Important Safety Information
Great Plains Mfg., Inc.
Use Safety
Lights and Devices
Slow-moving tractors, self-propelled
equipment 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.
Transport
Machinery Safely
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 ke y before performing
maintenance.
▲ Allow implement to cool completely.
▲ 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.

Important Safety Information
Prepare for Emergencies
▲ Be prepared if a fire starts.
▲ Keep a first aid kit and fire extin-
guisher handy.
▲ Keep emergency numbers for
doctor, ambulance, hospital and
fire department near phone.
911
Wear
Protective Equipment
▲ Wear protective clothing and
equipment.
▲ Wear clothing and equipment
appropriate for the job. Avoid
loose-fitting clothing.
▲ Because prolonged exposure to
loud noise can cause hearing
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 5. 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 tight, caus-
ing 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.

Description of Unit
The 6- and 8-row , pull-type planter is a to wed planting implement. The frame consists of 7-by-7-inch tubing. Planting rates are adjustable by changing sproc k ets 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

Row Unit Operation
Never back up with row units in ground. If you do , check all
openers to be sure none are clogged. Always lift planter
out of ground when turning at row ends and for other
short-radius turns.
For information on planting-depth and down-pressure
adjustments, refer to Row Unit Adjustments , “Adjust
ments,” beginning on page 28.
Chemical Hoppers
The optional chemical hopper comes in two versions: one
chemical meter or two chemical meters with a divider that
separates the hopper into two compartments.
Before filling chemical hoppers, clean any f oreign objects
out of hoppers. To remove hopper from row unit, disen
gage meter clutch and undo over-center latch at front of
hopper. See
Set and calibrate chemical-application rate as explained
under Granular Chemical Rates, “Adjustments,”
Fill chemical hoppers and replace hopper lids before operating planter.
Periodically clean dirt and foreign objects out of chemical
hoppers.

Marker Operation
Markers can be raised simultaneously but must be lo wered 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 h ydraulic le v er and lower the opposite
marker. Holding the lever down will force both markers
down.
On a tractor where the oil flow cannot be controlled, the
rate of flow of oil from the tractor may be g reater than the
rate at which the marker cylinder can accept it. The tractor
hydraulic control le ver 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.
Liquid Fertilizer Operation
!
WARNING!
Agricultural chemicals can be dangerous if not selected and
handled with care. Always read and follow directions supplied
by the chemical manufacturer.
For accurate metering, keep pump speed below 125 rpm.
To operate the pump, the discharge manif old must be in
the forward position as shown in
shipped in the rearward position.
To position the manifold forw ard for operation, loosen the
wing nuts on the manifold and pull the manif old forward.

ties,” page 53, and Hitching Planter to Tractor, “Prep-
aration and Setup,” page 11.
2. Unload hoppers before transporting if at all possible.
The planter can be transported with full hoppers, but
the added weight will increase stopping distance and
decrease maneuverability.
3. Check that tires are properly inflated. Refer to Tire
Inflation Chart, “Appendix,”
4. Comply with all federal, state and local laws when
traveling on pub lic roads .
5. Remember that the planter is wider than the tractor.
Allow safe clearance .
6. Transport slowly over uneven or rough terrain.

Parking
See also Storage, “Maintenance and Lubrication,”
page 43, for information on long-term storage.
1. Park planter on a lev el, solid area.
2. Place jack on stob on the side of the planter tongue.
Lower jack until weight of planter is off of tractor dr aw
bar. Remove hitch pin and safety chain.
3. Disconnect any hydraulic hoses from tractor. Do not
let hose ends rest on the ground.

Transporting
!
WARNING!
Towing the planter at high speeds can lead to loss of vehicle
control. Loss of vehicle control can lead to serious road acci
dents, injury and death. Do not exceed 20 mph.
Before transporting the planter, chec k and practice the following items.
1. Check that planter is securely hitched to a sufficient
tractor. Alw ays use a locking-style hitch pin sized to
match holes in hitch and drawbar (minimum 1-inch-di
ameter, heat-treated pin). Attach saf ety chain to tr actor with enough slack to permit turning. Refer to
