Maximum transport speed for implement is 20 mph. Some rough terrains
require a slower speed. Sudden
braking can cause a towed load to
swerve and upset.
▲ 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.
▲ Comply with state and local laws.
▲ Do not tow an implement that,
when fully loaded, weighs more
than 1.5 times the weight of towing vehicle.
Use A Safety Chain
▲ Use a safety chain to help con-
trol drawn machinery should it
separate from tractor drawbar.
▲ Use a chain with a strength rat-
ing equal to or greater than the
gross weight of towed machinery.
▲ Attach chain to tractor drawbar
support or other specified
anchor location. Allow only
enough slack in chain to permit
turning.
▲ Replace chain if any links or end
fittings are broken, stretched or
damaged.
▲ Do not use safety
chain for towing.
Practice Safe Maintenance
▲ Understand procedure before
doing work. Use proper tools and
equipment. Refer to this manual
for additional information.
▲ Work in a clean, dry area.
▲ Lower implement to ground, put
tractor in park, turn off engine,
and remove key before performing
maintenance.
▲ Allow implement to cool completely.
▲ Inspect all parts. Make sure parts
are in good condition and installed
properly.

impairment or hearing loss, wear
suitable hearing protection such
as earmuffs or earplugs.
▲ Because operating equipment
safely requires your full attention,
avoid wearing radio headphones
while operating machinery.
Avoid High
Pressure Fluids Hazard
Escaping fluid under pressure can
penetrate skin, causing serious
injury.
▲ Avoid the hazard by relieving
pressure before disconnecting
hydraulic lines.
▲ Use a piece of paper or card-
board, 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, see a doc-
tor immediately. Any fluid injected
into the skin must be surgically
removed within a few hours or
gangrene may result.
Safety at All Times
Thoroughly read and understand this
manual before operating implement.
Refer to Safety Decals, page 4. Read
all instructions noted on decals.
▲ Be familiar with all implement
functions.
▲ Operate implement from driver’s
seat only.
▲ Do not leave tractor or implement
unattended with engine running.
▲ Do not dismount a moving tractor.
Dismounting a moving tractor could
cause serious injury or death.
▲ Do not stand between the tractor
and implement during hitching.
▲ Keep hands, feet and clothing
away from power-driven parts.
▲ Wear snug-fitting clothing to avoid
entanglement with moving parts.
▲ Watch out for wires, trees, etc.,
when raising implement. Make
sure all persons are clear of working area.
▲ Do not turn tractor too tightly,
causing implement to ride up on
wheels.
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 to allow 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.

Introduction
Great Plains welcomes you to its growing family of new
product owners. This implement has been designed with
care and built by skilled workers using quality materials.
Proper setup, maintenance and safe operating practices
will help you get years of satisfactory use from the machine.
Description of Unit
The Precision Hitch is a pull-type tillage implement designed to tow a Great Plains three-point drill. No-till
coulters are mounted on the hitch. Each coulter is aligned
with a drill opener. The coulters till strips for the drill openers. The hitch has two hydraulic circuits: one for raising
and lowering the coulters and one for raising and lowering
the drill.
The hitch can be outfitted with fertilizer coulters, a drive
system, a piston pump and tanks for liquid-fertilizer application. With coulters set at various spacings, the hitch can
be used to apply fertilizer in the row below the seedbed at
rates from 4 to 80 gallons per acre. Total combined tank
capacity is 400 gallons.

Section 1 Preparation and Setup
Bleeding Air from Hydraulics
Escaping fluid under pressure can have sufficient force to penetrate the skin. Check all hydraulic lines and hoses before applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor that is familiar with this kind of injury. Foreign
fluids in the tissue must be surgically removed within a few
hours or gangrene will result.
You could be severely injured or killed by being crushed under
the falling implement. Always have transport locks in place and
frame sufficiently blocked up when working on implement.
The hydraulics must be bled of air before hitch operation.
If the hydraulics are not bled, the cylinders will move with
jerky, uneven motions. The hydraulics should be bled during initial hitch setup. If the hydraulics have not be bled, or
if you replace a hydraulic component during the life of the
drill, follow these procedures.
Bleeding Tongue Cylinder
1. Check hydraulic fluid in tractor reservoir and fill to
proper level. Add fluid to system as needed. Tongue
cylinder capacity is one-half gallon (1.89 liters).
2. Raise and safely support hitch, transport frame and
front tongue.
3. Unpin rod end of tongue cylinder. Block, wire or otherwise safely support cylinder so when rod end is fully
extended it does not contact anything.
4. Cycle cylinder completely in and out at least three
times to purge air from cylinder and hoses.
5. Fully extend cylinder and repin rod end.
6. Recheck tractor reservoir and fill to proper level.
Bleeding Transport Lift Cylinders
1. Check hydraulic fluid in tractor reservoir and fill to
proper level. Add fluid to system as needed. Cylinder
capacity is about 2 gallons (7.57 liters).
2. Jack up and support hitch frame.
3. Unpin rod ends of cylinders. Block, wire or otherwise
safely support cylinders so when rod ends are fully extended they do not contact anything.
4. Cycle cylinders in and out completely at least three
times to purge air from cylinders and hoses.
5. Fully extend cylinders and repin rod ends.
6. Recheck tractor reservoir and fill to proper level.
Hooking Hitch to Drill
You may be severely injured or killed by being crushed between
the hitch and drill. Do not stand or place any part of your body
between the drill and moving hitch. Stop tractor engine and set
park brake before installing hitch pins.
This hitch could have negative tongue weight when hitched to a
three-point drill in the raised position. Negative tongue weight
will cause the unsecured hitch tongue to raise suddenly and
could cause injury or death. Always lower drill before unhooking hitch from tractor.
1. Place hitch extension (1) between top hitch plates on
drill. Bolt hitch extension in place as shown in Figure
1-3 using two 1-by-5 1/2-inch bolts (2), lock washers
(3) and hex nuts (4).

Hooking Up Hydraulic Hoses
Escaping fluid under pressure can have sufficient force to penetrate the skin. Check all hydraulic lines and hoses before applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor that is familiar with this kind of injury. Foreign
fluids in the tissue must be surgically removed within a few
hours or gangrene will result.
Great Plains 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 Hydraulic Function
Red Tongue Cylinder
Blue Transport Lift Cylinders
Orange Marker Cylinders
To distinguish hoses on the same hydraulic circuit, refer to
plastic hose holder. See Figure 1-7. Hose under extended-cylinder symbol feeds cylinder base ends. Hose under
retracted-cylinder symbol feeds cylinder rod ends.
4. Position hitch in front of drill so quick-hitch links on
hitch are in line with lower hitch pins on drill. Hydraulically retract transport-lift cylinders to position quickhitch links slightly lower than drill hitch pins.
5. Back hitch up to drill until hitch pins contact quick
hitch. Hydraulically raise hitch just until drill hitch pins
are secure inside quick-hitch links. Do not raise drill
any higher than necessary.
6. Visually confirm that pins are seated and latches have
snapped out over the pins.
7. Attach slotted link bar (1) to top hitch extension on
drill. Use 1-by-3 3/4-inch pin (2) and bushing (3) to pin
level-link bar to drill. Secure pin with clip provided (4).

Section 2 Operating Instructions
This section covers general operating procedures. Experience, machine familiarity and the following information will
lead to efficient operation and good working habits. Always operate farm machinery with safety in mind.
Prestart Checklist
1. Carefully read “Important Safety Information,” beginning on page 1.
2. Lubricate implement as indicated under Lubrication,
“Maintenance and Lubrication,” page 33.
3. Check all tires for proper inflation as indicated on Tire
Inflation Chart,“Appendix,” page 40.
4. Check all bolts, pins and fasteners. Torque as specified on Torque Values Chart,“Appendix,” page 40.
5. Check implement for worn or damaged parts. Repair
or replace before going to the field.
6. Check hydraulic hoses, fittingsand cylinders for leaks.
Repair or replace before going to the field.
Field Operation
You may be severely injured or killed by being crushed between
the tractor and hitch. Do not stand or place any part of your
body between hitch and moving tractor. Stop tractor engine and
set park brake before installing the hitch pin.
2. Move transport-lock handle to field position. See Figure 2-1.

Figure 2-1
Transport-Lock Handle, Field Position
3. Remove cylinder lock channel from tongue cylinder.
See Figure 2-2.
Escaping fluid under pressure can have sufficient force to penetrate the skin. Check all hydraulic lines and hoses before applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor that is familiar with this kind of injury. Foreign
fluids in the tissue must be surgically removed within a few
hours or gangrene will result.
1. Hook hitch to a suitable tractor and drill. Refer to
Hooking Hitch to Tractor and Hooking Hitch to Drill,
“Preparation and Setup,” page 8.

4. Set and calibrate drill seeding rate. Refer to drill operator’s manual.
5. Adjust coulters for necessary down pressure and desired depth. Refer to Coulter Depth,“Adjustments,”
page 29, or Coulter Command Adjustments,“Adjust-
ments,” page 29, and Coulter Down Pressure,“Ad-
justments,” page 19, for adjustment instructions.
6. Adjust drill seeding depth. Refer to drill manual.
7. Level hitch and drill. Refer to Leveling Adjustment,
“Adjustments,” page 22.
8. Pull forward, lower coulters and drill, and begin seeding.
9. After seeding for a short distance, stop with the drill
and hitch in the ground. Inspect the drill for proper operation including the following:
• Confirm that the automatic pivot locks have raised,
so the hitch is free to articulate and track properly on
curves. (See Pivot Locks, page 16, for more information.)
• Confirm that seed is being metered.
• Check seed depth.
10. Always lift drill out of ground when turning at row ends
and for other short turns. Seeding and fertilizer application will stop automatically as you raise the coulters
and drill for field turns. The hitch’s pivot locks will also
engage while turning.
Fertilizer Application Option
plumbing manifold mounted along the coulter toolbar.
An orifice is installed under the quick cap on each manifold
outlet. The orifice creates a small amount ofback pressure
in the manifold and prevents the outlets nearest the pump
from getting too much of the total flow.
Since the pump is a positive displacement pump, the overall application rate is determined by the pump setting
(stroke) and the size of the pump driver sprocket. The size
of the orifice does not affect the application rate.
To operate the liquid-fertilizer system, follow these steps:
1. Choose a sprocket range and pump setting for your
desired application rate. Refer to Fertilizer Application
Rates,“Adjustments,” page 23.
2. Adjust driver sprocket and pump setting as necessary.
Refer to Adjusting Fertilizer Rates,“Adjustments,”
page 23.
3. Choose proper orifice to match your application rate.
Install proper orifice plates. Refer to Orifice Plates,
“Adjustments,” page 24.
4. Adjust fertilizer tines to correct position. Refer to Ad-
justing Fertilizer Tines,“Adjustments,” page 25.
5. Set manifold relief valve. Refer to Setting Relief Valve,
“Adjustments,” page 25.
6. Fill fertilizer tanks.
a. Connect nurse-tank hose to quick-fill coupler
shown in Figure 2-4. Lock hose in place with camlock levers.

Some chemicals will cause serious burns, lung damage and
death. 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. Seek medical assistance
immediately if accident occurs. Know what to do in case of an
accident.
The fertilizer-application system uses a piston pump. The
pump is ground driven. The pump moves fertilizer into a

d. Fill tanks, then close valve at quick-fill coupler,
and disconnect the nurse tank hose.
Always fill fertilizer tanks to equal levels. If one
tank fills more quickly, shut that tank valve off to
raise the level in the other tank.
Note: The tank shutoff valves supplied from the factory are 3-way ball valves with the ports facing the rear of the machine
plugged. With this port plugged use the valves as standard on/off valves. The 3-way valves have been provided to make
a conversion to a dual product system easier. By removing the plugs on the rear port of the 3-way valves, and by adding
some additional plumbing and a second pump, the unit can be used in these scenarios:
a. Both tanks hold product 1. (example starter). Both tanks are routed to the starter pump by turning the 3-way
valves forward.
b. One tank holds product 1, the other tank product 2. Fill the tanks one at a time through the same quick fill line.
Supply two different pumps the two different products by turning on valve handle forward, and the other handle
rearwards.
c. Both tanks hold product 2. Both tanks are routed to the second pump by turning both handles rearwards.
Always turn the long part of the handle to point the direction you want the product to flow. Setting the handle at 90 degrees
to the side ports shuts off the flow to all ports.

By watching the manifold pressure when operating at
field speeds, you can confirm that you have the correct orifice plates needed to keep the manifold pressure between 5 psi and 85 psi. If the gauge reads
below 5 psi or above 85 psi, use different orifice
plates.
If the gauge reading increases slowly over time, check
for plugging at the orifice plate(s) under the quick
cap(s) or at the nozzle behind the coulter blade. If the
gauge reading drops suddenly, check for empty tanks,
or a disconnected pump supply hose.
Marker Option
Optional marker attachments are available from your
Great Plains dealer. Before operating markers, make sure
hydraulics have been bled properly.
The dual markers are equipped with a sequence valve and
are powered off one hydraulic circuit. Starting with both
markers folded, the folding sequence is:
1. Activate lever – Right unfolds; left stays folded.
2. Reverse lever – Right folds up; left stays folded.
3. Activate lever – Left unfolds; right stays folded.
4. Reverse lever – Left folds up; right stays folded.
5. Sequence repeats.
You can adjust marker folding speed. Refer to Marker Ad-
justments, “Adjustments,” page 28, and adjust folding
speed to a safe rate. Folding markers at high speed can
damage markers.
Pivot Locks
Pivot-locks are located in front of the transport frame. The
tubes provide stability during hitch transport. When hitch
is raised, pivot-lock tubes rotate down to restrict hitch pivoting. When hitch is lowered, pivot-lock tubes rotate up
and allow hitch and frame to pivot freely in the field.
In most field conditions, allow pivot-lock tubes to raise and
lower automatically. Store pin shown in Figure 2-1 in its
storage hole (1).
When planting on steep slopes or when backing hitch during hookup, up may need to lock the tubes for increased
stability. To lock tubes, insert pin over lowered tubes (2) as
shown in Figure 2-1.

Transporting
Towing the implement at high speeds or with a vehicle that is
not heavy enough can lead to loss of vehicle control. Loss of vehicle control can lead to serious road accidents, injury and
death. To reduce the hazard:
• Do not exceed 20 mph (32 kph).
• Secure transport locks and channel as explained below.
• Do not tow an implement that, when fully loaded, weighs
more than 1.5 times the weight of the towing vehicle.
• Unload all liquid fertilizer from implement tanks before
transporting.
1. Check that hitch is hooked securely to a sufficient tractor. Refer to Hooking Hitch to Tractor,“Preparation
and Setup,” page 8.
2. Unload liquid fertilizer from hitch tanks.
3. Unload drill seed box before transporting if at all possible. The implement can be transported with a full box
of grain, but the added weight will increase stopping
distance and decrease maneuverability.
4. Check that tires are properly inflated. Refer to Tire In-
flation Chart,“Appendix,” page 40.
5. Hydraulically raise coulters and lift drill.
6. Move transport-lock handle to road position. See Figure 2-2.
7. Check that the transport locks are engaged.
8. Pin cylinder-lock channel over extended rod on
tongue cylinder. See Figure 2-3.
9. Know implement dimensions in transport position.
Choose a route that provides adequate clearance
from all obstructions. Refer to “Specifications and
Capacities,” page 39, for dimensions.
10. Comply with all laws when traveling on public roads.

Parking
This hitch could have negative tongue weight when hitched to a
three-point drill in the raised position. Negative tongue weight
will cause the unsecured hitch tongue to raise suddenly and
could cause injury or death. Always lower drill before unhooking hitch from tractor.
Perform the following steps when parking implement. Refer to Storage,“Maintenance and Lubrication,” page 32,
for information on long-term storage.
1. Park implement on a firm, level area. Lower coulters
and drill to ground.
2. Block tires securely to prevent rolling.
3. Release pressure on hydraulic system, then disconnect hydraulic lines. Position hoses on hitch tongue so
hose ends do not rest on ground.
4. Move jack from transport position and place it on stob
on side of hitch tongue.

Section 3 Adjustments
Coulter Depth
A no-till coulter is mounted on the hitch directly ahead of
each opener on the drill. The coulters cut through heavy
trash and make a groove in the soil for the openers.
The hitch is designed to allow coulters to penetrate approximately two inches (5 centimeters) into the soil when
the tongue is level. Depth can be adjusted hydraulically for
all coulters or manually for individual coulters. Adjust
coulters 1/2 to 1 inch deeper than the drill openers.
NOTE: If your implement has the optional Coulter Command system, refer to Coulter Command Adjustments,
page 20, for information on adjusting coulter depth.
Hydraulic Control
Make the following adjustment when drilling in level
ground with the seed box half full. Extend or retract tongue
cylinder so that coulters are at desired depth. Note setting
on cylinder gauge (see Figure 3-1) so that you can return
to the same depth.
1. Extend or retract tongue cylinder so that coulters are
at desired depth. Note setting on cylinder gauge (see
Figure 3-1) so that you can return to the same depth.
NOTE: Use cylinder gauge as a reference only. Gauge
does not measure actual coulter depth.
4. Finish tightening hex-head clamp bolts.

Figure 3-2
Individual Coulter Mounting
NOTE: Even when coulter is held securely, there may be a
gap between clamp halves.
Coulter Down Pressure
The amount of coulter down pressure needed to cut a soil
groove varies with soil conditions. Hard soil or heavy crop
residue may cause shallow penetration. If coulter penetration is different than desired, add weight or shorten coulter
springs to improve coulter penetration.
Added Weight
In hard soil conditions where coulter penetration is limited,
you can add suitcase weights to brackets on hitch frame.
Adding weight on hitch frame provides best weight distribution for no-till drilling.You can add up to 2,000 pounds of
additional weight. Place an equal amount of weight on
each weight bracket.

Cylinder Gauge
Coulter Mounting Height
You can change the depth of individual coulters by adjusting coulter-mounting height. If you adjust coulter height,
be sure to rebolt coulters vertically straight and spaced
correctly. To raise or lower an individual coulter:
1. Loosen mounting clamps and adjust coulter to desired
height. Do not lower coulter spring bar below top ubolts on coulter clamp.
2. To retighten clamps, refer to Figure 3-2. Snug hex-
head clamp bolts (1) just until u-bolts are tight on each
side of spring bar.
3. Tighten nuts (2) on u-bolts.

Coulter Springs
Coulter spring length is preset at the factory to 10 inches,
giving coulters an initial operating force of 400 pounds
(181 kg). This setting is adequate for many difficult no-till
conditions. For lighter no-till conditions where rocks or other obstructions are a problem, you can reduce spring load
to give coulters better impact protection. Refer to the following chart when adjusting coulter spring length.

No-Till or Hard, Dry Soil Conditions
For maximum opener penetration, operate drill and hitch
in rigid position. See Figure 3-5. The rigid position is the
most common position for no-till seeding and is effective
for a wide range of field conditions. Lock plate down over
top link pin.

For softer soils that have been tilled lightly and for drilling
over hills, contours, ditches or terraces, operate drill in limited-float position. See Figure 3-6. Leave lock plate unlocked and adjust level link so top link pin is at back of slot.
(Refer to Leveling Adjustment, page 22.) The limited-float
position allows hitch and drill to flex when traveling over
contours but transfers enough weight to drill for opener
penetration in softer soils.

Fertilizer Application Option
The fertilizer-application system uses a piston pump. The
pump is ground driven. The pump moves fertilizer into a
plumbing manifold mounted along the coulter toolbar.
An orifice is installed under the quick cap on each manifold
outlet. The orifice creates a small amount of back pressure
in the manifold and prevents the outlets nearest the pump
from getting too much of the total flow.
Remember, application rates are determined by pump
setting and size of pump driver sprocket. Orifice size does
not affect the application rate.
The following instructions and rate chart apply to the John
Blue model LM-2455 piston pump sold as an option with
the PFH-15 and PFH-20.
Adjusting Fertilizer Application Rate
1. Refer to rate chart. Find your desired application rate
and note sprocket range (high or low) and pump setting required for your desired application rate.
2. Set sprocket range. Check the number of teeth on the
driver sprocket. See Figure 3-9.
• For low range, use the 23-tooth sprocket
• For high range, use the 47-tooth sprocket
3. Set pump. Loosen scale-setting nut (1) on side of
pump-calibration dial. Use special wrench (2) from
John Blue to rotate notched disk until pointer is at desired setting. Tighten scale-setting nut, being careful
not to over tighten nut. See Figure 3-10.
NOTE: The adjustment wrench can be stored in a slot (3)
provided in the pump mount bracket.

Strainer
A Banjo brand strainer is supplied with the fertilizer pump
option and is to be plumbed before the John Blue pump.
The standard 80 mesh screen should be suitable for most
applications. Other screen sizes are available from Banjo
Corporation. If changing screen sizes, keep in mind the
following.
• A smaller mesh (100) will keep the very small manifold orifice plates from plugging so often. However,
the screen will have to be cleaned more often.
• A larger mesh (50) or (30) will pass more material
but should only be considered when using large
manifold orifice plates.
• A plugged or partially plugged screen will starve the
pump and will result in a reduced application rate.
• John Blue recommends using a 30 mesh screen or
tighter to protect their pump.
• Mesh sizes: (Smallest) 100, 80, 50, 30 (Largest)
Orifice Plates
In general, the orifice needs to be small enough to create
at least 5 psi of pressure in the manifold but large enough
to prevent the manifold pressure from exceeding 85 psi. To
reduce orifice plugging and pump wear, use the largest orifice practical for your fertilizer application rate.
The PFH-15 and PFH-20 have 0.048-inch orifices as standard equipment. You can order the other Tee-Jet orifices
listed on the following chart from your Great Plains dealer.
Many other orifice sizes are available through Tee-Jet.
To choose and install the proper orifice plate:
1. Find your hitch width and row spacing on the chart.
2. Select the largest orifice that includes your application
rate.

*Orifice-48 is provided as standard equipment with manifold. Orifices of other sizes must be ordered. Contact your Great
Plains dealer.
TIP: When using very low application rates, you may find that the small orifices plug too often. Consider adding water to
your fertilizer and increasing the rate. This will allow you to switch to a larger orifice.
Example: 10 GPA original rate. (1) Mix 200 gallons of fertilizer with 200 gallons of water. Your product is now at half
strength. (2) Double your application rate to 20 GPA. Your ACTUAL fertilizer rate is still 10 GPA.

Setting Relief Valve
A relief valve is mounted directly above the pump to protect the manifold and pump from excessive pressure. Any
product that dumps over the relief valve will discharge
from the dump line (1).
To set relief valve:
1. Unlock plastic jam nut (2) from relief-valve knob.
2. Unscrew knob (3) counterclockwise until it loses contact with internal spring.
3. Screw knob clockwise two turns. Start at this setting.

Set Relief Valve
When positioning tines:
• Set fertilizer tines so bottom of tines are about 1 to 1
1/2 inch below the soil surface. You can set the tines
deeper, but you risk causing excessive wear and
plugging.
• Set tines about 1 to 1 1/2 inch behind the coulter
blade in a vertical or slightly back swept position.
• Set tines in line with the coulter blade.
4. Observe manifold gauge and watch for relief-valve
discharge while operating in the field.
• If valve is dumping product and gauge reads under
85 psi, stop tractor and turn knob clockwise 1/4 turn.
Continue operating at normal field speed. Repeat
this step as needed until no product is discharged
from relief valve.
• If the pressure gauge reads above 85 psi, change to
a larger orifice, following the guidelines in the orifice
selection table. Go to step 2 and repeat steps.
Adjusting Fertilizer Tines
Your main objective when adjusting the fertilizer tine is to
position the nozzle so it sprays into the void created by the
slicing action of the coulter blade. This allows the nozzle to
inject fertilizer to the bottom of the trench.

Side to Side Adjustment Fertilizer Tine
The fertilizer tine must be straight with the coulter blade
and centered behind the coulter blade. To alter the side to
side rotation of the tine:
1. Remove 1/2-inch, hex-flange nut and flat washer (1)
holding tine (2) on back arm (3).
1. Center tine behind coulter blade by adding or removing rectangular spacer washers (4) that fit between
back arm and fertilizer-tine clip (5). Store unused
spacer washers on opposite side of back arm.
2. If a finer adjustment is needed to center tine behind
coulter blade, place a 1/2-inch flat washer (6) between
front arm and back arm to shim them apart. Store unused washers on outside of back arm under 1/2-inch
flange nuts (7).
3. When tine is centered behind coulter blade, adjust tine
so it is aligned vertically with the coulter blade. If necessary, remove hex-flange nuts (7) holding back arm
to front arm. To rotate bottom of tine counterclockwise,
place one 1/2-inch flat washer between front arm and
back arm on upper hex-flange bolt (8). To rotate bottom of tine clockwise, place one 1/2-inch flat washer
between front arm and back arm on lower hex flange
bolt (9). Retighten hex flange nuts and store extra
washers behind hex-flange nuts.
Front to Back Adjustment
1. Loosen hex flange nuts (7) holding back arm to front
arm.
2. Rotate back arm assembly until tine is in a vertical or
slightly swept back position and between 1 to 1 1/2
inch behind coulter.
3. Retighten hex flange nuts.
Up and Down Adjustment
1. To adjust tine depth, remove 1/2-inch hex flange nut
and flat washer (1) holding coil tine (2) to back arm (3).
2. Position tine to desired height by placing hooked end
of the coil tine (10) in one of the five holes in back
plate.
3. Secure tine to back arm by reassembling 1/2-by-4 1/2inch bolt (11) through round spacer tube (12), clip,
rectangular spacers and back arm. Secure with a flat
washer and hex flange nut.

Leaf Spring Adjustment
A leaf spring is located just ahead of the vertical pivot. See
Figure 3-22 Leaf Spring AdjustmentFigure 3-22. The
spring is designed to provide just enough force to keep the
hitch square and stable for turning at field ends and to add
stability for drilling in rough field conditions. Proper leafspring adjustment is important for smooth implement
operation.
To adjust properly, refer to . Square tongue with transport
frame and adjust 3/8-inch u-bolts (1) on each side until
leaf-spring rollers (2) just make contact with roller pads (3)
on transport frame. Make sure both right and left sides are

Maintenance
You could be severely injured or killed by being crushed by the
falling implement. Always have transport locks in place and
frame sufficiently blocked up when working on implement.
This hitch could have negative tongue weight when hitched to a
three-point drill in the raised position. Negative tongue weight
will cause the unsecured hitch tongue to raise suddenly and
could cause injury or death. Always lower drill before unhooking hitch from tractor.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, and
wear heavy gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with this type
of injury. Foreign fluids in the tissue must be surgically removed
within a few hours or gangrene will result.
fer to Safety Decals,“Important Safety Information,”
page 4, for decal placement.
5. Check hitch safety chain. Make sure chain is properly
attached to hitch. Inspect chain for wear or other damage. Replace immediately if needed.
6. Check fertilizer drive chains for wear. Replace if necessary. Adjust idlers to remove excess slack from
chains.
Marker Maintenance
The marker arm is attached to marker body with a 3/8inch, grade 2, shear bolt. If shear bolt breaks, replace it
with a grade 2 bolt.
If grease-seal cap for marker disk bearings is damaged or
missing, disassemble and clean hub. Repack with grease
and install a new seal or grease cap.
Fertilizer Cleanout
Some chemicals will cause serious burns, lung damage and
death. 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. Seek medical assistance
immediately if an accident occurs. Know what to do in case of
an accident.
Coulter and opener disks may be sharp enough to cut flesh. Be
careful when working around coulter and opener disks.
Proper servicing and maintenance is the key to long implement life. With careful and systematic inspection, you can
avoid costly maintenance, downtime and repair.
Always turn off and remove tractor key before making any
adjustments or performing any maintenance.
1. After using implement for several hours, check all
bolts to be sure they are tight. Check all valves, fittings, hose clamps and plugs to be sure they are tight.
2. Inflate tires as specified on Tire Inflation Chart,“Ap-
pendix,” page 40.
3. Lubricate hitch as listed under Lubrication, page 33.
4. Replace any worn, damaged or illegible safety decals.
Obtain new decals from your Great Plains dealer. Re-
Proper and regular cleanout is the best way to prolong piston-pump life. Do not allow air to enter the pump, even for
short periods of time. Air in the pump will cause rapid and
severe corrosion.
After each day’s use:
1. Flush tanks, nozzles, hoses and pump with clean water. Do not allow air into the pump.
2. Do not drain the pump. Leave fresh water in pump
overnight.
3. Wash any components that may have been exposed
to fertilizer.
For two- to three-week storage:
After flushing fertilizer system with water, immediately fill
all pump passages with motor oil. Replace pump manifold
and plug pump inlet and outlet with a stopper or oily rag.
