result in serious injury. This tiller is capable of amputating hands and feet. Failure to observe the
following safety instructions could result in serious injury or death.
1. GENERAL OPERATION
• Read this operator’s manual carefully in its entirety
• Do not place feet or hands on or near the tines
when starting the engine or while the engine is
running.
before attempting to assemble this machine. Read,
understand, and follow all instructions on the
machine and in the manual(s) before operation. Be
completely familiar with the controls and the proper
use of the machine before operating it. Keep this
manual in a safe place for future and regular
reference and for ordering replacement parts.
• Never attempt to make depth bar, tine width, cable,
handle, or wheel adjustments while the engine is
running.
• Do not leave the tiller unattended with the engine
running.
• Your tiller is a powerful tool, not a plaything.
Therefore, exercise extreme caution at all times.
Your unit has been designed to perform one job: to
till soil. Do not use it for any other purpose.
• Before attempting to remove rocks, bricks and
other objects from tines, stop the engine and be
sure the tines have stopped completely. Disconnect
the spark plug wire and move it away from the
spark plug.
• Never allow children under age 14 to operate the
unit. Children 14 years and older should only
operate the unit under close parental supervision.
Only responsible individuals who are familiar with
these rules of safe operation should be allowed to
use your unit.
• If your machine should start making an unusual
noise or vibration, immediately stop the engine and
allow the machine to come to a complete stop.
Disconnect the spark plug wire and move it away
from the spark plug. Take the following steps:
• Do not operate tiller while under the influence of
alcohol or drugs.
•
•
•
Inspect for damage.
Repair or replace any damaged parts.
• Keep the area of operation clear of all persons,
particularly small children and pets. Stop the
engine when they are in the vicinity of your tiller.
Check for any loose parts and tighten to
assure continued safe operation.
• Wear sturdy, rough-soled work shoes and close
fitting slacks and shirt. Shirt and slacks that cover
the arms and legs and steel-toed shoes are
recommended. Do not wear loose fitting clothes or
jewelry and secure hair so it is above shoulder
length. They can be caught in moving parts. Never
operate a unit in bare feet, sandals or sneakers.
• Muffler and engine become hot and can cause a
burn. Do not touch.
• Keep all shields, guards and safety devices in
place and operating properly.
• Use caution when tilling near fences, buildings and
underground utilities. Rotating tines can cause
damage or injury.
• Operate tiller only in daylight or good artificial light.
• Do not operate engine if air cleaner or cover over
carburetor air intake is removed, except for
adjustment. Removal of such parts could create a
fire hazard.
• Do not start tiller unless the shift lever (if provided)
is in the neutral (N) position.
• Do not allow anyone to stand or walk in front of
tiller when starting or running engine.
3
• Only use accessories approved for this machine by
the manufacturer. Read, understand, and follow all
instructions provided with the approved accessory.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Never refuel unit indoors because flammable
vapors will accumulate in the area.
• If situations occur which are not covered by this
manual, use care and good judgment. Contact your
dealer for assistance.
• Never store the machine or fuel container inside
where there is an open flame or spark such as a
gas hot water heater, space heater, clothes dryer
or furnace.
2. CHILDREN
• Tragic accidents can occur if the operator is not
alert to the presence of small children. Children are
often attracted to the tilling activity. Never assume
that children will remain where you last saw them.
• Never run your machine in an enclosed area as the
exhaust from the engine contains carbon
monoxide, which is a odorless, tasteless and
deadly poisonous gas.
• Keep children out of the work area and under the
watchful eye of a responsible adult other than the
operator.
• To reduce fire hazard, keep engine and muffler free
of leaves, grass, and other debris build-up. Clean
up fuel and oil spillage. Allow unit to cool at least 5
minutes before storing.
• Be alert and turn the unit off if a child enters the
area.
• Before cleaning, repairing, or inspecting, make
certain the tines and all moving parts have stopped.
Disconnect the spark plug wire and keep wire away
from spark plug to prevent accidental starting. Do
not use flammable solutions to clean air filter.
• Never allow children under the age of 14 to operate
the tiller.
3. SERVICE
• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
• Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
• Never tamper with safety devices. Check their
proper operation regularly.
• Store fuel and oil in approved containers, away
from heat and open flame, and out of the reach of
children. Check and add fuel before starting the
engine. Never remove gas cap or add fuel while the
engine is running. Allow engine to cool at least two
minutes before refueling.
• Do not alter or tamper with the engine’s governor
setting. The governor controls the maximum safe
operating speed of the engine. Overspeeding the
engine is dangerous and will cause damage to the
engine and to other moving parts of the machine.
• Replace gasoline cap securely and wipe off any
spilled gasoline before starting the engine as it may
cause a fire or explosion.
WARNING — YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who

HANDLE ADJUSTMENT
BELT TENSION ADJUSTMENT
The handle height may be adjusted. Refer to the
Control section for details of handle adjustment.
Periodic adjustment of the belt tension may be
required due to normal stretch and wear on the belt.
Adjustment is needed if the tines or wheels seem to
hesitate while turning, but the engine maintains the
same speed.
10
To adjust the tension on the belt, refer to clutch
adjustment information in “Checking the Clutch
Adjustment” section of the Assembly Instructions.
After belt tension has been adjusted, if the belt is
excessively stretched, you may need to adjust the
idler pulley rod. This can easily be checked. With the
engine off and the clutch control bail disengaged,
shift the gear selection handle to each forward
mode. If the indicator bracket touches the idler pulley
rod, (with the clutch control bail disengaged), then
an adjustment is necessary.
5. Replace the wave washer and hairpin clip.
6. Check clearance of the idler pulley rod to the
indicator bracket by shifting to each forward
mode, as before.
CARBURETOR ADJUSTMENT
WARNING: If any adjustments are
made to the engine while the engine is
running, (e.g. carburetor), disengage all
clutches and tines. Keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
1. Disconnect and ground out spark plug wire
against the engine.
2. Remove the belt cover as described in the belt
replacement section on page 12.
Never make unnecessary adjustments. The factory
settings are correct for most applications. If
adjustments are needed, refer to the separate
engine manual packed with your tiller.
3. Remove the hairpin clip and flat washer from the
idler pulley rod. See Figure 12.
4. Move the idler pulley rod to the lower hole in the
idler bracket. See Figure 12.
SECTION 10: LUBRICATION
Transmission—The transmission is pre-lubricated
and sealed at the factory. It requires no checking
unless the transmission is disassembled. To fill with
grease, lay the right half of the transmission on its
side. Add 30 ounces of Benalene 920 grease. Apply
a bead of RTV or silicone sealant to the right half of
the transmission, all the way around the gear
compartment. Assemble the left half to it. This
grease can be obtained at your nearest authorized
dealer. Order part number 737-0300.
Clutch Bail—Lubricate the pivot point on the clutch
bail and the cable at least once a season with light
oil. The control must operate freely in both
directions.
Pivot Points—Lubricate all pivot points and linkages
at least once a season with light oil.
Tine Shaft—Remove tines at least once a season
and lubricate with oil.
Wheel Axle—Remove the wheel assemblies at least
once a season and lubricate with oil.
SECTION 11: MAINTENANCE
replacement is recommended at the start of each
tiller season; check engine manual for correct plug
type and gap specification.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area)
clean to permit proper air circulation which is
essential to engine performance and life. Be certain
to remove all dirt and combustible debris from
muffler area.
WARNING: Disconnect the spark plug
wire and ground it against the engine
