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.
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 indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe practices.
Prepare for Emergencies
▲ Be prepared if a fire starts
▲ Keep a first aid kit and fire extinguisher handy.
▲ Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals” on page 5, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.

2 3323-4336DH Table of Contents Index Great Plains Manufacturing, Inc.
Use Safety Chains
▲ Use safety chains to help control drawn machinery should it
separate from tractor draw-bar or trailing nurse tank hitch.
▲ Use chain with a strength rating equal to or greater than
the gross weight of towed machinery.
▲ Attach implement chain to tractor draw-bar support or
specified anchor location. Allow only enough slack in chain
for turns.
▲ Replace chain if any links or end fittings are broken,
stretched or damaged.
▲ Do not use safety chain for towing.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury. This Disk Harrow requires a
Power-Beyond port, which is always under pressure
when the tractor is running.
▲ Avoid the hazard by relieving pressure at other remote, and
shutting down tractor before connecting, disconnecting or
inspecting hydraulic lines.
▲ Use a piece of paper or cardboard, 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, seek immediate medical assistance
from a physician familiar with this type of injury.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
▲ Never allow children to operate equipment.
▲ Keep all bystanders away from machine during operation.
Use Safety Lights and Devices
Slow-moving tractors 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 driv-
ing on public roads.
▲ Use lights and devices provided with implement.

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Transport Machinery Safely
Maximum transport speed for implement is 20 mph (32
kph), 13 mph (22 kph) in turns. Some rough terrains
require a slower speed. Sudden braking can cause a
towed load to swerve and upset.
▲ Do not tow an implement or nurse tank that weighs more
than 1.5 times the weight of towing vehicle.
▲ Carry reflectors or flags to mark Disk Harrow in case of
breakdown on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“DH Specifications and Capacities” on page 32.
▲ 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.
▲ Reduce speed on rough roads.
▲ Comply with national, regional and local laws.
▲ Do not fold or unfold the Disk Harrow while the tractor is
moving.
Shutdown and Storage
▲ Lower Disk Harrow, put tractor in park, turn off engine,
and remove the key.
▲ Secure Disk Harrow using parking jack provided.
▲ Detach and store Disk Harrow in an area where children
normally do not play.
Tire Safety
Tire changing can be dangerous. Employ trained personnel using correct tools and equipment.
▲ When inflating tires, use a clip-on chuck and extension hose
long enough for 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.

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, put tractor in park, turn off engine, and
remove key before performing maintenance.
▲ Make sure all moving parts have stopped and all system
pressure is relieved.
▲ Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on Disk
Harrow.
▲ 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.
Safety At All Times
Thoroughly read and understand the instructions in this
manual before operation. Read all instructions noted on
the safety decals.
▲ Be familiar with all Disk Harrow functions.
▲ Operate machinery from the driver’s seat only.
▲ Do not leave Disk Harrow unattended with tractor engine
running.
▲ Do not stand between tractor and implement, or implement
and nurse tank, during hitching.
▲ Keep hands, feet and clothing away from power-driven
parts.
▲ Wear snug-fitting clothing to avoid entanglement with mov-
ing parts.
▲ Watch out for wires, trees, etc., when folding and raising
Disk Harrow. Make sure all persons are clear of working
