Be Aware of Signal Words
Signal words designate a degree or lev el 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 f or 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 ma y also be
used to alert against unsafe practices.
CAUTION indicates a potentially hazardous situation which, if not avoided, ma y result in minor or
moderate injury . It may also be used to alert

Be Familiar with Safety Decals
▲ Read and understand “Safety Decals,”page 7,
thoroughly.
▲ Read all instructions noted on the decals.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could
be struck by foreign objects or thro wn from the
machine.
▲ Never allow children to operate equipment.
▲ Keep all bystanders away from machine dur-
ing operation.
Shutdown and Storage
▲ Lower implement, put tractor in park, turn off
engine, and remove the key.
▲ Secure implement using blocks and supports
provided.
▲ Detach and store implement in an area where
children normally do not play.
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 driving on public roads.
▲ Use lights and devices provided with imple-
ment.

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.
▲ Carry reflectors or flags to mark implement in
case of breakdown on the road.
▲ Keep clear of overhead power lines and other
obstructions when transporting.
Important Safety Information
3
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the
skin, causing serious injury.
▲ Avoid the hazard by relieving pressure before
disconnecting 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, see a doctor immedi-
ately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene may result.

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 the 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.
▲ Allow implement to cool completely.
▲ Disconnect battery ground cable (-) before
servicing or adjusting electrical systems or
before welding on implement.
▲ 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.
Prepare for Emergencies
▲ Be prepared if a fire starts.
▲ Keep a first aid kit and fire extinguisher handy.
OFF
▲ Keep emergency numbers for doctor, ambu-
lance, hospital and fire department near
phone.
Wear Pr otective 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.

Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use can seriously injure persons, animals,
plants, soil and property .
▲ Read and follow chemical manufacturer’s
instructions.
▲ Wear protective clothing.
▲ Handle all chemicals with care.
▲ Avoid inhaling smoke from any type of chemi-
cal fire.
▲ Store or dispose of unused chemicals as
specified by chemical manufacturer.
Use A Safety Chain
▲ Use a safety chain to help control drawn
machinery should it separate from tractor
drawbar.
Important Safety Information
5
▲ Use a chain with a strength rating 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.
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 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.

ment during hitching.
▲ Keep hands, feet and clothing away from
power-driven parts.
▲ Wear snug-fitting clothing to avoid entangle-
ment with moving parts.
▲ Watch out for wires, trees, etc., raising imple-
ment. Make sure all persons are clear of working area.
