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

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 5
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.
2012-03-28 Table of Contents Index 407-776M

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.

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.
16
15
14
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
16
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.

407-776M Table of Contents Index 2012-03-28
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 .
38
23. Gauge Protector
Ground Drive Option: This fitting transmits manifold
pressure to the pressure gauge , and protects the
24
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
38
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
32
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,
25
material is jettisoned at this tube. If you observe
dumping, check the pressure and review the orifice
38
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
29
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
24
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).
30
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.
2012-03-28 Table of Contents Index 407-776M
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
36
caps .
39
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
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.

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
2
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.

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.

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.

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.
