lower the applicator into the ground in
representative conditions.
Front-to-Back Level (Spacers)
The rear lift-assist assembly must be set to match the
gauge wheels and 2-point hitch in front. Lift-assist
lowered height is controlled by (provided) spacers on the
lift cylinder rods.
To set:
1. Lower applicator until lift assist wheels are just off
the ground.
2. Raise applicator until wheels touch ground just firmly
enough to resist spinning.
Refer to Figure 16
3. Insert a combination of spacers to fill the space on
the rod between the cylinder end and clevis.
4. Raise and lower applicator. Pull forward and check
coulter depth and front-to-back level. Adjust spacers

Meter / Variable Rate Setup (Option)
This topic presumes that the Nutri-Pro® applicator has
one or more Raven SCS 450 consoles, speed radar, flow
meter, pressure sensor, section control valves, and, for
anhydrous models, single or dual Raven AccuFlow™
metering system. It also presumes that the console has
been installed in the tractor cab per “Console
Installation” on page 175.
If the Nutri-Pro® applicator has dealer- or user-provisioned
controller or metering, carefully follow supplier
documentation for installation, setup, use and maintenance.

system. Great Plains cannot assume any liability for results
with equipment not supplied by Great Plains.
Before first field use of the SCS 450, it must be
programmed with data specifying the system
configuration, consisting of various “CAL” numbers and
user elected “RATE” numbers. See the Raven SCS 450
manual for display interpretation, and see the manual or
the Calibration Card for the keystroke sequence for
setting each of these values.
This data is retained as long as the SCS 450 remains
connected to battery power. If power is removed for
electrical work, long term tractor parking or welding, the
data is lost and must be re-entered.

SCS 450: BOOM CAL
Anhydrous models without section control have one
“boom section” (BOOM 1, whether single- or
dual-cooler). The BOOM CAL number is simply the
applicator swath on single-section applicators. See the
table on page 44.
Hydraulic pump models and anhydrous models with
section control have three boom sections. See the table
on page 44.
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.
The Great Plains Raven AccuFlow™ and SCS 450
Two-product applicators using two SCS 450 consoles
bundles do not include a speed sensor, nor the cable
necessary to connect a Raven-compatible sensor or
radar to the SCS 450 See page 148 for an available
radar kit. See page 166 for harness cables available
from Great Plains or Raven.

manual).
Obtain this number from the tag affixed to the valve.
Enter it into the SCS 450 and record it on the Calibration
Card.
SCS 450: PRESSURE CAL
Conventional Liquid Fertilizer only:
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 material consumed (as
measured by the flow meter) is continuously subtracted
from this number, and may be used to signal a low tank
alarm. The number needs to be re-entered at each refill.
SCS 450: TIME
Optional. The SCS 450 (which is always in 24:00 hour
time format) defaults to 00:00 (and resets to that after 10
days of inactivity). You may use this menu to set the
actual time.

Spill hazard/Tank damage risk:
Periodically check the tension of the straps for the fertilizer
tank. Strap tension will change as outside air temperature
changes. Adjust tension as necessary to prevent personal
injury or damage to the fertilizer tank.
Operating Instructions
This section covers general operating procedures.
Experience, machine familiarity and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
Pre-Start Checklist
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can
be almost invisible. Use paper or cardboard, not body parts,
and wear heavy gloves to check for suspected leaks. If injured,
seek immediate medical attention from a physician familiar
with this type of injury.
This checklist presumes that the nurse tank is not yet
connected.
Carefully read “Important Safety Information” on
page 1.
Empty the applicator’s 10 gallon wash water tank,
Refill it with fresh clean water.
Review the Material Safety Data Sheet (MSDS) for
the anhydrous ammonia.
Check that all time-dated applicator components are
still within their specified service lives.
Check all plumbing components, hose, tubing and
fittings are in satisfactory working condition.
Lubricate fertilizer applicator as indicated under
“Lubrication and Scheduled Maintenance” on
page 140.
Check all tires for proper inflation. See “Tire
Inflation Chart” on page 163.
Check all bolts, pins, and fasteners. Torque as
shown in See “Torque Values Chart” on page 163.
Check fertilizer applicator for worn or damaged
parts. Repair or replace parts before going to the
field.
Check hydraulic hoses, fittings, and cylinders for
leaks. Repair or replace before going to the field.

FOLD / FIELD Switch
34918
Machine Damage Risks:
Lift/lower (except field lift) and fold/unfold operations are
possible with the hydraulic harness off, but care must be
exercised. It is possible to lower below level, which can result
in row unit ground strikes and dragging.
Fold/Lift Circuit
The fold and lift cylinders share a single hydraulic circuit.
Solenoid valves (controlled by a switch box), one or
more passive valves, and mechanical locks control
hydraulic sequencing.
This system design provides a partial fold, as a single
self-limiting hydraulic operation, during field lift, providing
extra wing clearance in field turns.
If the hydraulic harness is not connected at the hitch, or
the switch box is off, or power is off, most valves default
to an Open state.
FOLD / FIELD Switch
Refer to Figure 19 (depicting the switch in PARK)
This switch is mounted in the tractor cab (page 173), and
connected to the applicator at the hitch. It controls
several solenoid valves on the applicator. It has three
toggle positions and two indicator lamps.
The switch is powered by the tractor. An illuminated
lamp indicates power sent to the harness. The
harness must be connected at the hitch for the
function to be effected.
Switch Positions
PARK
FOLD
UNFOLD
FIELD
All solenoid valves are powered off and are
spring-loaded to flow-open positions.
Use this position only for parking, to save tractor
battery power. With the switch in PARK, any
hydraulic flow to the fold/lift circuit may have
undesired results.
Full fold and unfold sequence is controlled.
Down-pressure is disabled.
During unfold, the inner wings unfold before the
outer wings. During fold, the outer wings fold before
the inner wings. Fold range from fully folded to
wings level (excepting down-pressure) is available.
Outer wings locked.
Inner wing fold restricted to “gull wing”.
Down-pressure available.
Use this position in the field. It engages the
down-pressure circuit for weight transfer.
It provides a partial fold for extra wing clearance in
field turns.

Applicator Locks
The Nutri-Pro® NP2540 Applicator is equipped with
several lock systems, which provide safety and/or
operational functions. Manual locks require operator
intervention for specific tasks. Automatic locks require no
intervention, but you may need to be aware of their
function.
Lift-Assist Lock Channels
Refer to Figure 20
These 11 inch (28 cm) length manual lock channels
are installed on the rear lift-assist cylinders for
adjustments, transport, parking, storage and raised
servicing. The locks are held in place by a bent pin .
Fully raise the applicator (page 48) to install or remove
the channels at the cylinder rods.
When not in use, the channels are stored on tubes on
the caster side faces.
Wing Lock Pins
Refer to Figure 21
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 55.
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.
Solenoid Valves
See “Fold/Lift Circuit” on page 46 for functions
controlled by solenoid valves.

Gradual Crushing Hazard:
Do not rely on hydraulic pressure alone to keep the applicator
raised. Use parking stands (page 40) and locks (page 47)
when working around a raised applicator. The tractor hitch
may settle.
Equipment Damage Risk:
Do not fully fold or fully unfold while lowered. Perform
complete fold and unfold only when fully raised. When
lowered, the wing coulters near the wing pivots may be
damaged by bending or ground dragging.
Raising/Lowering Applicator
Operate the tractor hitch in “position” or “depth” control
mode, regardless of applicator hitch type.
The applicator may be raised and lowered while folded.
Raise For Transport (Folded)
These steps presume an applicator parked or stored
folded, already raised, but on lift-assist locks and parking
stands. No use of the applicator hydraulics is required.
1. Verify that lock channels are installed on the
lift-assist cylinders (page 47).
2. Verify that wing lock pins are installed on the folded
wings (page 47).
3. Raise the tractor 3-point hitch just enough to lift the
parking stand bases off the ground. Set the hitch
circuit to Neutral. Shut off the tractor.
4. Raise the parking stands (page 40).
The FOLD / FIELD switch may be in any position for
lift while folded.

Tip-Over and Crushing Hazard:
Never unhitch without using parking stands, particularly while
folded. A folded applicator without parking stands deployed
may tip forward immediately upon unhitching. Anyone at the
hitch or in the tractor could be seriously injured or killed. The
tractor cab may be crushed.
Equipment Damage Risk:
Although it is possible to fully lower the applicator while
folded, this is not recommended. This can place the full weight
of the machine on the center coulters, exceeding their spring
capability.
If wing lock pins are installed, the FOLD / FIELD
switch may be in any position for lowering while
folded.
Figure 27
Switch for Unfolded Parking
34918
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 47).
2. Verify that the wing lock pins are installed. Wings
unfold during lower if these pins are not in place.
3. Extend the fold/lift circuit to lower the lift-assist
cylinders onto their locks.
4. Raise the tractor three-point hitch until the applicator
mainframe is level front-to-rear, or the front is slightly
higher than the rear. Set the hitch circuit to Neutral.
Shut off the tractor.
5. Deploy the parking stands. Pin them so that the
frame will be level when lowered onto the stands.
6. Start the tractor. Lower the tractor hitch until the
applicator is supported by the parking stands.
Lower While Unfolded
These steps presume that the applicator is presently
folded with lift-assist lock channels installed, and parking
stands deployed, and that the intention is to park, store
or service the applicator. For field lower and field
adjustments, see topic “Field Lower” following.
1. Perform a Lower While Folded operation (page 51).
2. Set the lift/fold/circuit to Neutral or Float.
3. Remove the wing lock pins (page 47).
Refer to Figure 27
4. Set the FOLD / FIELD switch to
FOLD / UNFOLD
This arrests unfolding at wings-level.
5. Extend the fold/lift wing to unfold the wings, until
wings-level.
6. To keep all coulters off the ground when unfolded
and lowered, crank the gauge wheels to full
extension.
7. If the tractor hitch is raised, lower it until the
applicator rests on the parking stands at front.
8. Set the FOLD / FIELD switch to
FIELD
This allows the wings to move below level.
9. Extend the fold/lift wing to further unfold the wings
until the gauge wheels touch the ground, then set the
circuit to Float (to relieve pressure at hitch hoses).
The counterbalance valve holds the inner wings at
their current position.
10. Set the FOLD / FIELD switch to
PARK

Figure 28
Switch for Field Lower
34918
Field Lower
These steps are for lowering in the field after initial
line-up and after turns. Lift-assist lock channels
(page 47) are presumed to have been replaced by
spacers (page 41). The down-pressure/weight transfer
system (page 91) is presumed to be adjusted.
The key objectives for an optimal lowering are:
• avoid side loads on coulter discs or tines by avoiding
lowering with drooped wing tips, and
• avoid tine plugging by avoiding any reverse motion
of the tines at the ground.
Being in slow forward motion during lower avoids both of
these risks. The following instructions presume a
lowering while stationary.
Refer to Figure 28
1. Verify that the FOLD / FIELD switch is set to
FIELD
2. Check that wings are partially folded in field lift, or at
least level. If they are drooping, retract the fold
cylinders to correct.
3. Lower the tractor 3-point hitch to the preset field
height. Set the hitch circuit to Position or Depth
Control.
4. Extend the fold/lift circuit to lower the wings below
level into down-pressure mode, and to retract the
lift-assist cylinders to their spacers.
You may lower the hitch and lift-assist simultaneously,
but avoid lowering the lift-assist before the hitch.
5. Pull forward.
6. Leave the fold/lift circuit active in the lower/unfold
position, to supply oil to the down-pressure system.

Refer to Figure 35
Electrocution and Overhead Collision Hazards:
Do not fold with switch in FIELD position. In FIELD, the
outer wing sections cannot fold. The folded applicator would
be over 21 feet (6.2 m) high. This dramatically increases the
risk of electrocution from overhead lines, with or without
direct contact. It is also too high for safe transport.
Refer to Figure 34
3. Raise the hitch.
4. Retract the fold/lift circuit to simultaneously raise and
fold the applicator. Observe the fold sequence. Lift
and fold do not start and end at the same time.
If an abnormal fold is detected, set the fold/lift circuit
to Retract, then Neutral at wings level. Troubleshoot
the problem.
5. Set the fold/lift circuit to Neutral.
6. Remove spacers (page 41). Install lift-assist cylinder
locks (page 47).
7. Insert wing lock pins (page 47).
8. Extend fold/lift to lower lift-assist cylinders onto lock

NP2540 Table of Contents Index Operating Instructions 56
Braking and Loss of Control Hazard:
Do not exceed 20 mph (32 kph).
Loss of Control Hazard:
Never tow a 2-point applicator that weighs more than 67% of
the tractor (transport tractor must weigh at least 150% of
applicator). Ensure that the towing vehicle is adequate for the
task. Using an inadequate tow vehicle is extremely unsafe, and
can result in loss of control, serious injury and death.
Tractor weight matters. For field configuration (after
transport), tractor must weigh at least 150% of the loaded
applicator plus any loaded nurse tank. This tractor weight
requirement is substantially higher than for transport.
Transport
Loss of Control Hazards:
Never transport a 2-point applicator unless the tractor is
properly ballasted to provide adequate weight on the steering
wheels. A heavy 2-point applicator can dangerously reduce
steering control. Check your tractor manual for ballasting
requirements. A normal turn could result in an accident and
serious injury or death.
Do not transport applicator with material in on-board tanks.
Add liquid fertilizer at field. Full tanks add 7200 pounds
(3270 kg) to the weight of the applicator, almost all of it borne
by the tractor 2-point hitch. This can substantially reduce
tractor steering and does increase braking load. The
applicator rear casters are free to swivel, and cannot provide
protection against under-steer in turns.
Loss of Control Hazard:
Never use the applicator to tow a nurse tank on public roads.
Tow the tank to the field with a separate vehicle. The
applicator cannot provide sufficient lateral control of a
trailing cart at highway speeds. The total weight of the train
can also easily exceed the steering and/or braking capability
of the tractor. A tank upset could occur during normal
highway maneuvers. The resulting accident or spill could
cause serious injury or death.

Spill hazard/Tank damage risk:
Periodically check the tension of the straps for the fertilizer
tank. Strap tension will change as outside air temperature
changes. Adjust tension as necessary to prevent personal
injury or damage to the fertilizer tank.
Transport Steps
Know your applicator weight. See “Specifications and
Capacities” on page 155 for approximate weight of
various configurations.
If tractor capabilities are marginal, check actual weight of
applicator at a scale.
1. Check that fertilizer applicator is securely hitched to
a sufficient tractor (page 35)
2. Verify correct operation of lights.
3. Raise fertilizer applicator (page 49).
4. Install lift cylinder locks (page 47).
5. Fold applicator if unfolded (page 53).
6. Plan the route. Avoid steep hills.
7. Always have lights on for highway operation.
8. Do not exceed 20 mph (32 km/h). Comply with all
national, regional and local laws when traveling on
public roads.
9. Remember that the fertilizer applicator may be wider
than the tractor. Allow safe clearance.
10. Transport slowly over uneven or rough terrain.

Final Applicator Setup
Prior to hitching nurse tank and/or loading materials,
make and check final applicator adjustments. This could
include:
• Coulter (Option) depth and castering, page 84.
• Tine condition.
• Sealer adjustments (NP2540A), page 86.
• Application depth, page 88.
• Application Rate, page 94.
• Row cleaner adjustments, page 87.
• Make a dry run to check applicator functions, running
depth and sealing.
For nurse cart hitching, the applicator may be raised or
lowered, folded or unfolded. However, raised and folded
hastens departure if any nurse tank problems are
discovered before cart hitching.

Blinding, Choking and Respiratory Hazard:
Never look directly into an ammonia hose or fitting.
Use a mirror. Always assume that ammonia is present in the
system. There are many ways it can hide, and surprise you
later. See “Avoid Trapped Anhydrous” on page 114.
6. Using a hand mirror, inspect the gasket inside the
fitting . If there is no sign of ammonia, and no
odor, you can remove the gasket by hand for closer
inspection.
This gasket makes the liquid-tight seal between the
hose and break-away coupler. Inspect it for a smooth
face, no cracks, chips or weathering, and no sign of
permanent compression. Replace gasket as needed
for a tight seal.

to any clamps or caddies provided.
Do not clamp or tie the hose within 3 feet (92 cm) of
the breakaway coupler inlet .
Allow at least 13 inches (33 cm) slack in the hose
within the first 3 ft. Do not allow excess slack that
could allow the hose to snag or drag on the ground.

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

NH
: Dry Run
3
Before activating the NH3 delivery, cautious practice is to
make one dry run pass, including a turn in each direction.
This assures that tine depth is set correctly, hydraulics
are working correctly, the nurse tank cart is tracking
without issue, proper slack exists for all hoses and
harnesses, and the meter console is reporting correct
field speed.

NH
: Pass Planning
3
If field requirements permit, you can minimize exposure
to NH
vapor with the following recommendations:
3
Refer to Figure 44
• Check the wind direction.
• Plan passes to be cross-wind and turns up-wind.
• Plan first pass on down-wind side of field.
• Choose your first pass to allow you to be up-wind
while operating valves at the nurse tank and
applicator. Opening the emergency shut-off
valve typically requires climbing on the
applicator from the right. Starting with the wind from
the right is optimal.
Anhydrous Ammonia Exposure Hazard:
If field requirements result in any down-wind operations:
Use only a tractor with an enclosed cab.
Have an escape route (up-wind turn) available for all
down-wind operations.
Conduct end-of-pass operations to minimize
above-ground releases.
Be mindful of the risks of olfactory fatigue. You can
“get used to” the odor and fail to notice when
concentrations get dangerously high.
NH
: Start of Pass Planning
3
Ideally, you want NH
right at the start of a pass, with the tines already in the
ground. This minimizes atmospheric releases.
Depending on wind direction, tractor capability, available
headlands, and field conditions, there are several ways
to start each pass.
A. Capable Tractor:
Lower applicator into ground at start of pass. Pull
forward to set them to operating depth. Start meter
flow. Do not start moving until flow divider pressure
gauge nears typical operating value.
B. Headlands Available, Any Tractor:
Lower applicator to ground some distance ahead of
the application area. Move forward slowly. As tines
enter ground, start meter flow.
C. No Headlands, Marginal Tractor:
Lower applicator to ground at start of pass. Start
forward movement, then meter flow. Move slowly
until console rate display nears target rate.

NH3: Possible Chemical Hazard:
Anhydrous ammonia is now flowing into the ground. Some
routinely escapes to the atmosphere. Check for leaks. Take
action if strong odor is detected or a leak seen. Turn up wind.
Turn off flow. Check gauges from tractor cab. Engage
emergency shut-off valve if a leak is detected.
Minor odor during application is normal, particularly if the
tractor cab is ever down wind of recent passes.
Strong or irritating odor indicates a problem. Conditions
may not be suitable for application (soil too dry, cloddy
and deeply cracked, for example), or there may be a
system problem.
2019-04-12 Table of Contents Index 417-459M
a. This 5 psi correlation is only true under no-flow conditions. When NH3 application begins, the pressure reading at the cooler gauge drops,
due to the reduced temperature of the cooled fluid, and pressure losses due to flow in plumbing.
Page 71
NP2540 Table of Contents Index Operating Instructions 67
Choking Hazard:
Never raise a recently operated applicator when you are
down-wind of the applicator. Be facing up-wind or turn
up-wind if it is necessary to raise a working applicator. Wear
your goggles. A substantial amount of anhydrous ammonia is
rapidly released if you do not allow time for it to bleed off
underground. The concentration could be high enough to
cause irritation, breathing difficulty or asphyxiation.
A31
A31
A42
Ammonia Vapor Release Occurs at Turns:
Avoid down-wind turns.
Do not raise for turns if unprotected individuals or sensitive
livestock are immediately down-wind of the turn. Stop instead.
Turning off NH
3
flow prior to raising for turns does deplete
some of the liquid ammonia in the delivery lines, but not all of
it, and considerable vapor remains. At turns, there will be
some release of NH
3
vapor, and possibly some NH3liquid.
Be prepared for it. Minimize exposure to yourself and others.
Turn up-wind immediately if a hazardous concentration of
fumes reaches the tractor cab.

Ball Valves: Trapped NH3 Hazard:
Avoid routinely closing ball valves (other than the nurse tank
withdrawal valve) with liquid NH
3
in the lines. Fluid is
trapped in the line above the valve, may trigger relief valves,
and can get trapped inside the valve ball unless it has a bleed
port (not yet common on nurse tank hoses). See “Avoid Line
Traps” on page 114 and “Avoid Ball Traps” on page 115.
A typical ball valve can trap enough NH
3
to make a room the
size of a two-car garage uninhabitable (concentrations above
IDLH in moments). When the ball valve is later opened, while
warm, the NH
3
is expelled at high pressure. If the line is
pointed at your face, you could receive a fatal exposure.

b. Suspend application per “NH3: Suspending
Application” on page 67.
c. Put on your chemical gloves.
Be wearing your goggles.
d. Carefully approach the nurse tank from up-wind.
Expect some ammonia odor, but if it is extremely
strong, there may be an above-ground release in
progress due to malfunction or part failure. If so,
remain clear until the release subsides.
e. When safe to do so, shut off the nurse tank
withdrawal valve .
f. Re-enter the tractor cab.
g. Turn MASTER switch ON.
h. Resume field application until reported rate begins to
fall. Increase rate to maximum (to fully open Control
Valve ).
i. Continue field application until both cooler and
divider pressure gauges read zero.
j. Facing into the wind, raise the applicator and stop.
k. Set the MASTER switch to OFF.
l. Wait at least 1 minute for row line vapor to dissipate.
m. Turn so that the wind is directly from the right.
n. Open all bleed valves. Standing up-wind of each,
and making sure orifices point away from you, slowly
open bleed valves at:
• nurse tank hose inlet end
• nurse tank hose outlet end
• breakaway valve ( or , whichever is safer)
• cooler temperature gauge .
o. Close all remaining operating valves:
• nurse tank hose inlet end
• nurse tank hose outlet end
• emergency shut-off valve .
p. Wait at least one hour before moving applicator to
any spot near unprotected people or livestock. It will
continue to out-gas ammonia vapor for some time.

Upon Event: Probable Chemical Hazard:
A 60cc NH
3
liquid release to air has already occurred. Assume
a major release is also in progress or imminent. Act
accordingly. Request assistance from trained experts rather
than risk blindness, disfiguring/disabling injury or death.
A breakaway event is most likely due to a major equipment
failure (such as nurse tank running gear fracture), or a gross
operator error (such as towing/turning too fast, or departing
level ground). These cases can result in an immediate serious
spill, or result in a damaged tank at risk of leak at any time.
Even in the case of a basic operator error (such as movement
with only the nurse tank hose connected) both applicator
systems and nurse tank hose(s) at breakaway are fully charged
with liquid NH
3
, right up to the checks in the breakaway
halves. The nurse tank side is under full tank pressurization.
The applicator hose(s) may be under pressure.
This was an unplanned event. Wind direction may not be
favorable for discharging and re-coupling. If the wind is light
or calm, do not attempt to bleed the breakaway coupler
halves. Your field PPE

is not sufficient for the releases
necessary.

: Breakaway Event
3
Initially treat a breakaway coupler separation event as
you would any other field emergency. Perform the steps
at “Ammonia Emergency Action” in the “Using
Anhydrous Ammonia Safely” manual (407-551M).
Only then consider performing the steps on this page.
Although the breakaway coupler is designed to separate,
such breakaways are not routine events
.
Upon a breakaway, what to do about the breakaway
coupler itself is the last consideration. Priorities are:
1. Protect: Perform basic field emergency action, which
may included summoning emergency responders if
a major release is in progress, or the nurse tank is
tipped over, or is otherwise at risk of a major release.
2. Assess: If the nurse tank appears intact, sound and
stable, determine the cause of the breakaway. It is
unlikely to be something simple that will allow a
timely re-coupling and resumption of application.
If, and only if, the nurse tank is safe to approach, take the
next steps to discharge both sides of the breakaway.
Discharge Applicator:
3. Perform the steps at “NH3: Stopping Application”
on page 68. Remain up wind and clear of nurse tank
while doing this.
4. With the orifice pointing away from you, and
down-wind, slowly open the coupler bleed valve
at the applicator half of the breakaway coupler(s). If
you closed the emergency shutoff(s) after
breakaway, each bleed will release liquid NH
pressure, most likely as a spray
.

Discharge Nurse Tank Hose(s):
5. Position the tractor and applicator near the nurse
tank. Stop up-wind of the tank, but slightly cross-wind
of the tank (so that you are not exposed to residual
applicator fumes while working around the tank).
Face the tractor into the wind.
6. From up-wind, approach the nurse tank.
7. Close the nurse tank withdrawal valve .

Before Re-connection: Elevated Exposure Hazard:
Exercise extreme care. Even if the nurse tank is undamaged,
sound and upright, a breakaway event is not a normal re-hitch
situation. A substantial NH

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

. Open the valve very
slowly, just until some fluid appears. Leave the valve
just slightly open.
12. Walk away, up-wind. Stay away until the release
concludes. Carefully open bleed valve completely to
confirm hose is discharged. For dual-cooler, repeat
step 9 through step 12 for the other hose.
13. Close all breakaway bleed valves ( x and ),
and any nurse tank hose valves . Disconnect the
nurse tank half of the breakaway coupler at the
Acme coupler .
14. Correct the cause of breakaway, only if trivial to do in
the field.
15. Consult the breakaway manual for re-coupling
instructions.

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.

Liquid Operations
Operations for anhydrous nitrogen fertilizer begin on
page 58.
Liquid: Filling On-Board Tanks
The tanks may be loaded from the quick-fill inlet, or from
the lids (page 73).
If the fertilizer solution has any tendency to settle,
sediment, gel, coagulate, precipitate or stratify, load
material immediately prior to application. The tank
system has no agitators for sustaining suspensions.
Apply fertilizer soon after material loading. Clean out
unused materials promptly. Fertilizer allowed to remain in
the tanks for an extended period can settle, resulting in
excessive or insufficient concentrations during
application. System plugging can also occur.
1. Hitch the applicator to a tractor. Filling an unhitched
applicator is not recommended, as it can increase
parking stand loads above the bearing capacity of
the soil.
2. Inspect the tanks from the lids.
3. Drain excess condensation from the tank, so that
this water does not dilute the material to be loaded.
See “Material Clean-Out (Liquid)” on page 127.
4. Flush the tank if there is other residue present.
NH
: Tank Quick-Fill

Refer to Figure 49
5. Position the applicator on level ground, or tanks may
fill unevenly.
6. Connect the nurse-tank hose to the quick-fill
coupler located at the left end of the left tank.
Lock hose in place with cam-lock levers.
7. Open the discharge valve ( , not shown) of each
tank to be filled. If filling must be performed on
unlevel ground, fill one tank at a time.
8. Set the selector valve to “FILL” (handle arrow
pointing forward, toward elbow from inlet).
9. Open shut-off valve at quick-fill coupler.
10. Open any supply valve and fill tanks. Tanks are
marked with fill levels.
11. Close valve at supply, then quick-fill coupler, and
disconnect the nurse tank hose.
12. Set selector valve to OFF, or to PUMP if applying
immediately.

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.

Liquid: Tank Lid Fill
Employ two persons for top fill; one to secure the hose at
the tank, the other to control a supply line shut-off valve.
These steps presume completion of step 1 through
step 5 on page 72.
Refer to Figure 50
13. Close selector valve (or set to PUMP; there is no
risk of material leakage through the boom until the
pump is operating).
14. Open both tank discharge valves to the selector
valve, if cross-filling from one tank to the next is
desired.
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

hitching.
Refer to Figure 51
2. Bring the applicator rear hitch tongue and nurse tank
cart tongue into close proximity (a few inches).
3. Push down on the red tongue release handle .
This frees the applicator rear hitch tongue to
extend 7 inches (17.8 cm) to the rear, and 9 inches
(23 cm) to either side, to assist with cart tongue
alignment.
4. Align the cart clevis hitch with the applicator pull
bar. Insert and secure the 1 inch (2.6 cm) hitch pin.
5. Securely attach the cart’s safety chain(s) to the
hitch chain anchor(s) .
6. Optionally re-seat the applicator rear hitch tongue, at
this time, by using the tractor to move the applicator
backward several inches, until the latch on the hitch
re-engages.
Liquid: Making Nurse Tank Connections
1. Close shut off valves on all hoses of both tank
and applicator .
2. Route tank supply hose to applicator inlet .
Allow ample slack for tight field turns and uneven
ground. Do not leave so much slack that the hose
can reach the ground.
3. Remove plug from applicator inlet, and any cap on
tank supply hose.
4. Inspect and clean connector fittings.
5. Mate connectors of tank and applicator supply
hoses. Fold cam levers forward to lock. Leave valves
closed.

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).

perform initial setting per page 100.
Liquid: Prime the Ground Drive System.
10. Wearing gloves, manually rotate the ground drive
wheel until material appears at the tines.
Begin field operations.
The pump automatically operates when the applicator is
lowered to ground contact and in motion. The pump
automatically stops when the applicator is raised for
turns.
Liquid: Hydraulic Drive Start-Up
Prior to first use, determine the hydraulic remote circuit
flow rate setting per the procedure on page 104.
11. Set console MASTER switch OFF.
12. Set console POWER switch ON.
13. Select FLOW CONTROL RATE1 or RATE2 as

14. Set console BOOMS
15. Set the flow rate for the hydraulic remote circuit as
established by the procedure on page 104.
16. 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.
17. Set the MASTER switch ON. Check for material flow
at the tines. Prime second hydraulic pump as
required.
18. Begin field operations. Monitor the fertilizer pressure
gauge (or PSI display on optional console).
Liquid: Field Operations (Either Pump)
19. Monitor the fertilizer manifold pressure (gauge or PSI
display on optional console).
20. Mind the fertilizer tank levels while planting, both to:
a. confirm expected consumption rate, and;

planting, apply it to the last field planted.
22. Clean out fertilizer system per page 127.
a
switch 1 ON.
Liquid: Pauses and Turns
Ground Drive Pauses and Turns
When the applicator is stopped, or lifted, the pump stops.
The boom is still pressurized, but this bleeds down to
8 psi very quickly (seconds), at which point the nozzle
clamp check valves close off flow to the rows.
Hydraulic Drive Pauses and Turns
If the applicator has the optional hydraulic drive system,
pauses cause the speed sensor to report zero speed,
which causes the console to close the flow control valve.
Set the pump hydraulic remote to Float if stopping for
and extended period.
For turns and field moves, set the MASTER switch OFF
to avoid material loss. If the factory configuration of the
plumbing has been modified for section control, use the
BOOM switches as desired for point row applications.
a. The standard configuration uses only Valve 1. If optional section control is installed, also engage BOOMS switches 2 and 3.

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 hydraulic
a
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.

Liquid: Fertilizer Operation
For an aftermarket pump system, consult the pump or
system documentation. These pages describe the
available Great Plains systems. See page 31 through
page 32 for callout references.
Liquid: Ground Drive Operation
The piston pump is ground driven. When the
applicator is lowered and in motion, the pump operates,
and fertilizer is applied based on the drive Range
sprocket, and pump adjuster dial setting .
Liquid: 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).
Liquid: 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.
Liquid: 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
3. On suitable ground, raise the applicator.

Liquid: Monitor Operation (Option)
Refer to Figure 52
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.
Liquid: Starting Application with Console
1. Enter the tractor cab.
Refer to Figure 52

lowered) and begin first pass.
See SCS 450 manual for monitor operation details.
a
on to
Suspending Application
With the hydraulic drive pump option, material continues
to flow if the implement is raised while in motion. To
conserve material and prevent unintended application,
set the MASTER switch to OFF when raising.
When stopping, operating the MASTER switch is not
usually necessary, if the console has an active speed
sensor data source.
If suspending application for more than a minute, also
set the pump motor hydraulic circuit to Float.
No console actions are required to suspend application
with ground drive (preset or variable rate).
Liquid: Stopping Application
1. Ground Drive: If possible, plan final passes so that
they occur prior to tank run-out. This keeps the pump
wet. If you do exhaust the material, refill with water.
2. At completion of application, apply almost all of the
remaining fertilizer on the last field. Refill the tank
with clean water.
3. Set application rate to maximum to shorten the
remaining steps:
• Ground Drive: Exchange the ground drive
driving sprocket to obtain High Range
(page 100).
• Ground Drive: Set the pump dial to 10
(page 101).
• Hydraulic Drive: Set the console (Option) for
maximum rate.
Piston Pump Damage Risk:
When configuring the ground drive pump for high rates, check
the chart, slide chart or CDS-John Blue web calculator to
determine the maximum field speed that stays at or below the
pump’s maximum rated rpm.
4. Apply the water to the final field to flush system.
5. Close shut-off valves on both sides of all hose
connections.

Anhydrous Coulter Application Depth
Refer to Figure 53 and Figure 54
Tine release depth is set by tool bar height above
the ground, coulter shank height and tine height .
Chemical Hazard:
Adjust height dry. Make adjustments before charging the
metering system with anhydrous ammonia, or after thoroughly
discharging the system. With the tines out of the ground, there
could otherwise be releases of ammonia at dangerous
concentrations.
Tool bar height is controlled by the tractor hitch in the
center section. Wing tool bar height is set to match the
center using a crank-assisted manual adjustment.
Tine height is adjusted at the mount . This requires
adjustment as the coulter blades wear. Loosen the nuts
on the U-bolts . Lower the shank and re-tighten.
S/N C1083J and above - Tines are to be installed as
high as possible on the tine mount and within
the back of the blade.
Design coulter operating depth is 3 to 7 in (7.6 to 18 cm).
Operation below 7 in (18 cm) is not recommended, as
high rates of disc wear are likely.
Application depth is unaffected by the coulter spring

The standard NH3 coulter spider sealers have three
adjustments. You may need to alter these from factory
settings, based on soil conditions, crop residue and
application speed.
Refer to Figure 57 and Refer to Figure 58
1. Down-pressure: Handles set the arm spring
tension. The adjustment plates have 3 settings.
2. Spacing: The arm weldments have bolt holes
allowing setback positions and spacing positions.
3. Angle: The sealer mount plates have in-line
holes , and slightly offset holes , providing an
angle adjustment.
These adjustments are most easily made with the
applicator raised. The down-pressure adjustment may be
made with rows in the ground, with some extra effort.
Chemical Hazard:
Adjust sealers with rows dry. Make adjustments before
charging the metering system with anhydrous ammonia, or
after thoroughly discharging the system. With the tines out of
the ground, there could otherwise be releases of ammonia at
dangerous concentrations.
Sealer Down-Pressure Adjustment
The following trip down-pressures are available. These
values are per sealer arm, and are with the coulters in
the ground, and arms slightly raised per nominal factory
assumptions (as depicted in Figure 53 on page 84).
With the applicator raised, position has minimal
spring tension.
Handle Slot Down-Pressure
Rear/Lowest
Mid/Medium
Forward/Max.
Sealer Spacing or Setback Adjustment
For in-line (parallel) sealer wheel running, use the center
holes in the mount plates . In-line orientation is
recommended for high-residue fields.
Sealer Angle Adjustment
10° of leading toe-out (20° total) is available by using the
inner center hole of the mount plate and the leading
offset hole . No setback adjustment is available when
using toe-out. Toe-out is not recommended for
high-residue fields.

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 60
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.
Changing force also changes height.

Vantage I Coulter Force
Coulter springs are set to 400 pounds (181 kg).
In normal operation at target running depth, the spring is
at full extension. It compresses briefly as obstructions
are encountered.
• In heavy no-till conditions, you may observe the
springs in compression most of the time. This means
that the blades are not reaching the desired coulter
depth. If applicator weight is available, you can
increase the spring down-force to compensate.
• In light but rocky conditions, the factory spring
setting may be higher than needed. You can extend
blade life by reducing the force at which the blades
ride up over obstructions.
• Applicator weight, in almost all applicator
configurations, is generally sufficient to load the
coulters to the full 400 pound factory setting.
Setting all springs above 400 pounds might require
the optional weight kit with some lighter triple-coulter
configurations.
To adjust the coulter spring:
Refer to Figure 61
1. Raise the applicator and install transport locks.
See “Raising/Lowering Applicator” on page 48.
2. Determine the new spring length desired.
3. Measure the current length of the spring(s) to be

4. Loosen the jam nut .
5. Rotate the adjuster nut until the spring is at the

gauge wheels), resulting in uneven coulter depth
and/or uneven seed depth. If the applicator is
already operating at maximum down-pressure,
reduce coulter depth.

Vantage I Height Adjustment and Castering
Application Height Adjustment
Fertilizer release height is normally at or just above
the ground, and is controlled by three adjustments:
Refer to Figure 61
1. Tool bar height :
This affects coulter depth. The procedure for setting
tool bar height varies with hitch type.
2. Fertilizer arm height :
This affects arm height relative to the coulter.
This adjustment is primarily to compensate for blade
wear.
3. Coulter height :
This affects coulter height relative to the tool bar ,
and is normally not adjusted.
Factory settings:
25 inches above ground at 4 inch coulter depth
7.5 inches coulter shank distance (height)
1 inch release height .
Coulter Height Adjustment
Coulter height is the main control for application height.
Coulters may need to be lowered for rows in tracks.
Coulters applicator-wide need adjustment as blades
wear.
Coulters may also be set for rigid row alignment, or
limited castering.
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 .
Loosen the set screws just enough to allow the casting to
swivel. Tighten the jam nuts. Do not remove the center
stop screw.
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.

Vantage I Coulter Force
Coulter springs are set to 400 pounds. 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.
In heavy no-till conditions, you may observe the springs
in compression most of the time. This means that the
blades are not reaching the desired coulter depth. If
applicator weight is available, you can increase the
spring down-force to compensate.
• In light but rocky conditions, the factory spring
setting may be higher than needed. You can extend
blade life by reducing the force at which the blades
ride up over obstructions.
• Applicator weight, in almost all applicator
configurations, is generally sufficient to load the
coulters to the full 400 pound factory setting.
Setting all springs above 400 pounds might require
the optional weight kit with some lighter triple-coulter
configurations.
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 already operating at
maximum down-pressure, reduce coulter depth.
To adjust the coulter spring:

Weight Transfer Adjustment
Weight Transfer Safety Information
Crushing and High Pressure Fluid Hazards:
This adjustment requires working near the unfolded and
lowered applicator with the hydraulic system active. Assign
two people to this task, one in the tractor, ready to shut down
on hand signal from adjuster or any unplanned event.
High Pressure Fluid Hazard:
Escaping fluid under pressure can penetrate the skin causing
serious injury. Use a piece of paper or cardboard, NOT BODY
PARTS, to check for suspected leaks. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. If an accident occurs, seek immediate medical
attention from a physician familiar with this type of injury.
Crushing Hazard:
Keep body parts clear of wings, row cleaners and coulters
while adjusting. Keep all bystanders well away. You will be
seriously injured or killed if you are caught between lowering
row applicators and ground.
Falling Hazard - Tires Not a Step:
Do not use tires as steps or platforms. At some transfer
settings, cylinders can raise lift-assist wheels sufficiently for
them to spin. Gauge wheels can also be in light or no ground
contact when the weight-transfer system is not active.

Weight Transfer System
Refer to Figure 64
Inner wing fold cylinders can extend, during field
operation, to push the wings down using
mainframe/center weight. Weight transfer is enabled by:
1. Set the FOLD / FIELD switch to FIELD.
2. Adjust the weight transfer valve .
The fold/lift circuit is set to continuous flow (in unfold
mode) to maintain the active weight transfer. This system
is designed for use with tractors having closed center
hydraulics. It is incompatible with open center systems.
Do not set or adjust the weight transfer system if the
outer wings are not level with the inner wings at
unfold. Do not use the weight transfer system to
compensate for unfold stop adjustment issues.
See “Stop Fold Adjustments” on page 133.
Adjust the weight transfer to achieve consistent coulter
depth, while keeping the wings level with the center
section. If insufficient weight is transferred, outside
(wing) coulters may run higher than center section. If too
much weight is transferred, center section may run high.
If adjusted when the tractor is cold, re-adjustment may
be required when the oil warms. Monitor the pressure
gauges during early field operations.
Refer to Figure 64
1. In field conditions, unfold (page 53) applicator.
2. Set FOLD / FIELD to FIELD.
3. Lower applicator(page 48), and set or check
application depth (page 41).
4. Pull forward to put coulters in ground.
5. Put tractor in Park and set parking brake.

Caster Angle Adjustment
Applies to NP2540 only. NP2540BL has fixed angle
lift-assist caster arms.
Your operations may require that the lift-assist tires be
in-row or out-of-row. In-row spacing varies with basic
applicator row spacing. Post-emergence (side-dress), for
example, typically requires out-of-row placement. The
forward caster parallel arm weldments may be pivoted
and pinned for wheel spacing.
Changing Spacing
This is a two person operation. If the applicator frame is
not precisely level, the caster arms may be difficult to
control with one hand.
1. Hitch the applicator to a suitable tractor (page 34).
2. Raise the applicator. Move to a level, and firm or
hard surface.
3. While raised, remove any lift lock channel or spacers
on the lift-assist cylinder.
4. Lower the applicator until the caster tires are just out
of ground contact. Set the fold/lift circuit to Neutral
and shut off the tractor.
5. Remove the hairpin cotter at a caster pin. Have one
person control caster position. Remove the pin.
6. Reposition caster as desired. Insert pin. Secure with
cotter. Repeat for other caster.
Loss of Control and Machine Damage Risks:
Never operate with one or both pins removed, or with pins
installed but not in a caster weldment tube. Always install the
caster pin from the top, in case cotter is lost. If the caster arms
are free to pivot at both ends, they can strike other applicator
components, and directional control is substantially reduced.
This could contribute to machine upset, a road accident,
serious injury or death.
Caster Adjustment
Refer to Figure 66 (depicting the pin in holes 2+a

Fertilizer Rates
Anhydrous Fertilizer Rate
Rate setting for anhydrous ammonia is controlled entirely
by the console. For the Raven SCS 450 available from
Great Plains, see page 42.
Conventional Liquid Fertilizer Rate
Rate setting is materially different for each pump type:
• Ground Drive: rate is positively set by the drive
system and piston pump dial.
• Hydraulic Drive: rate is set on the console.
The console operates a flow control valve. The valve
adjusts the rate up to the peak value available at the
current setting for hydraulic pump rpm.
Make adjustments to orifice plates to provide backpressure, keeping the boom within a specific safe
pressure range that assures consistent delivery.
Rate Setting Steps:
1. Determine the rate (below).
2. Install suitable orifice plates (page 97).
3. Check strainer screen size (page 99).
4. Ground Drive: Set the ground drive Range

Operation and Service manual).
5. Check the manifold pressure and relief valve during
operation (page 100).
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:
If you want to use the slide chart, and have only a metric
rate value, convert it to U.S.customary units:
Ground Drive:
The tables, and web calculator provided expect rates to
be expressed as
[U.S.customary] gallons per [U.S.Survey] acre or
liters per hectare.
The slide chart provided is gal/ac only.
