Important Safety Information
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. The signal words are:
!
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!

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 key 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.

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 tight, caus-
ing towed implements to ride up
on wheels.
▲ Never stand on or use tires as a
step. Tires not in contact with the
ground will rotate easily.
▲ Keep bystanders well away when
folding markers. Falling or folding
markers can crush bystanders.
Tire Safety
Tire maintenance can be dangerous
and should be performed by trained
personnel using correct equipment.
▲ Inflate tires to proper pressure
and torque wheel bolts as recommended in “Appendix,” page 34.
▲ 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.

Hitching Tractor to Drill
!
DANGER
You may be severely injured or killed by being crushed between
the tractor and drill. Do not stand or place any part of your
body between drill and moving tractor. Stop tractor engine and
set park brake before installing pins.
1. Raise or lower tractor three-point arms as needed and
pin lower arms to drill.
2. Pin upper arm to drill. For category III tractors, install
hitch pin in the lower hole. For category IV-N tractors,
install hitch pin in the upper hole.
3. Slowly raise drill. Watch for cab interference.
4. If using optional parking stands, unpin stand tubes.
Rotate stands up into field position and repin. See Figure 1-1.
5. Adjust top three-point link so that top edge of drill box
is parallel with ground when drilling.
NOTE: Do not use link to adjust opener depth. For opener
adjustments, refer to Opener Down Pressure and Opener
Depth, “Adjustments,” starting on page 15.
6. Set your tractor three-point-draft control to float position.
7. Plug lead from drill light harness into tractor receptacle.
Hydraulic Hookup
!
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.
Great Plains hydraulic hoses are coded to help you hookup to your tractor outlets. To distinguish hoses on the
same hydraulic circuit, refer to plastic hose holder. See
Figure 1-2. Connect hose under extended cylinder to outlet you choose for cylinder extension. Connect hose under
retracted symbol to outlet for cylinder retraction.
