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 machinery should
it separate from the tractor drawbar.
Use a chain with the strength rating equal to or greater
than the gross weight of the towed machinery.
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 safe-
ty chain for tow-
ing.
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

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.

Introduction
Introduction
Great Plains Mfg., Inc.
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 ma
-
chine.
Description of Unit
The 6- and 8-row, pull-type planter is a towed seeding implement. The frame consists of 7-by-7-inch tubing. Planting rates are adjustable by changing sprockets on the
planter transmission or contact drive. Row units are
mounted on the frame. Seed hoppers are standard on the
row units; chemical hoppers and granular-chemical appli
cators are available. Springs on each row unit provide
down pressure needed for the double-disk openers to
make a seed trench. Finger-pickup meters singulate and
dispense seed from the hopper and deliver it to the trench.
Seeding depth is controlled by side gauge wheels on the
openers. Closing wheels or disks close the trench. With an
optional 5-by-7-inch fertilizer bar, the planter can be outfit
ted with dry or liquid fertilizer application and tillage attachments.
Intended Usage
Use this implement for seeding row crops in large fields.
Tow the implement behind an agricultural tractor at plant
ing speed of 5 mph and at transport speeds of less than 20
mph. The unit is designed for conventionally tilled fields
but can be used in no- or minimum-till conditions if outfit
ted with optional tillage attachments.

Basic Planting Operation
For the best planting results:
• plant at 5 mph,
• maintain tire pressure in the gauge tires and
• replace worn meter parts.
Rephasing the Hydraulic System
The hydraulic lift system on your Great Plains pull-type
planter is a master-and-slave system. All cylinders in the
system are two way. Each time the planter is lowered into
planting position, the system is rephased.
If unlevel lifting occurs, lower the planter to the ground and
hold the remote lever momentarily.
If following this procedure does not level planter lifting, refer to “Section 5 Maintenance and Lubrication” on
page 35.
Seed Meter and Hopper Operation
This planter is equipped with a 12-finger mechanical corn
meter.
To disengage the seed-meter or chemical-hopper clutch,
pull the knob and rotate 90 degrees clockwise or counterclockwise until the roll pin aligns with the notch in the end
of the drive hub. Release knob. See
To engage, pull and rotate the knob until the shaft aligns
with the drive hub, then release.

Squeeze Pump Hose Alignment
Refer to Figure 2-6.
If end hoses (A and B) should run off the back, re-align
hoses as follows:
1. On hose A, loosen hose clamps on intake manifold
and twist hose counter-clockwise 1/4 turn.
2. On hose B, loosen hose clamp on intake manifold and
twist hose clockwise 1/4 turn.
3. Retighten hose clamp.
Transporting
!
CAUTION!
Never transport the planter 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 in
creases the chances for problems on the road.
• Check that the gauge-wheel tires are properly inflated
as listed on the Tire Inflation Chart,
page 52.
• Comply with all federal, state and local safety laws
when traveling on public roads.
• Remember, the planter is wider than the tractor and
extreme care must be taken to allow for safe clear
ance.
• Make sure the safety chain is properly attached with
enough slack in the chain to permit turning.
• Always transport the marker with it folded in the flat
fold position.

CAUTION!
Avoid pressure when using the quick-fill attachment. The rubber
plugs installed in the manifold may be forced out under pressure.

Marker Operation
Markers can be raised simultaneously but can only be lowered one at a time. 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. Holding the lever down then will force both mark
ers down.
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 tractor
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.

3. Loosen the carriage bolt and flange nut on the idler
plate. Rotate the idler plate to move the idlers out of
the chain.
4. Remove the chain. Remove sprockets currently on
transmission shafts.
5. Find the correct sprockets on the storage brackets
and place on the transmission shafts.
NOTE: When not in use, store all extra sprockets on the
storage bracket.
6. Place the sprockets on the drive/driven shafts.
7. Re-route chain over idlers and sprockets.
8. Turn the idler plate counter-clockwise to take up chain
slack. Chain should have a maximum of 1/4-inch
slack.
9. Retighten the carriage bolt and flange nut to secure
idler plate.
10. Replace the transmission cover and hand tighten the
knob.
2-to-1 Drive Reduction
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 reduce planting rates by about onehalf.
NOTE: After each sprocket combination adjustment, make
a field check to be sure you are planting at the desired
rate.

Checking Planting Population
After setting the transmission or contact-drive reduction,
always field check the planting population as follows.
1. Release spring pressure on opener disks and wheels.
2. Tie up closing disks and wheels to hopper support using a chain or heavy wire. Pin up optional Seed-Lok
wheels
3. Adjust the planting depth to a shallow setting.
4. Plant at a normal speed for a short distance.
5. For 30-inch rows, measure 17 feet 6 inches (one-thousandth of an acre.)
6. Count the number of seeds in one row over the measured distance.
7. Multiply the number of seeds counted by 1000. This
gives you total population.
Example
• 30-inch row spacing
• Measure 17 feet 6 inches
• 24 seeds over measured distance in one row
24 X1000 = 24,000 plant population per acre
If the planting population is significantly different than desired, make the following checks.
• Double check the sprocket combination in the transmission. Refer to the “Planting Rates for Finger
Pickup Corn Meters” on page 16.
• Check air pressure in the gauge-wheel tires. Refer to
Tire Inflation Chart,
• Check for meter malfunction or excessive contactdrive-wheel slippage. Refer to
shooting” on page 32.
