Keep Riders Off Machinery
A rider on machinery is subject to injury such as being
struck by foreign objects or
being thrown off the machine. A rider obstructs the
operator’s view, resulting in
unsafe machine operation.
Keep riders off any machinery while in operation. Allow only skilled persons to operate machinery.
Great Plains Mfg., Inc.
Important Safety Information
Use Safety Lights and Devices
Slow moving tractors, self-propelled
equipment and towed implements or at-
tachments can create a hazard when
driven on public roads, and are difficult to
see, especially at night.
Flashing warning lights and turn signals
are recommended whenever driving on
public roads. Use the lights and devices
provided with your machine.
Keep safety signs and lights in good condition. Replace
any missing or damaged items.
Transport Machinery Safely
Comply with state and local laws when
transporting machinery.
Maximum transport speed for planter is 20
mph. DO NOT EXCEED. Never travel at a
speed which does not allow adequate con-
trol of steering and stopping.
Braking from transport speed can cause a
towed load to swerve and upset. Reduce
speed if towed load is not equipped with
brakes.
Use the following recommended speed-
weight ratios as a guideline:
● Maximum speed of 20 mph when weight
of towing load is less than or equal to the
weight of your tractor.
● Reduce speed to 10 mph when weight of towed load
is up to double the weight of your tractor.
● Do not tow a load which is more than double the
weight of your tractor.
Use a Safety Chain
A safety chain will help
control drawn machin-
ery should it separate
from the tractor draw-
bar.
Use a chain with the
strength rating equal to
or greater than the gross weight of the towed machin-
ery.
Attach the chain to the tractor drawbar support or other
specified anchor location. Allow only enough slack in
the chain to permit turning.
Do not use safety chain for towing.
Avoid High Pressure Fluids Hazard
Escaping hydraulic oil can have ex-
tremely high pressure which can
penetrate the skin causing serious
injury.
Avoid this hazard by relieving all hy-
draulic pressure before disconnect-
ing any lines. Be sure all connections are tight before
applying pressure.
Protect hands and body from high pressure fluids. Use
a piece of cardboard or wood to detect leaks.
If an injury is caused by escaping hydraulic fluid. SEE A
DOCTOR IMMEDIATELY! The fluid must be surgically
removed within a few hours or gangrene will result
Practice Safe Maintenance
Understand maintenance proce-
dure before doing work. When ser-
vicing machine use proper tools
and equipment. Refer to operator’s
manual.
Keep hands, feet, and clothing
away from power-driven parts. Dis-
engage all power and relieve pres-
sure.
Lower machine to the ground. Stop
tractor engine and remove the key.
Allow machine to cool before ser-
vicing.
Keep the area clean and dry.
Securely support machine compo-
nents that will be raised during service.
Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on ma-
chine.
Make sure all parts are properly installed and in good
condition. Fix any damage immediately and replace
worn or broken parts. Remove buildup of grease, oil or
debris.
Prior To Operation
1. Practice safety by always thinking before acting.
2. Make sure safety rules are understood before operating machine or tractor.
3. Loose fitting clothing should not be worn as it may catch in
moving parts.
4. Never attempt to operate the implement unless you are in
the driver's seat.
5. Never dismount from a moving tractor.

6. Do not leave the tractor or the implement unattended with
the engine running.
7. Do not stand between the tractor and the implement during
hitching.
During Operation
1. Never allow the planter to be operated by anyone who is un-
familiar with the operation of all functions of the unit. All
operators should read and thoroughly understand the instructions given in this manual prior to moving the unit.
2. Never permit any persons other than the operator to ride on
the tractor.
3. Regulate your speed to the field conditions, maintaining
complete control at all times.
4. Always lower the implement and shut off the tractor engine

5. Do not grease or oil machine while it is in operation.
6. Always make sure there are no persons near the planter
when the marker assemblies are in operation.
7. Watch for obstructions such as wires, tree limbs etc., when
folding markers.
8. If a hydraulic leak develops, correct it immediately. Escaping hydraulic oil can have extremely high pressure. A
stream of high pressure oil may easily penetrate the skin as
with modern needless vaccination equipment - but with the
exception that hydraulic fluid may cause blood poisoning. It
is imperative that the connections are tight and that all lines
and pipes are in good condition. If an injury is caused by the
escaping hydraulic fluid, see a doctor at once!
After Operation
1. Detach and store implements in an area where children nor-
mally do not play. Stabilize implements by using suitable
supports and block wheels.
During Maintenance
1. After repairing or adjusting, make sure all tools and parts
are removed from the implement before attempting to operate it.
2. Never work under a raised planter.
3. Disk edges are sharp! Be careful when working in this area.
4. Use a piece of cardboard or wood to detect leaks of hydraulic oil under pressure.
5. Be sure to relieve all hydraulic pressure before disconnection any lines or pipes between the implement and the tractor hydraulic system. Keep all guards and shields in place.
Transporting
1. Before transporting make sure the hitch is securely attached
to the draw bar of the tractor and the safety chain is connected.
2. Be alert to traffic when crossing or operating near road-
ways. Always maintain complete control of the machine.
Know your state and local laws concerning highway safety
and regulations. Comply with these laws when transporting
machinery.
3. Do not exceed 20 mph when transporting. Transport only
with a farm tractor of sufficient size and horse power. See
Tractor Preparation in “Section 2 Planter Operation”
on page 13.
4. Always make sure flashing safety lights, slow moving vehi-
cle emblem, and reflectors are in place and visible prior to
transporting the machine on public roads, when required.
5. Do not transport at night or during other periods of poor
visibility.
Tire Handling & Repair
1. Tire changing can be dangerous and should be preformed
by trained personnel using the correct tools and equipment.
2. Do not re-inflate a tire that has been run flat or seriously
under inflated. Have it checked by qualified personnel.
3. When removing and installing wheels, use wheel handling
equipment adequate for the weight involved.
Agricultural Chemicals
1. Agricultural chemicals can be dangerous. Always select the
correct chemical for the job. Improper usage of fertilizers,
fungicides, herbicides, insecticides, and pesticides could
cause injury to all living things.
2. Always read instructions supplied by the manufactures be-
fore opening chemical containers. Read and follow instructions supplied by the chemical manufacturer carefully
before each use.
3. Apply the same precautions when adjusting, servicing,
cleaning, or storing this implement as you would when putting chemicals into it.
4. Inform anyone who may come in contact with chemicals, or
an implement with chemicals, of any potential hazard or
safety precaution that should be observed.
5. Avoid inhaling smoke from any type of chemical fire.

Tire Pressure
Tire pressure should be checked regularly and maintained
as follows:
Transport/Ground Drive 9.5L X 15-8 ply.................. 44 psi
Contact Drive 13-6.50 X 6....................................... 40 psi
!
DANGER!
im and tire servicing can be dan-
erous. Explosive separation of a
tire and rim parts can cause serious injury or death.
o not attempt to mount a tire unless you
have the proper equipment and experience to perform the job.
This should only be done by persons properly trained and
equipped to do the job.
lways maintain the correct tire pressure. Do not inflate tires
above recommended pressure.
When inflating tires, use a clip-on air chuck and extension
hose long enough to allow you to stand to one side and not in
ront of or over tire assembly. Use a safety cage to enclose tire
and rim assembly when inflating.
nspect tires and wheels daily. Do not operate with low pressure, cuts, bubbles, damaged rims or missing lug bolts and
nuts.

Transporting
!
CAUTION!
The planter should never be transported faster than
20 miles per hour!
Before transporting the planter, check and practice the following items:
• The planter can be transported with full hoppers of seed.
It is best NOT to because the extra weight increases the
chances for problems on the road. Do not exceed 20
miles per hour.
• Check to see that the gauge tires on the planter have the
proper inflation, see the Tire Inflation Chart in “Section
10 Appendix” on page 62.
• Comply with all Federal, State and Local Safety Laws
when traveling on public roads.
• Remember, the planter is wider than the tractor and ex-
treme care must be taken to allow for safe clearance.
• Make sure the safety chain is properly attached with
enough slack in the chain to permit turning.
Leveling the Planter
IMPORTANT: For proper planter operation, it is important
that the planter frame be fully lowered into the correct
planting position. Achieving this position can be difficult
with some attachment combinations, especially when
planting in hard to penetrate soil conditions. If this situation is encountered, the following action may be warranted.
Reduce attachment down force levels. Avoid using more
attachment down force than is required.
Periodically check the planter to be certain the planting
units are running level.
Lower planter to planting position with the bottom of main
frame tube approximately 20 to 22 in. above level ground.
Refer to Figure 2-2.
When planting, the top of the hopper support panel should
be parallel to the ground.
Position tractor drawbar as required to obtain the proper
planter hitch height.

Rephasing the Hydraulic System
!
WARNING!
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.
Refer to Figure 2-3:
The lift system on your Great Plains Pull-Type Planter is a
master/slave system. All cylinders in the system are 2/way
cylinders. Rephasing the system is accomplished each
time the planter is lowered to the planting position. If un
level lifting occurs, lower the planter to the ground and hold
the remote lever momentarily. This time will allow oil to go
from the tractor to the master; bypass to the slave, then re
turn to the tractor.
If following this procedure does not level the planter, refer
“Section 7 Maintenance and Lubrication” on
to
page 45.

Planting Rates
Transmission Adjustment
Planting population changes are accomplished by setting
the sprocket transmission. By changing the combination
of sprockets the desired planting populations can be
achieved. For more information on this, refer to
Adjusting Planting Rates” on page 28.

The 15/28 tooth drive sprocket located on the inner side of
the contact drive wheel assembly will give you a 2 to 1
drive reduction, and will reduce the planter transmission
speed to reduce planting rates by approximately 1/2.
IMPORTANT: After each sprocket combination adjustment, make a field check to be sure you are planting at the
desired rate.
Contact Drive Wheel Spring Adjustment
There are two down pressure springs, see Figure 2-5, on
each contact drive wheel. The down pressure is factory
preset and should need no further adjustment.

Ridge Planting
Refer to Figure 2-8:
Lowering the wheel for ridge planting is accomplished by
inverting the cylinder mounting blocks.
To invert, first block under the frame to remove weight from
tires, remove the four 5/8” cap screws. Invert mounting
blocks and install cap screws. Torque per specifications,
“Section 10 Appendix” on page 62.

Tire Scraper (Optional)
Some soil types may require the use of the optional tire
scraper. The scraper prevents an excess of mud from
building up on lift tire that may hamper the contact drive
tire. Adjust the scraper so it does not contact the tire. See
Figure 2-7.

Marker Hydraulics
!
DANGER!
Never allow anyone near the planter when cycling the markers.
Excessive travel speed of the markers can be dangerous and/or
damage the marker assembly.The flow controls should be prop
erly adjusted before the marker assembly is first put into use.
The marker hydraulic system is equipped with needle
valves to control how fast each marker operates. The nee
dle valves are built into the sequence valve body. There
are two hex adjustment heads, one for controlling marker
speed up and one for controlling marker speed down. To
adjust the speed of each marker, loosen jam nut, screw
the needle valve clockwise to adjust the marker speed to a
low setting. Fold the marker up and down a few times and
recheck for pinching and kinking of hoses. With the tractor
engine at an operating rpm, adjust the needle valve to limit
the marker to a safe operating speed. Excessive folding
speeds can cause marker damage.
!
WARNING!
Escaping Fluid under pressure can have sufficient force to penetrate the skin. Check all hydraulic lines and houses 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
form 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.
General Notes
• If both markers are required down at the same time run
one marker down, momentarily start to raise it, reverse
the hydraulic lever and lower the opposite marker. Hold
ing the lever down then will force both markers down.
-
If the markers are down they can both be raised simultaneously but they can only be lowered one at a time alternating from one side to the other.
• When oil is cold, hydraulics operate slowly. Make sure
-
all adjustments are made with warm oil.
• On a tractor where the oil flow cannot be controlled, the
rate of flow of oil from the tractor may be greater than the
rate at which the marker cylinder can accept it. The trac
tor hydraulic control lever will have to be held until the
cylinder reaches the end of its stroke. This occurs most
often on tractors with an open center hydraulic system.
On tractors with a closed center hydraulic system, the
tractor’ s hydraulic flow control can be set so the tractor’s
detent will function properly.
Marker Transporting
Always transport the marker with it folded in the flat fold
position.
Liquid Fertilizer Attachment

WARNING!
Agricultural chemicals can be dangerous if not selected and
handled with care. Always read and follow directions supplied
by the chemical manufacturer.

Squeeze Pump
Specifications:
Maximum output per hose @ 125 rpm
5/16 Diameter hose-.58 GPM
1/2 Diameter hose-1.4 GPM
Maximum speed - 125 RPM
Maximum pressure - 5 PSI
Horsepower required per hose

1/2 Diameter hose - 0.05 HP
Pump Mounting and Hose Arrangement
The pump should always be mounted even with or lower
than the fertilizer tank and for accurate metering, the
speed should not exceed 125 RPM.
An important consideration for efficient operation of the
pump is the hose arrangement. If fewer than the standard
number of hoses are to be used, that is, using 4 or 5 hoses
on a 6 hose pump or 10 hoses on a 12 hose pump, the re
duction in the number of hoses may be made by:
1. Removing the hoses from near the center of the intake
manifold and capping the intake ports.

2. Running the unneeded hoses back into the solution
tank or tanks with the hoses still connected to the
pump.
!
CAUTION!
Avoid pressure when using the quick fill attachment. The rubber
plugs installed in the manifold may be forced out under pres
sure.
The discharge manifold must be in the forward position
when the pump is in operation. Squeeze Pumps are
shipped with the discharge manifold in the rearward or
non-operating position. To reposition the manifold, loosen
the wing nuts and slide the manifold forward and sideways
or rearward as required and retighten nuts. See
Figure 2-10.
-
Discharge Manifold Forward Position
Figure 2-10
Shut-off valves provided at various locations should be
closed to shut off flow when the planter sets overnight or
for extended periods of time. It is also important to close
the tank valves whenever service on the pump or hoses is
being performed. To prolong the life of the hoses in the
squeeze pump, the discharge manifold must be reposi
tioned to the rearward position when not in use to prevent
hose distortion. See
Figure 2-11.
