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 indicates an imminently hazardous situation
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 indicates a potentially hazardous situation
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 indicates a potentially hazardous situation
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.
Be Familiar with Safety Decals
Read and understand “Safety Decals” on page 8,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

NP30L or NP40L Table of Contents Index Important Safety Information 2
Use Safety Chains (Pull-Type only)
Use safety chains to help control drawn machinery should
it separate from tractor draw-bar or trailing nurse tank
hitch.
Use chain with a strength rating equal to or greater than
the gross weight of towed machinery.
Attach implement chain to tractor draw-bar support or
specified anchor location. Attach nurse tank chain(s) to
anchors provided on implement. 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.
Wear Protective Equipment (PPE)
Waterproof, wide-brimmed hat
Waterproof apron.
Face shield, goggles or full face respirator.
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 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.
Wear clothing and equipment appropriate for the job.
Avoid loose-fitting clothing.
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.

Page 7
NP30L or NP40L Table of Contents Index Important Safety Information 3
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 at other remotes,
and shutting down tractor before connecting,
disconnecting or inspecting 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 assistance
from a physician familiar with this type of injury.
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.
2018-10-10 Table of Contents Index 407-313M
Page 8
NP30L or NP40L Table of Contents Index Important Safety Information 4
Tires Not a Step
Do not use front caster tires, gauge wheel tires, 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 front caster wheels can be in poor ground contact at
any time, even with the fertilizer applicator lowered in the
field. They can appear to be in ground contact, and spin
easily, in multiple conditions.
The lift-assist tires can be in poor ground contact, or out
of ground contact, whenever the fertilizer applicator is
lowered.
Remain Clear of Overhead Lines
If the fertilizer applicator contacts a power line, lethal
voltage may be present on all metal parts. At higher
voltage, the applicator does not need to be in line contact
for the hazard to exist. Maintain at least 10 foot (3 m)
clearance.
Electrocution can occur without direct contact between
the energized fertilizer applicator and a person near the
fertilizer applicator.
Watch for sagging, damaged or low electrical lines. The
folded fertilizer applicator could contact lines lower than
13 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.

NP30L or NP40L Table of Contents Index Important Safety Information 5
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.
Do not tow a pull-type or 2-point implement or nurse tank
that, when fully loaded, weighs more than 1.5 times the
weight of towing vehicle.
Do not transport a 3-point implement 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 121.
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.

commencing maintenance.
Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on
fertilizer applicator.
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 implement
before operation.
Safety At All Times
Thoroughly read and understand the instructions in this
manual before operation. Read all instructions noted on
the safety decals.
Be familiar with all fertilizer applicator functions.
Operate machinery from the driver’s seat only.
Do not leave fertilizer applicator unattended with tractor
engine running.
Do not stand between tractor and implement, or
implement and nurse tank, during hitching.
Keep hands, feet and clothing away from power-driven
parts.

L30. Strainer
This fitting contains an 80 mesh screen for filtering
large particles and coagulates in the fertilizer,
preventing blockage at the orifice plates . See
page 90 for alternative screen sizes and page 104
for maintenance.
L31. Ground Drive Pump
The CDS-John Blue NGP-7055-K has a capacity of
34 gallons/minute (129 liters/minute). See the
CDS-John Blue NGP Pump Parts and Instructional
manual (12-M-43) for maintenance.
L32. Pump Adjustment Dial
(ground drive implements only)
This 0-to-10 adjustment sets the percentage of
rated gpm/lpm to use. Settings below 2 are not
recommended.
Preset Rate:
Pump and application rate are set by a combination
of ground drive sprockets (not shown) and dial
setting. See page 92 for preset rate setting.
Variable Rate:
The pump is typically operated at dial setting 10,
using whichever ground drive sprocket provides
higher-than-needed gpm/lpm. Application rate is
controlled by valve , which diverts excess flow
back to the nurse tank.
L33. Pump Adjustment Tool
(ground drive implements only)
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.

L35. Pressure Gauge
(ground drive implements only)
This 0-to-100 psi gauge reports the pressure in the
manifold, which is typically 15-40 psi during
application. The pressure should be above zero
only when fertilizer is flowing. The back-pressure at
the nozzle orifices falls quickly when the pump
stops.
Check the pressure periodically during application.
If it rises to over 65 psi, the relief valve may be
activating. See also pressure sensor .
L36. Relief Valve
(ground drive implements only)
Adjust this valve to activate at 65 psi (page 91).
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.
L37. Dump Line
(ground drive implements only)
If the relief valve operates, material is jettisoned
at this tube. If you observe dumping, check the
pressure and review the orifice plate
configuration.
L38. Hydraulic Drive Pump (Option)
Hydraulic Drive Option: The Ace
FMC-150F-HYD-206 has a capacity of up to
150 gallons/minute (560 liters/minute). See the Ace
Pump Instruction manual (HYD-MAN) for
maintenance.
L39. Air Bleed Line
(hydraulic drive pump implements only)
This line to the tank enabled pump priming by
bleeding off air. If using an off-applicator tank, a
user-provisioned bleed line or bleed valve must be
provided for pump priming.
L40. Flow Control Valve
(variable rate only)
Under the control of the console (not shown) this
valve is being constantly adjusted to divert back to
the tank, any material not required at the current
application rate (as reported by the flow meter ).
L41. Flow Meter
(variable rate only)
This sensor reports the actual material rate entering
the variable rate manifold. As it detects variations
from your desired rate, it signals the console to
adjust the control valve .
L42. Passive Manifold
(used only with preset rate implements)
This plumbing cross splits the flow into three
sections. Equal flow is assured by the orifice
plates .
L43. Section Valves
(variable rate only)
There are three On/Off solenoid valves (1, 2 & 3).
These open and close under the control of BOOM
switches on the Raven SCS 450 console, or as
commanded by a controller with section capability.
L44. Bypass Valve
(variable rate only)
This 4th manifold On/Off valve is normally closed.
If the controller commands all of the section
valves to close, it also commands the bypass
valve to open. The flow control valve cannot
respond as quickly as On/Off valves, so the bypass
valve controls pressure spikes by diverting some
flow back to the tank.
L45. Pressure Sensor
(variable rate only)
The optional Raven SCS 450 console displays the
manifold pressure during operation. This is
measuring essentially the same pressure as the
mechanical pressure gauge .
L46. Boom
There is one boom assembly per implement
section. Booms may be different lengths at center
and on wings. The assembly feed may be via a tee
or into one end of the boom.
Preset rate implements are operated as a single
boom. Variable rate implements are operated as a
three-section boom.
L47. End Cap
A boom has at least one end cap. A tee-supplied
boom has two caps. These caps are removed for
clean-out (see page 103).
L48. Boom Clamp
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 103) is necessary to prevent
over-winter freezing of residual material.
Booms typically have more boom clamps than
applicator rows (the same boom assembly is used
on multiple implement models). Active rows have
nozzle bodies . Inactive stations have shutoff
caps .

L49. Shutoff Cap
Unused boom clamp stations are capped. Use a
gasket (with or without plate) under a cap.
L50. Gasket
This flat O-ring seals the nozzle 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.
L51. Orifice Plate
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 88 for plate selection and installation.
L52. Nozzle Body
This fitting adapts the boom clamp to tubing, and
may be positioned for forward or rear tubing
direction.
L53. VeriFlow Nozzle (Option)
This accessory replaces components , and
with a spring-regulated valve nozzle that
requires no adjustment (or orifice plate changes)
over a wide range of flow rates.
L54. Drop Tubing
This tubing carries the material to the row.
L55. Applicator Tube
This metal tubing delivers the material to the trench
opened by the coulters. The exit port is protected
behind arm structure. The arm may be adjusted for
release depth relative to coulter depth (page 66).
L56. Tine Nozzle
Coulter Option: This stainless steel fitting (part
number 828-046C) delivers the material to the
trench opened by the coulters. It has an 0.040 in.
orifice port. Alternate sizes are available (see
page 119).

Preparation and Setup
This section helps you prepare your tractor and NP30L
or NP40L 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.
Initial Setup
See manual 407-313Q for pre-delivery items (normally
completed by dealer), and first-time/infrequent setup
tasks, including:
• Adjust field lift partial fold on 2-Point (page 140).
• Install optional variable rate console in tractor
(page 142).
• 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 105).
• 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 109.
Check that all safety decals and reflectors are
correctly located and legible. Replace if damaged.

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.
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.
Refer to Figure 13
To distinguish hoses on the same hydraulic circuit, refer
to the cylinder symbols on the hose handles
• The hose with an extended-cylinder symbol feeds a
cylinder base end, or the return side of a hydraulic
motor.
• The hose with a retracted-cylinder symbol feeds a
cylinder rod end, or the pressure side of a hydraulic
motor.
On a 2-point

implement, connect either hose to either
side of the remote. Use a regular remote and not a
dedicated tractor 3-point remote

a. Older implements do not have handles. The cylinder symbols are instead on a hose label clamped near the QD connectors.
b. The 2-Point implement has a merged hydraulic circuit in which different cylinders are extending and retracting at the same time, and thus
cannot meaningfully use the hose label. Determine by testing which lever direction lifts/folds and lowers/unfolds.
c. Some tractors provide a special remote pair at the 3-point hitch arms. On some tractor models, this circuit has specific flow and/or pres-
sure-sensing behavior intended for certain implements (other than Nutri-Pro
circuit.

Hydraulic Pump Hookup (Option)
The hydraulic pump used has a 7 gpm (23 liters/min.)
motor. If the tractor used does not have the capabilities
to adjust the remotes down to this flow, then a Hydraulic
Flow Divider Kit must be installed so that flow can be
controlled to prevent operating the pump at excessive
speeds. See a Great Plains dealer for more information.
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 14
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 61 for setting flow rate.

stand was already stored at an earlier step).
Refer to Figure 16 (which depicts the same style
stand on an NP4000 applicator)
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 44.
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.
Raise Parking Stands (older applicators)
This applies to 2-point (lift assist) hitching, and 3-point
hitching (but not pull-type hitching, as the tongue parking
stand was already stored at an earlier step).
Refer to Figure 16
1. Use tractor 3-point hitch (and if so equipped, the
lift-assist circuit) to slightly raise the implement. See
“Raising/Lowering Applicator” on page 44.
2. Remove the pivot pin at each stand. To prevent
the leg from reaching (and possibly passing) full
vertical, insert the pin in the rear storage hole .
Crushing Hazard:
Do not stand in front of the leg while raising it. The stand leg is
is heavy. If you lose control of it, it can fall forward and may
cause injury.
3. Swing the stand forward, up and then back.
4. Re-insert the pivot pin in either of the two upper
holes, and the leg tube, to secure the leg at vertical.
Note: The rear hole holds the stand at full vertical.
5. If the leg cannot be swung up due to interference
with a tractor component (such as a tire), see
“Parking Stand Clearance” on page 143.

Leveling Implement
During initial setup and periodically throughout the
season, check that the implement runs level. When
planting, 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 “Application Height Adjustment”
on page 66.
To check level, lower the implement into the ground in
representative conditions.
3-Point Leveling
Refer to Figure 17
Leveling is controlled entirely by the tractor hitch.
2-Point 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 18
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.

SCS 450: SPEED CAL
A speed sensor connection to the Raven SCS 450 is
required. Perform a calibration per the manuals for the
sensor and the SCS 450.
A speed sensor input allows the SCS 450 to determine
and control application rates at arbitrary field speeds.
Note: The Raven flow control bundles offered by Great
Plains do not include a speed sensor, nor the cable
necessary to connect a Raven-compatible sensor
or radar to the SCS 450 See page 114 for an
available radar kit. See page 123 for harness
cables available from Great Plains or Raven.
SCS 450: METER CAL
This is the pulse-vs.-rate calibration number for the flow
meter ( in system diagrams in this manual).
Obtain this number from the tag affixed to the meter.
Enter it into the SCS 450 and record on the Calibration
Card.
SCS 450: VALVE CAL
This is the response time calibration number for the
control valve ( in system diagrams in this manual).
Obtain this number from the tag affixed to the valve.
Enter it into the SCS 450 and record on the Calibration
Card.
SCS 450: PRESSURE CAL
This DATA MENU sequence sets zero for the pressure
transducer ( in system diagrams in this manual).
Perform this operation only when lines are at zero
pressure.
SCS 450: RATE 1 CAL
This is your primary desired application rate, typically in
gallons per acre.
SCS 450: RATE 2 CAL
This is your secondary desired application rate, typically
in gallons per acre. If you have no alternate rate
preferred, set this to RATE 1 CAL, so that the control
valve won’t slew if you need to switch to MAN mode.

Wing Lock Channels
Refer to Figure 26
These lock channels are only present on 2012- NP40A,
NP30A, NP3000 2-point with lift assist and 3-point
models. They enable a partial “gull wing” fold during field
lift. On 2013+ 5-section models, this function is
controlled by solenoid valves.
See page 51 for operation.
Wing Lock Pins
These pins are present only on NP40A models with
5-section wings (inner and outer wings).
Refer to Figure 29
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 “Unfolding and Folding 2013+ 5-Section 2-Point”

Outer Wing Fold Latches
These pins are present only on NP40A models with
5-section wings (inner and outer wings).
Refer to Figure 30
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
These valves are present only on 2013+ 2-Point NP40A
models. They normally require no operator attention.
See “2013+ NP40A 2-Point Fold/Lift Circuit” on

(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.

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.
2013+ NP40A 2-Point Fold/Lift Circuit
On 2-point NP40L 5-section applicators made in 2013 or
later, 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 31 (depicting the switch in PARK)
This switch is mounted in the tractor cab (page 139), and
connected to the applicator at the hitch. It controls
several solenoid valves on the applicator. It has three
toggle positions and two indicator lamps.
Note: The switch is powered by the tractor. An illuminated
lamp indicates power sent to the harness. The
harness must be connected at the hitch for the
function to be effected.
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.

Equipment Damage Risk:
Do not back up when lowered. Always raise the applicator for
any reverse/backing. Backing when lowered will plug tines,
and can damage delivery tubing.
Note: Lowering while stationary may result in lift-assist
or front caster wheels being lifted off the ground.
The applicator may not be at operating depth until
it is pulled forward in field conditions.

Raising/Lowering Applicator
When raising in the field with a hydraulic drive pump, first
turn off material flow. See page 61.
Lift/lower procedures depend on applicator model, year
and hitch type:
• Pull-type applicators use six cylinders for lift/lower.
The lift circuit is separate from the fold circuit.
See “Raise/Lower Pull-Type” on page 45.
• 3-point applicators rely solely on the tractor hitch.
Separate partial activation of the fold circuit is
necessary to avoid wing droop in lift.
See “Raise/Lower 3-Point” on page 46.
• 2-point applicators rely on the tractor hitch at
applicator front, and a lift-assist cylinder circuit at
rear. Lift and fold share a remote circuit.
3-section and 2012- 5-section: Wing lock channels
must be configured to arrest fold during lift. See
“Raise/Lower 2012- & 3-Section 2-Point” on
page 47.
2013+ 5-section: Solenoid valves provide partial “gull
wing” fold during lift. See “Raise/Lower 2013+
5-Section 2-Point” on page 49.
Operate the tractor hitch in “position” or “depth” control
mode, regardless of applicator hitch type.
The lift circuits are re-phasing master-slave on pull-type
and 3-section or 2012- 2-point. See “Re-Phasing Pull-
Type Lift System” on page 45.
The applicator may be raised and lowered while folded.
Weight-Transfer Shut-Off Valve
This applies to:
all 3-section,
all pull-type,
all-3-point, and
all 2012- NP40A (3 and 5-section).
The 2013+ 5-section 2-point weight transfer has no
interaction with raise/lower.
Refer to Figure 32 (depicting the valve closed on an
NP3000, which has the same weight transfer
hydraulic system)
Model 2011 and later (and updated model 2010)
applicators have a shut-off valve in the weight transfer
system. This “weight-transfer shut-off valve“, when
closed, bypasses the pressure reducing valve, and
allows fold cylinders to operate at full speed. The weighttransfer shut-off valve must be open for the weight
transfer system to operate in the field.

NP30L or NP40L Table of Contents Index Operating Instructions 45
Raise/Lower Pull-Type
Five of the six lift cylinders are slaved to the left front
caster wheel cylinder, which has a hydraulic down stop.
Equipment Damage Risk:
Do not fold while in ground. Fold only when fully raised. When
lowered, the wing coulters and tines near the wing pivot may
be damaged by ground dragging.
Raising Pull-Type
Material Loss Risk:
When raising in the field with a hydraulic drive pump, first
turn off material flow. See page 61.
To raise the applicator, extend the cylinders (normally
with an Extend operation of the tractor remote).
The applicator raises fully at end of stroke, regardless of
depth setting. Holding the circuit at raised for a few
seconds re-phases the cylinders.
If raising for highway transport, parking or storage,
engage center section lift cylinder lock channels
(page 38).
If raising for maintenance, swing out hydraulic depth stop
and engage all lift cylinder lock channels (page 38).
Lowering Pull-Type
If lock channels are engaged on any lift cylinders, raise
the applicator and disengage the channels (page 38).
Re-engage the depth stop as needed.
To lower the applicator, retract the lift cylinders (normally
with a Retract operation of the tractor remote).
The applicator lowers to the depth set at the hydraulic
depth stop at the left front caster wheel. See “Hydraulic
Depth Stop Adjustment” on page 70 for details on
height adjustment.
Re-Phasing Pull-Type Lift System
In typical use during a single application operation, it is
normal for the lift cylinders to get out of phase, resulting
in uneven raising and lowering of the fertilizer applicator.
Every 8 to 10 passes, re-phase the cylinders with this
procedure:
1. Raise the applicator completely, and hold the
hydraulic lever or switch in Extend for several
seconds after the applicator reaches full elevation.
2. When all cylinders are fully extended, momentarily
reverse (Retract) the control to lower the
applicator 1/2 inch (12 mm).
3. Set circuit to Neutral to hold for level check.
If re-phasing does not bring the applicator into level,
other possibilities include:
• tire pressures too high or too low (page 122),
• worn tires,
• pull-type tongue height incorrect (page 33),
• 2-point tractor hitch height and level incorrect,
• 2-point gauge wheel height incorrect (page 68),
• 2-point lift-assist height spacers incorrect or not
installed (page 34), and;
• front caster wheel / lift-assist eyebolts (page 107)
• significant amounts of air in the hydraulic system,
indicating a need to perform a hydraulic bleed.
Gradual Crushing Hazard:
Do not rely on hydraulic pressure alone to keep the fertilizer
applicator raised. Use transport/lift locks (page 38) when
working around a raised fertilizer applicator. The bypass
orifices in the re-phasing system cause it to slowly lower.
2018-10-10 Table of Contents Index 407-313M
Page 50
NP30L or NP40L Table of Contents Index Operating Instructions 46
First Pass Lowering:
• If the wings are drooped, retract the fold circuit
(page 51) to bring the wings into contact with the
wing locks, or to wings level. Set fold circuit to
Neutral until lowered to ground.
Raise/Lower 3-Point
The height/depth of the center section of a 3-point
fertilizer applicator is controlled entirely by the tractor
hitch.
The height of the wings is controlled by manually-set
wing gauge wheels. Operator action during lift and lower
is needed to control wing droop.
Raising 3-Point (Field Lift, Unfolded)
These instructions presume that the intention is to lift
without folding, that the applicator is unfolded, and that
the wing fold locks auto-engaged at the last unfold, and
have not been reset. If the intention is to lift and fold, see
“Folding 3-Point” on page 51.
Material Loss Risk:
When raising in the field with a hydraulic drive pump, first
turn off material flow. See page 61.
1. Fold the wings up. The wing locks arrest the fold just
above wings-level. Set circuit to Neutral.
2. Lift the center section with the 3-point.
Raising 3-Point (Transport/Service Lift, Folded)
If the wings are already folded, and are being left that
way, you may raise (and lower) the 3-point hitch without
touching the fold circuit.
Lowering 3-Point (Field Lower, Unfolded)
See sidebar for first pass.
1. Lower the 3-point hitch to field setting.
2. Set hitch to Depth Control mode.
3. Set fold circuit to Float.
If you are already in forward motion, the knives or tines
will pull the applicator to application depth. Otherwise,
the applicator will rest on the knives or tines until pulled
forward.
Lowering 3-Point (Parking/Service, Folded)
Deploy parking stands (page 31) if parking, storage or
service is the intention.
If the wings are already folded, and are being left that
way, you may lower (and raise) the 3-point hitch without
touching the fold circuit.
2018-10-10 Table of Contents Index 407-313M

NP30L or NP40L Table of Contents Index Operating Instructions 47
Gradual Crushing Hazard:
Do not rely on hydraulic pressure alone to keep the applicator
raised. Use parking stands (page 31) and transport/lift locks
(page 39) when working around a raised applicator. The
tractor hitch may settle. The bypass orifices in the applicator
lift-assist re-phasing system cause it to slowly lower.

Raise/Lower 2012- & 3-Section 2-Point
These instructions apply to 3-section applicators and
2012- 5-section applicator. For 2013+ 5-section
applicators, see page 49.
Refer to Figure 33
The front height of the applicator center section is
controlled by the lower two tractor 3-point arms (not
visible in figure).
The rear height of the applicator is controlled by two
lift-assist cylinders . Spacers are provided to limit the
“lowered” position (page 34).
Raising 2012- & 3-Section 2-Point (Field, Unfolded)
These instructions presume that the intention is to lift
without folding, that the applicator is unfolded, and that
the wing fold locks auto-engaged at the last unfold, and
have not been reset. If the intention is to lift and fold, see
“Unfolding and Folding 3-Section & 2012- 5-Section
2-Point” on page 52.
When raising in the field, the wings tend to droop. Use
the fold circuit to counter this.
1. Retract the fold cylinder circuit until the wing locks
stop motion, or the outside row knives or tines just
start to lift out of the ground. Set the circuit to
Neutral.
2. Raise the tractor hitch. This raises the knives or tines
with a slight forward motion, preventing plugging of
the ammonia tube outlets.
3. Extend the lift-assist cylinders (normally with an
Extend operation of the tractor remote).
Note: Holding the lift-assist circuit at raised for a few
seconds re-phases the cylinders.
4. When fully raised, set all remotes to Neutral.
Raising 2012- & 3-Section 2-Point (When Folded)
Refer to Figure 33 (depicting an NP3000, which has
the same weight transfer hydraulic system)
If the applicator is already folded:
1. Close the weight-transfer shut-off valve .
2. Raise it with the 2-point and lift-assist circuits in any
order.
3. Hold at raised with Neutral circuits.
4. Install rear lift-assist lock channels (page 38).
5. Deploy parking stands (page 31).
If the applicator is unfolded, and the intention is to lift and
fold, see “Unfolding and Folding 3-Section & 2012-
5-Section 2-Point” on page 52.
2018-10-10 Table of Contents Index 407-313M
Page 52
NP30L or NP40L Table of Contents Index Operating Instructions 48
First Pass Lowering:
• If lock channels are engaged on the rear lift-assist
cylinders, raise the applicator, disengage the
channels (page 39), and insert the desired number
of spacers (page 32).
• If the wings are drooped, retract the fold circuit to
bring the wings into contact with the wing locks, or
to wings level. Set fold circuit to Neutral until
lowered to ground.
Equipment and Pavement Damage Risk:
Fully fold before lowering onto parking stands. Parking stands
support only the center section. If unfolded, wings may be
drooped, or will droop. Knives or tines will strike the ground,
immediately or eventually.
Lowering 2012- & 3-Section 2-Point (Field, Unfolded)
See sidebar for considerations on a first pass.
1. Close the weight-transfer shut-off valve (page 47).
2. To lower the applicator, lower the tractor hitch and
retract the lift-assist cylinders (normally with a
Retract operation of the tractor remote).
3. The front of the applicator lowers until the hitch
movement is stopped by your control, or by any
depth stop set on that control.
4. The rear of the applicator lowers until the cylinders
are stopped by the installed spacers (page 34), or
until fully retracted if there are no spacers. If the
knives or tines are not in the ground, the lift-assist
wheels come off the ground until you pull forward
into the field.
5. The unfolded wings lower to the height set by the
wing gauge wheels (page 68) or onto the knives or
tines.
6. Set the 2-Point to Depth Control.
Set lift and fold circuits to Float.
Lower 2012-& 3-Section 2-Point (Service/Parking,
Folded)
This topic presumes that the intention is to lower a folded
applicator without unfolding. If the intention is to both
lower and unfold, see “Unfolding 3-Section & 2012- 5-
Section 2-Point” on page 52.
1. Close the weight-transfer shut-off valve (page 47).
2. Raise the applicator. Set circuits to Neutral.
3. Remove spacers (page 34) and install lift-assist lock
channels. Deploy parking stands (page 31) as
desired.
4. Lower rear of applicator with lift/fold circuit. Stop as
soon as rear cylinders are fully retracted or on
spacers/locks.
5. Lower front of applicator with 2-point hitch.
6. Set circuits to Float.

unfolded, already raised, but on lift-assist locks at rear,
on extended gauge wheels at wing tips, and on parking
stands at hitch.
1. Verify that lock channels are installed on the
lift-assist cylinders (page 39), that wing lock pins are
not in the locking holes (page 41) and that the
hydraulic harness is connected at the hitch
(page 28).
2. Raise the tractor 3-point hitch enough to lift gauge
wheels, coulters, and the parking stand bases off the
ground. Set the hitch circuit to Neutral.
Refer to Figure 35
(depicting an NP4000 with similar fold system)
3. Set the FOLD / FIELD switch to FIELD. This arrests
fold at field lift.
4. Retract the fold/lift circuit until lift-assist and wing fold
operations each their stops. Set fold/lift circuit to
Neutral. Shut off the tractor engine, leaving the

Unfolding and Folding
All Nutri-Pro® applicators have identical fold cylinders
(with weight transfer capability), but they differ in locks
and operational steps:
• Pull-Type applicators have a dedicated fold system
with no wing locks. See “Unfolding and Folding
Pull-Type” on page 50.
• 3-Point applicators have wing locks requiring reset
prior to fold. See “Unfolding and Folding 3-Point”
on page 51.
• 2-Point applicators have a lift-assist that usually
requires reconfiguring just prior to unfold and fold.
Additional steps vary with configurations:
On 3-section, and 2012- 5-section, wing locks
require reset prior to fold. See “Unfolding and
Folding 3-Section & 2012- 5-Section 2-Point” on
page 52.
2013+ 5-section applicator require a switch setting
change. See “Unfolding and Folding 2013+
5-Section 2-Point” on page 54

Unfolding 2013+ 5-section 2-Point (At Field)
These instructions presume the applicator has just
completed transport, is raised, and transport locks are
installed. It is being unfolded for field use.
1. Remove the wing lock pins (page 41).
Refer to Figure 39 and Figure 40
2. Set the FOLD / FIELD switch to
FOLD / UNFOLD.
3. Extend the fold/lift circuit to unfold the wings
4. Retract the fold/lift circuit slightly to raise the
lift-assist off the lock channels.
5. Set all circuits to Neutral. Shut off the tractor.
6. Remove the lift-assist lock channels (page 39).
Install the spacers (page 34).
7. If wing gauge wheels were extended, crank them to
field height (page 68).
8. Lower the hitch to field height.
Notes about normal unfold:
• Inner wings unfold first. The outer wings are
constrained by the wing latches (page 42).
• Outer wings unfold last. The wing latches release just
before the inner wings are level.
• Wings do not unfold to below wings-level.
Machine Damage Risk:
Set the switch to UNFOLD. If set to PARK or FIELD, the
wings may unfold to below level and drag inward on the
ground.

Folding 2013+ 5-Section 2-Point
These instructions presume that the applicator is
unfolded and lowered.
1. Verify that the wing lock pins (page 41) are not in the
wing rest cradles. Typically they are in storage tubes.
Refer to Figure 41
2. Set the Fold switch to
FOLD / UNFOLD.
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 42
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 34). Install lift-assist cylinder
locks (page 39).
7. Insert wing lock pins (page 41).
8. Extend fold/lift to lower lift-assist cylinders onto lock
channels. Set fold/lift circuit to Float. Shut off tractor.
For parking/storage/service, lower the applicator onto
parking stands.

Transport
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.
Loss of Control Hazard (2P, Pull-Type):
Never tow a pull-type or 2-point implement that weighs more
than 150% of the tractor (transport tractor must weigh at least
67% of implement). Ensure that the towing vehicle is adequate
for the task. Using an inadequate tow vehicle is extremely
unsafe, and can result in loss of control, serious injury and
death.
Tractor weight matters. For field configuration (after
transport), tractor must weigh at least 150% of the implement
plus the loaded nurse tank. This weight is substantially higher
than the required transport weight.
Loss of Control Hazard (2P, 3P):
Never transport a 2-point or 3-point implement unless the
tractor is properly ballasted to provide adequate weight on the
steering wheels. A heavy 2-point or 3-point implement can
dangerously reduce steering control. A normal turn could
result in an accident and serious injury or death. Check your
tractor manual for ballasting requirements.
Tractor weight matters. For field configuration (after
transport), tractor must weigh at least 150% of the implement
plus the loaded nurse tank. This weight is substantially higher
than the required transport weight.
Braking and Loss of Control Hazard:
Do not exceed 20 mph (32 kph).
2018-10-10 Table of Contents Index 407-313M
Page 61
NP30L or NP40L Table of Contents Index Operating Instructions 57
Transport Steps
Know your implement weight. See page 121 for a list of
approximate weight of various configurations.
If tractor capabilities are marginal, check actual weight of
implement at a scale.
Pull-Type:
1. Check that implement is securely hitched to a
sufficient tractor (page 27).
2. Always use a locking-style hitch pin sized to match
holes in hitch and draw-bar (minimum
1-inch-diameter, heat-treated pin).
3. Attach safety chain to tractor with enough slack to
permit turning (page 26).
4. Verify correct operation of lights.
5. Raise fertilizer applicator (page 45).
6. Install center and lift-assist cylinder locks (page 38).
7. Fold applicator if unfolded (page 50).
8. Check that tires are properly inflated (page 122).
9. Plan the route. Avoid steep hills.
10. Always have lights on for highway operation.
11. Do not exceed 32 kph (20 mph). Comply with all
national, regional and local laws when traveling on
public roads.
12. Remember that the implement may be wider than
the tractor. Allow safe clearance.
13. Transport slowly over uneven or rough terrain.
2-Point and 3-Point:
1. Check that fertilizer applicator is securely hitched to
a sufficient tractor (page 26)
2. Verify correct operation of lights.
3. Raise fertilizer applicator (page 47).
4. Install lift cylinder locks (2-point, page 38).
5. Fold applicator if unfolded (page 50).
6. Plan the route. Avoid steep hills.
7. Always have lights on for highway operation.
8. Do not exceed 32 kph (20 mph). Comply with all
national, regional and local laws when traveling on
public roads.
9. Remember that the fertilizer applicator may be wider
than the tractor. Allow safe clearance.
10. Transport slowly over uneven or rough terrain.
Final Implement Setup
Prior to hitching nurse tank, make and check final
implement adjustments. This could include:
• Application depth, page 66.
• Application Rate, page 80.
• Row cleaner adjustments, page 93.
• Make a dry run to check implement functions,
running depth and sealing.
For nurse cart hitching, the implement may be raised or
lowered, folded or unfolded. However, raised and folded
hastens departure if any nurse tank problems are
discovered before cart hitching.
Fill Nurse Tank
Consult the nurse tank documentation for specific steps.
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.
If the fertilizer solution has any tendency to settle,
sediment, gel, coagulate, precipitate or stratify, load
material immediately prior to application.

Hitching Nurse Tank
Hitch a nurse tank to the implement only at the field, and
not prior to transport.
Mechanical Cart Hitching
1. Spot the implement to avoid reverse moves after cart
hitching.
Refer to Figure 44 (older high-clearance hitch shown)
2. Bring the implement rear hitch tongue and nurse
tank cart tongue into close proximity (a few inches).
3. Push down on the red tongue release handle . This
frees the implement rear hitch tongue to extend
7 inches (17.8 cm) to the rear, and 9 inches (23 cm)
to either side, to assist with cart tongue alignment.
4. Align the cart clevis hitch with the implement pull bar.
Insert and secure the 1 inch hitch pin.
5. Securely attach the cart’s safety chain(s) to the hitch
chain anchor(s) .
6. Optionally re-seat the implement rear hitch tongue,
at this time, by using the tractor to move the
implement backward several inches, until the latch
on the hitch re-engages.
Making Tank Connections
Connections are different for preset rate implements and
variable rate implements.
Tank Connections: Preset Rate
Refer to Figure 6 on page 19
1. Close shut off valves on all hoses of both tank
and implement .
2. Route tank supply hose to implement inlet .
Allow ample slack for tight field turns and uneven
ground. Do not leave so much slack that the hose
can reach the ground.
3. Remove plug from implement inlet, and any cap on
tank supply hose.
4. Inspect and clean connector fittings.
5. Mate connectors of tank and implement supply
hoses. Fold cam levers forward to lock. Leave valves
closed.
6. If the tank has additional hoses, secure them at the
tank.
Tank Connections: Variable Rate
Refer to Figure 7 on page 20
1. Close all shut off valves on all hoses of
tank ( , , , possibly more) and
implement .
2. Route tank supply hose , return hose and
bypass return hose to implement inlet . Allow
ample slack for tight field turns and uneven ground.
Do not leave so much slack that any hose can reach
the ground.
3. Remove any plug from implement supply inlet ,
and any cap on tank supply hose .
4. Inspect and clean connector fittings.
5. Mate implement inlet and tank supply connectors.
Fold cam levers forward to lock. Leave valves closed.
6. Repeat step 3 through step 5 for the pump return
line ( and ), and then the bypass return

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.
Equipment Damage/Material Misapplication Risks:
Do not run pump dry. With all drive chains in place, the pump
always runs when the fertilizer applicator is lowered and in
motion. Air rapidly damages a pump. Keep fluid in pump at all
times. Disconnect a chain 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).
Sharp Object Hazard:
Exercise caution when near and handling the ground drive
wheel. Wear gloves. The tines may be sharp.

Fertilizer Operation
The liquid fertilizer 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.
Setup and operation are different for:
• Ground Drive Preset Rate
• Ground Drive Variable Rate
• Hydraulic Drive Pump (Variable Rate)
Ground Drive Operations
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 .
These steps presume that fertilizer has been loaded into
the supplying tank, and the tank is configured and ready
for use, with shut-off valves closed on hoses to
implement.
1. Check ground drive sprocket setup (page 91).
2. Set rate on pump adjuster dial (10 for optional
variable rate).
3. Set rate on console (optional variable rate only).
Refer to Figure 6 on page 19 or Figure 7 on page 20
4. If relief valve has not been previously adjusted,
perform initial setting per page 91.
Prime the Ground Drive System.
5. On suitable ground, raise the fertilizer applicator.
6. With the optional variable rate system, use the
SELF TEST feature of the SCS 450 console to
simulate a field speed.
7. Wearing gloves, manually rotate the ground drive
wheel until material appears at the applicator tubes.
Ground Drive Field Operations
8. Begin field operations. Monitor the fertilizer pressure
gauge (or PSI display on optional console).
9. Mind the fertilizer tank levels while planting, both to:
a. confirm expected consumption rate, and;
b. avoid running the pump dry.
10. If residual fertilizer is not recovered at end of
planting, apply it to the last field planted.
11. Clean out fertilizer system per page 103.
Ground Drive Pauses and Turns
When the implement is stopped, or lifted, the pump
stops. The boom is still pressurized, but this bleeds down
to 8 psi very quickly (seconds), at which point the nozzle
clamp check valves close off flow to the rows.
If the implement has the optional variable rate system, it
is not necessary to turn off the MASTER switch at stops
and turns. However, do use the BOOM switches as
desired for point row applications.

Hydraulic Drive Operations
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).
Hydraulic Drive Start-Up
Prior to first use, determine the hydraulic remote circuit
flow rate setting per the procedure on page 94.
12. Set console MASTER switch OFF.
13. Set console POWER switch ON.
14. Select FLOW CONTROL RATE1 or RATE2 as
desired, and verify rate setting.
15. Set console BOOMS
16. Set the flow rate for the hydraulic remote circuit as
established by the procedure on page 94.
17. 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.
18. Set the MASTER switch ON. Check for material flow
at the tines. Prime second hydraulic pump as
required.
19. Begin field operations. Monitor the fertilizer pressure
gauge (or PSI display on optional console).
Hydraulic Drive Field Operations
20. Monitor the fertilizer manifold pressure (gauge or PSI
display on optional console).
21. Mind the fertilizer tank levels while planting, both to:
a. confirm expected consumption rate, and;
b. avoid running the pump dry.
22. If residual fertilizer is not recovered at end of
planting, apply it to the last field planted.
23. Clean out fertilizer system per page 103.
Hydraulic Drive Pauses and Turns
With 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.
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.

switch 1 ON.
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.

Monitor Operation (Option)
Refer to Figure 45
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.
Piston Pump Damage Risk:
When configuring the pump for high rates, check the chart,
slide chart or CDS-John Blue web calculator to determine the
maximum field speed that stays at or below the pump’s
maximum rated rpm.
Starting Application with Console
1. Enter the tractor cab.
Refer to Figure 45
2. At the console, set the POWER switch ON.
3. Set the MASTER switch to ON.
4. Set the BOOMS 1 or BOOMS 1,2&3 switch
ON
all others don’t-care (suggest OFF).
5. Select the desired RATE preset.
6. For hydraulic drive, engage the remote for the
hydraulic drive pump. Advance lever to preset for
+35% of desired rate.
7. Lower implement to operating depth (if not already
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 a ground drive pump system (preset or variable
rate).
Ending Application
1. Ground Drive: If possible, plan final passes so that
they occur prior to tank run-out. This keeps the pump
wet. If you do exhaust the material, refill with water.
2. At completion of application, apply almost all of the
remaining fertilizer on the last field. Refill the tank
with clean water.
3. Set application rate to maximum to shorten the
remaining steps:
• Ground drive: exchange the ground drive driving
sprocket to obtain High Range (page 91).
• Ground drive: set the pump dial to 10 (page 92).
• Variable rate (either drive): set the console for
maximum rate.
4. Apply water to the final field to flush the system.
5. Close shut-off valves on both sides of all hose
connections.
6. Disconnect all cam-lock couplers from the tank to the
implement.
7. For a trailing nurse tank cart:
8. Disconnect the safety chains.
9. Remove the hitch pin. Move the trailer hitch off the
implement’s draw bar.

page 61.
2. Choose an implement parking location with level firm
ground. Do not unhitch on a steep slope.
3. Fully raise implement (page 44).
4. Fold applicator (page 50).
5. Depending on hitch type:
Engage center section and lift-assist transport locks
(page 38), and/or
swing down parking stands (page 31) and/or
install jack stand on tongue (page 27).
6. Lower fertilizer applicator onto locks/stands. On
pull-type, use parking jack to neutralize tongue
weight at tractor hitch.
7. Set hydraulic circuits to Float.
8. Shut off tractor.
9. Disconnect hydraulic lines. Secure them so that they
do not touch the ground.
10. Disconnect electrical cables, capping where
provisioned.
11. Disconnect any safety chain. Unhitch. Restart tractor

Application Height Adjustment
Fertilizer release height is normally at or just above the
ground, and is controlled by three adjustments:
Refer to Figure 46
1. Tool bar height:
This affects coulter depth. The procedure for setting
tool bar height varies with hitch type:
See page 68
2. Fertilizer arm height (page 67):
This affects arm height relative to the coulter.
This adjustment is primarily to compensate for blade
wear.
3. Coulter height (page 67):
This affects coulter height relative to the tool bar, and
is normally not adjusted.
Factory settings:
25 in. (63.5 cm) above ground at 4 in. coulter depth
7.5 in. (19.1 cm) coulter shank distance
1 in. (2.5 cm) release height
Vantage I Coulter Force
Coulter springs are set to 400 pounds (181 kg). In
normal operation at target running depth, the spring is at
full extension 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.
To adjust the coulter spring:
Refer to Figure 46
1. Raise the applicator and install transport locks. See
“Raising/Lowering Applicator” on page 44.
2. Determine the new spring length desired.
Setting all springs above 400 pounds might require
the optional weight kit with some lighter triple-coulter
configurations.
Note: If all springs are continuously in compression, the
coulters can lift the wing frames off the ground (at
the gauge wheels), resulting in uneven coulter
depth and/or uneven seed depth. If already
operating at maximum down-pressure, reduce
coulter depth.

3. Measure the current length of the spring(s) to be
changed. If already as short as 9
as long as 10

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

Vantage I Coulter Height and Castering
Coulter height is the main control for application height.
Coulters may need to be lowered for rows in tracks.
Coulters applicator-wide need adjustment as blades
wear.
Coulters may also be set for rigid row alignment, or
limited castering.
Refer to Figure 47 and Figure 48
1. The factory setting for coulter height is a distance
of 7.5 inches (19.1 cm) from frame bottom to top of
coulter mount casting.
At a tool bar height of 25 inches (63.5 cm) above
ground, this is a blade depth of
4 inches (10.2 cm).
2. For fields where frequent sharp turns are
unavoidable, you can reduce coulter plowing by
allowing the coulters to caster at the pivot casting.
Loosen the jam nuts at . Loosen the set screws
just enough to allow the casting to swivel. Re-tighten
the jam nuts. Do not remove the center stop screw.
3. As blades wear, keep the release height constant
by raising the applicator weldment on the coulter
arm. Loosen the bolts . Slide the weldment up.
Tighten the bolts.
If the application height is still too low after this
adjustment, the coulter blades may be worn and in
need of replacement.
Refer to the Vantage I manual (204-376M) for further
coulter adjustments.
Vantage I Blade Wear
Blade wear is normal and the rate of wear varies with
field conditions and operating depth. Consider replacing
the blade when the initial diameter has been reduced by
1to2 inches.
Note: Although a nominal 20 inches in diameter, blades
are lightly larger and vary slightly with blade style.

Note: Turn crank clockwise to raise implement (lower
wheel), and counterclockwise to lower implement
(raise wheel).
Note: At maximum height, the coulters are off the
ground. This configuration is useful for unfolded
parking, storage and service.
Make a record of the setting needed for coulter
depth prior to setting for maximum.

Make sure the implement is level and the lift system bled and
re-phased before adjusting the tool bar height. If the center
section does not consistently stop at the set height, or the
wings do not run at the same height as the center, the lift

Hydraulic Depth Stop Adjustment
This applies to pull-type applicators only. See page 68 for
2-point and page 69 for 3-point.
The lift system includes an adjustable stop valve, on the
left front caster wheel, to fix the height of the opener
frame when the implement is lowered.
Note: The change in coulter depth is not linear and can be
greater than the change in down-stop adjustment.
Make adjustments in small amounts.
Refer to Figure 51
1. Move to smooth level ground with soil as similar as
possible to field conditions.
2. Unfold the implement (page 50).
3. Lower the implement until the coulters just touch the
ground. Hold that height by setting the lift circuit to
Neutral.

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 components 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.

Description of system
Refer to Figure 52
Note: See circuit diagrams in the Appendix starting on

Weight transfer is enabled by opening the weight-transfer
shut-off valve , and controlled by two adjustment
valves ( and ).
The fold circuit is set to continuous flow (in unfold mode)
to maintain the active weight transfer.
The weight-transfer shut-off valve must be open for
weight transfer. When closed, it bypasses the reducing
valve for faster fold cylinder operation (and faster 2-point
lift-assist).
The pressure reducing valve controls the flow to the
cylinders.
The bypass valve returns excess oil to the tractor.
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
gauge during early field operations.

Wing Leveling
Before checking wing level, check that the center section
is level left to right (“Rear Eyebolt Adjustment”). On
2-point and Pull-Type, rear eyebolts above the rear
casters can affect left-right level if out of adjustment.
Wing Level: 2-Point and 3-Point
On 2-point and 3-point implements, wing level is
controlled entirely by gauge wheel height. If wings are
not running level, adjust gauge wheels.
Wing Level: Pull-Type
On pull-type implements, wing level is controlled by the
lift cylinders and the top eyebolt.
If wings get out of level, perform re-phasing operations
(page 45) until the lengths of the exposed rods are
identical across the implement.
If the wings are still not level, check that the eyebolt
reveal is still at the factory setting (or is at least identical
at all eyebolts).
Refer to Figure 55
The factory setting is a distance of:
3.5 inch (8.9 cm)
from the end of the eyebolt to the top face of the front
caster wheel lug tube.
To adjust the eyebolt, loosen the hose guide nut and
jam nut . Rotate the adjust nut to set bolt reveal.
Tighten jam nut.
Rear Eyebolt Adjustment
On 2-point and pull-type implements, side to side level at
rear is controlled by eyebolts at the lift cylinder bases. On
2-point, rear height is set by spacers (page 34).
On pull-type, rear height is controlled by the cylinders,
slaved to the hydraulic depth stop valve on the left wing.
Check that both eyebolts are set to the same reveal .
On pull-type, check front to back level (after re-phasing)
at full lift on level ground. If front eyebolts have been
changed from their factory settings, adjust the rear
eyebolts to bring the frame back into front-back level.
Refer to Figure 56
The factory setting is a distance of:
3.5 inch (8.9 cm)
from the end of the eyebolt to the top face of the lug tube.
To adjust the eyebolt, loosen the hose guide nut , then
the jam nut . Rotate the adjust nut to set bolt reveal.
Check that the hose loop is on top.
Tighten jam nut , then hose guide nut .

Unfold Stop Adjustment
This applies to 2013+ 2-Point 5-Section applicators only.
Refer to Figure 57
During unfold (FOLD / FIELD switch in FOLD), the inner
wing sections are intended to stop 0 to 5° above
wings-level relative to the center section . The stopping
point is controlled by a vertical proximity sensor at
each center/wing hinge. If a wing does not stop in this
range, adjust the proximity sensor.
1. Verify that the misalignment is not caused by air in
the hydraulic system. Do not use the proximity
adjustment to compensate for hydraulic problems.
2. Move the applicator to a level surface. Raise and fold
(page 49). Install lift-assist lock channels (page 38)
and parking stands (page 31).
3. Set the FOLD / FIELD switch to FOLD. Extend the
fold/lift circuit to unfold until the inner wings stop.
Set the circuit to Neutral. Shut off the tractor.
4. Check the sensor-actuator ( - ) gap at the
affected wing pivot. With the actuator near the
marked region on the sensor, the gap must be:
1
/8 to 1/4inch (3.2 to 6.3 mm)
If the gap is incorrect, correct that, at the current
sensor height. Fold and unfold to see if further
adjustment is required.
5. To adjust the sensor, loosen the bolts securing the
sensor to the bracket. Do not adjust the
actuator position.
To lower the angle at which the wing stops, raise the
sensor.
To raise the angle at which the wing stops, lower the

Caster Brake Adjustment
This applies only to pull-type and 2-point models.
Refer to Figure 59
The rear lift-assist wheels each have independent
adjusters for the caster pivot brake. The piston acts as
a pivot brake, and helps prevent caster oscillation during
transport. The adjustments will vary depending on
different field-to-field conditions as well as road transport
conditions.
If the caster is oscillating during transport turns or in field
use, adjust the pressure plate bolt .
Pressure Plate Adjustment
Refer to Figure 59 and Figure 60
The factory setting for a new piston is:
1. Loosen the jam nut .
2. Turn the bolt counterclockwise until the bolt is
turning freely.
3. Drive screw in (down) until it contacts spring plate .
4. Drive screw in until the bolt reveal (from top of
welded nut to bottom of bolt head) is:
2.0 inches (5.1 cm)
5. Tighten the jam nut.
Use more or less tension as needed to eliminate caster
vibration during highway transport. Adjust as needed to
compensate for piston wear.
Replace UHMW piston if its length is less than
1
1
/4inch (3.2 cm). Also replace piston if missing,
damaged, tilted, or top of piston is visible.
Pull-Type Wing Caster Brake Adjustment for Field
Use
1
On wing caster wheels only apply light pressure (
or less) to allow for easier swiveling of casters during
turning.

Setting Fertilizer Rate
For preset rate implements, rate is positively set by the
drive system and pump.
For variable rate implements, maximum rate is set by the
drive system and pump, and is reduced from that under
console control.
Adjustments to orifice plates must also be made to
provide back-pressure keeping the boom within a
specific pressure range to assure consistent delivery.
Setting the application rate requires the following steps:
1. Determine the rate (below),
in gallons per acre or liters per hectare.
2. Install suitable orifice plates (page 88).
3. Check strainer screen size (page 90).
4. Set the ground drive Range (page 91).
5. Set the ground drive dial (page 92).
6. Set the console rate (see 016-0159-831 Raven
SCS-450 Installation, Operation and Service
manual).
7. Check the manifold pressure and relief valve during
operation (page 91).
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.
The tables, and web calculator provided expect rates to
be expressed as
[U.S.customary] gallons per [U.S.Survey] acre or
liters per hectare.
The slide chart provided is gal/ac only.
If 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:

Material Loss or Misapplication Risks:
Orifice size must be appropriate for rate selected. Drop line
orifice plates do not affect rate. If orifice size is too small,
over-pressure in system may result in material loss at relief
valve. An orifice size too large may result in uneven
application across all rows.
When shutting off rows, review orifice sizing.

Select and Install Orifice Plates
If using VeriFlow nozzles, orifice plate instructions do not
apply. However, the topic “Tramlines and Doubled
Rows” on page 89 applies to all types of nozzles.
Agricultural Chemical Hazard:
Wear protective gloves when changing orifice plates. Consult
material manufacturer or supplier documents for proper
handling and steps to take if skin contact occurs.
Refer to Figure 61
Orifice plates at each drop line nozzle provide
back-pressure that balances flow in the manifolds,
assuring that each row obtains the same flow rate. For a
given rate, there may be more than one orifice size that
provides the recommended back-pressure.
Plates are provided with the system in three sizes.
Additional sizes are available. In general, the orifice
needs to be small enough to create a minimum pressure
in the manifold but large enough to prevent the manifold
pressure from exceeding the maximum:
15 psi min., 15-40 optimal, 65 psi max.
Using an orifice size too large can result in unequal flow
at rows. Using a size too small can cause excess
back-pressure resulting in material dumping at the relief
valve.
Determine Orifice Size
The chart below shows rate ranges for each Great Plains
orifice size and row spacing. You may need to change to
the next higher or lower orifice for a different fertilizer
solution density and/or a different ground speed.
To reduce orifice plugging and pump wear, use the
largest orifice practical for your fertilizer application rate.

Install Orifice Plates
Orifice plates are used only with the standard (TeeJet®)
nozzles.
Refer to Figure 62
Insert the plate inside the gasket supplied with the
nozzle . Insert the gasketed plate with the legend
side facing out the nozzle outlet (typically up).
In general, the orifice needs to be small enough to
create enough pressure in the manifold to operate the
check valves in the boom clamps, but not so much that
the system dumps product at the boom relief valve.
The recommend operating pressure is: 15 to 40 psi
Using an orifice size too large can result in unequal flow
at rows, intermittent flow, and flow stoppage at rows
where pressure falls below the 8 psi required to open the
clamp check valve. Using a size too small can cause
excess back-pressure resulting in material dumping at
the boom relief valve.
Use the same size at all active rows.
Excess Back-Pressure Risk:
If using a size of 0.048in or larger, remove the 828-046C
nozzle from the outlet of the coulter tine.
Tramlines and Doubled Rows
If your operations result in row units running in the same
row (or rows) in opposing passes, take steps to avoid
double application (run those rows at half rate).
• For doubled rows using standard nozzles, use orifice
plates having
Port Area of the other rows. See the table at right,
right-most column, for the Port Area of each plate
call size.
• For doubled rows using VeriFlow nozzles, install
829-144C half-rate nozzles on those rows.
For either nozzle type, an adjustment to the rate
calculation is required to compensate for the half-rate
rows. Reduce the applicator swath by
each row set to half rate.

than coulters, and include caps for unused rows.
When installing a cap:
Mis-Application or Material Loss Risk:
Do not apply materials after row shut-off or row turn-on
without first reviewing setup. Merely changing the number of
active rows does not change the application rate. If pump
and/or orifice size changes are not also made, pressures could
be too low or too high.
®
boom systems typically have more nozzles
• It is not necessary to remove the gasketed orifice
plate from inside the clamp. The cap includes its own
gasket that seals at the end of the clamp port.
• Use a tie wrap or other line to secure the loose
nozzle and drop line tubing to the boom.
• Adjust pump and/or orifice plates for new rate and
row spacing.
Strainer Adjustment
Refer to Figure 64
A Banjo brand strainer is supplied with the ground
drive fertilizer pump. It is plumbed before the
CDS-John Blue pump. The standard 80 mesh screen
should be suitable for most applications. A 50 mesh
screen is available from Great Plains. Other screen sizes
are available from Banjo Corporation.
If changing screen sizes, keep in mind the following.
• A smaller mesh (100) keeps very small manifold
orifice plates from plugging so often. However, the
screen requires cleaning more often.
• If using variable rate nozzles, Spray Target
recommends use of a 50 mesh screen with the
VeriFlow nozzles available from Great Plains (part
number LST-1550).
• A larger mesh (50) or (30) passes more material but
should only be considered when using large
manifold orifice plates.
• Mesh sizes below 30 are not recommended for use
with CDS-John Blue pumps.
• A plugged or partially plugged screen starves the
pump resulting in a reduced application rate.
• Mesh sizes: (Smallest) 100, 80, 50, 30 (Largest)

Setting Relief Valve
A relief valve is plumbed after the pump outlet to protect
the manifold and pump from excessive pressure. Any
product that activates the relief valve discharges from the
dump line .
To set relief valve:
Refer to Figure 65
1. Unlock plastic jam nut from relief valve knob .
2. Unscrew knob counter-clockwise until it loses
contact with internal spring.
3. Screw knob clockwise two turns. Start at this setting.
4. While operating in the field, observe manifold
gauge , and watch for relief valve discharge .
5. If valve is dumping product and gauge reads under
65 psi, stop tractor and turn knob clockwise (looking
down)
speed. Repeat this step as needed until no product
is discharged from relief valve.
6. If pressure gauge reads above 65 psi, change to a
larger orifice. Go to step 2. Repeat steps.

/4 turn. Continue operating at normal field
Set Pump Drive Range
Refer to Figure 66
Two Driving sprockets are provided for the pump:
Low Range: 15T
High Range: 47T
The choice of Driving sprocket depends on the
application rate desired. The pump adjuster dial (see
Figure 67) must be in the range 2-10 for consistent pump
rate.
Use the rate charts on page 81 through page 84 to
determine which Range to use for the rate desired.
For implements with optional variable rate capability,
choose the sprocket which, at dial setting 10, provides a
rate higher than the maximum you intend to use. If Low
range suffices, use it for reduced pump wear.
To change Driving sprocket:
1. Loosen the bolt securing the rear idler . Slide the
idler forward. Lift the chain off the lower Driving
sprocket.
2. Remove pins at the storage and Driving shafts.
3. Exchange sprockets. Re-pin.
4. Re-engage idler for slack of
longest chain span .

1. Loosen the nut at the setting pointer.
2. Use the setting wrench to rotate the dial until the
desired pump setting is under the pointer .
Note: Settings below 2 are not recommended. If
presently using High range, switch to Low range
and use the dial setting for your rate in Low range.
3. Tighten the nut.
Material Loss/Equipment Damage Risks:
Operate only with material loaded, or disconnect chain or
remove sprocket if not intending to apply material. Ground
drive wheel and chain system operate whenever the implement
is lowered and in motion. The pump must not be run dry.
Sensor Adjustment
The proximity sensor on the left-hand side of the front
of the machine is for starting the gull winging process.
This sensor should be set to activate by the upper lift
arm. Once the arm passes the sensor, the gull winging
process will begin. The rear proximity sensors are
located near the wing hinges. They control the height or
angle of the gull winging process.
All three sensors should be given between 1/8-1/4”
clearance.
To adjust, loosen the hardware securing the sensor,
then slide the sensor up or down in the bracket. The
further the sensor is raised in the bracket the more
delayed the gull winging process will be. Once the
sensor is set to the desired position, secure the sensor
with hardware. Test this configuration by lifting and gull
winging the wings of the machine. If you want gull
winging to delay or hasten the process more, make
further adjustments until satisfied.

Excess Wear Risk:
Check that the Terra-Tine™ Row Cleaner tines DO NOT touch
the coulter blade or any other attachments. Such contacts
cause excess wear to all parts involved. At least
clearance is recommended.
1. When the blade is out of the soil, adjust the lock
collar height to set the height of tine fingers flush with
the bottom of coulter blade.
2. Side-to-side alignment can be done by rotating the
shank mount around the vertical shaft and
retightening the square head set screw.

quicker than the flow-based adjustment, and delivers no
material to the tines.
1. Fill tank(s) with water or fertilizer.
2. Set hydraulic remote circuit for pump to Float.
Set flow rate to minimum.
3. Set tank discharge and selector valves to enable
material flow from tank(s) to the pump.
4. Set the Console FLOW switch to MAN.
5. Set MASTER switch OFF.
