covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting
applicable local or state laws (if any). If a spark arrester is used, it should be maintained in effective working order by the operator.
In the State of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have
similar laws. Federal laws apply on federal lands. A spark arrester for the muffler is available through your nearest engine authorized

SECTION 1: IMPORTANT SAFE OPERATION PRACTICES

WARNING: THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF

NOT FOLLOWED, COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF
YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL
BEFORE ATTEMPTING TO OPERATE YOUR UNIT. WHEN YOU SEE THIS SYMBOL- HEED ITS
WARNING.

Danger: This cutting machine is capable of amputating hands and feet and throwing objects.

Failure to observe the following safety instructions could result in serious injury or death.

1. GENERAL OPERATION

• Read, understand, and follow all instructions in the
manual before attempting to attach and operate
your tiller. Keep this manual in a safe place for
future reference and for ordering replacement
parts.

• Only allow responsible adults familiar with both the
tiller and tractor instructions to operate the
machine. Know controls and how to stop the
machine quickly.

• Do not put hands or feet under or near rotating
parts. Keep clear of tiller tines at all times.

• Clear the area of objects such as rocks, toys, wire,
etc. which could become caught in the tiller tines.
Always wear safety glasses or eye shields during
operation or while performing an adjustment or
repair, to protect eyes from foreign objects.

• Be sure the area is clear of other people and pets
before tilling. Stop machine if anyone enters area.

• Never carry passengers. Only the operator should
ride on the unit and only ride in the seat.

• Disengage tiller before shifting into reverse and
backing up. Always look down and behind before
and while backing.

• Slow down before turning. Operate the tractor
smoothly. Avoid erratic operation and excessive
speed.

• Never leave a running machine unattended.
Always disengage attachment, place transmission
in neutral, set park brake, stop engine and remove
key before dismounting.

• Raise and disengage tiller before making sharp
turns. Leaving tiller lowered and engage may
adversely offset steering/control of machine.

• Disengage tiller when not tilling.

• Stop engine and wait until tiller comes to a
complete stop before making any repairs,
adjusting or removing any rocks or debris.

• Till only in good daylight or good artificial light.

• Do not operate the machine while under the
influence of alcohol or drugs.

• Watch for traffic when operating near or crossing
roadways.

• Use extra care when loading or unloading the
machine into a trailer or truck. This unit should not
be driven up or down a ramp onto a trailer or truck
under power, because the unit could tip over,
causing serious personal injury. The unit must be
pushed manually to load or unload properly.

• Wear sturdy, rough-soled work shoes and close­fitting slacks and shirts. Do not wear loose fitting
clothes or jewelry. They can be caught in moving
parts. Never operate a unit in bare feet, sandals, or
sneakers.

• Check overhead clearance carefully before driving
under power lines, wires, bridges or low hanging
tree branches, before entering or leaving buildings,
or in any other situation where the operator may
be struck or pulled from the unit, which could result
in serious injury.

• Disengage all attachment clutches, thoroughly
depress the brake pedal, and shift into neutral
before attempting to start engine.

2. Slope Operation

• Slopes are a major factor related to loss of control
and tip-over accidents which can result in severe
injury or death. All slopes require extra caution. If
you cannot back up the slope or if you feel uneasy
on it, do not till on it.

DO:

• Till up and down slopes, not across.

• Remove obstacles such as rocks, limbs, etc.

• Watch for holes, ruts, bumps, and objects hidden
under the soil (e.g. rocks). Uneven terrain could
overturn the machine.

• Use slow speed. Choose a low enough gear so
that you will not have to stop or shift while on the
slope. Always keep tractor in gear when going
down slopes to take advantage of engine braking
action.

2

• Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed or
direction. Rapid engagement or braking could
cause the front of the machine to lift.

• Avoid starting or stopping on a slope. If tires loose
traction, disengage tiller and proceed slowly
straight down the slope.

• For your safety, use the slope gauge included as
part of this manual to measure slopes before
operating this unit on a sloped or hilly area. If the
slope is greater than 15 degrees as shown on the
slope gauge, do not operate this unit on that area
or serious injury could result.

DO NOT:

• Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.

• Do not operate unit near drop-offs, ditches or
embankments. A wheel over the edge or an edge
caving in could cause sudden overturn.

• Do not operate tractor on wet grass. Reduced
traction could cause sliding.

• Do not try to stabilize the machine by putting your
foot on the ground.

3. Children

• Tragic accidents can occur if the operator is not
alert to the presence of children. Children are often
attracted to the machine and the tilling activity.
Never assume that children will remain where you
last saw them.

• Keep children out of the tilling area and in watchful
care of an adult other than the operator.

• Be alert and turn machine off if children enter the
area.

• Before and when backing, look behind and down
for small children.

• Never carry children. They may fall off and be
seriously injured or interfere with the safe machine
operation.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
vision.

4. Service

• Use extra care in handling gasoline and other
fuels. They are flammable and vapors are
explosive.

• Use only an approved container.

• Never remove gas cap or add fuel with the engine
running. Allow engine to cool at least two minutes
before refueling. Do not smoke.

• Never refuel the machine indoors.

• Never store the machine or fuel container inside
where there is an open flame, or spark, such as a
water heater, space heater, clothes dryer and the
like.

• Never run a machine inside a closed area.

• Check frequently and keep nuts and bolts tight and
keep equipment in safe working condition.

• Never tamper with safety devices. Check their
proper operation regularly. Use all guards as
instructed in this manual.

• To reduce fire hazard, keep machine free of grass,
leaves or other debris build-up. Clean up oil or fuel
spillage. Allow machine to cool before storing.

• Stop and inspect the equipment for damage if you
strike an object (e.g. rock). Repair, if necessary,
before re-starting and operating the machine.

• Never make adjustments or repairs with the engine
running.

• Check brake operation frequently. Adjust and
service as required.

• Muffler, engine, and belt guards become hot
during operation and can cause a burn. Allow to
cool down before touching.

• Do not change the engine governor settings or
overspeed the engine.

Danger: Your unit was built to be operated according to the rules for safe operation in this

manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. If you violate any of these rules, you may cause serious injury to yourself or
others.
