RULES AND INSTRUCTIONS

CAREFULLY

Warning:

This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forestcovered, 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
service dealer or contact the service department, P.O. Box 361131 Cleveland, Ohio 44136-0019.

UsingYourTiller
Your tiller (also known as a cultivator) is a precision
built machine designed for seed bed preparation,
cultivating, furrowing and mulching. It is engineered to
minimize the hardest work in the vegetable or flower
garden, to till the soil for planting and cultivating, and to
perform many other useful labor saving tasks in the
garden.

WheelPosition
The tiller is shipped with the wheels adjusted such that
the unit sits level. While tilling, as the tines enter the
ground and the front of the tiller lowers, the wheels
must be raised to level the unit, which is essential for
proper engine operation. This adjustment is made by
removing the clevis pin and hairpin clip from wheel
yoke, raising the wheels to the desired height, and
replacing the clevis pin and hairpin clip. See Figure 5.

& Clevis Pins

Figure 5

ControllingSpeedAndTillingDepth
WheelYokeAdjustment
Place wheel yoke so that the wheels are forward
(nearest point between wheels and tines) for shallow
tilling, cultivating and transport. The forward speed will
increase. Turn yoke around (farthest point between
wheels and tines) for deep tilling. Forward speed will
decrease. See Figure 6.

DepthStake Adjustment
The depth stake acts as a brake for the tiller and
controls the depth and speed at which the machine will
operate. Remove the clevis pin and hairpin clip to raise
or lower depth stake. Refer to Figure 5.
By increasing the depth of the depth stake, the forward
speed of the machine is reduced and the working depth
is increased. When the depth stake is raised, the
working depth of the machine is reduced and the
forward speed is increased. The working depth of the
machine may be predetermined by setting the depth
stake and wheels so that the wheels are about four
inches from the ground when the tines and depth stake
are resting on the ground. This setting will permit a
working depth of about four inches. When presetting
the working depth, the handles should be adjusted so
the hand grips are a little above waist. The tiller will be
lower when the tines and depth stake penetrate the
ground. See Figure 7.
Transport Depth Stake
Position

Shallow
Tilling_

When tilling, leave approximately 8 inches of untilled
soil between the first and second tilling paths, then
make the third path between the first and second. In
some soils, the desired depth is obtained the first time
over the garden. In other soils, the desired depth is
obtained by going over the garden two or three times. In
the latter case, the depth stake should be lowered
before each succeeding pass over the garden. Passes
should be made across the length and width of the
garden alternately. Rocks which are turned up should
be removed from the garden area. See Figure 8.

Deep

Deep Tilling
Figure 7

Figure 8
Handle Pressure
Further control of tilling depth and travel speed can be
obtained by variation of pressure on the handles.
•
A downward pressure on the handles will reduce
the working depth and increase the forward speed.
•
An upward pressure on the handles will increase
the working depth and reduce the forward speed.
The type of soil and working conditions will determine
the actual setting of the depth stake and the handle
pressure required.
Transportingthe Tiller
•
To transport the tiller to or from the garden, pivot
the depth stake forward and out of the way. With
the throttle control in SLOW position, the unit will
walk freely on the lawn. If the operator does not
allow the tiller to move freely, the unit will start to till
the surface. Refer to Figure 7.
Cultivating
For cultivating, a two to three inch depth is desirable.
Setting the wheels and depth stake so that the wheels
are about two inches above the ground while the tiller is
resting on the tines and depth stake will allow the
machine to work at cultivating depth. The throttle
should be set to control forward movement to a slow
walking speed. With the outer tines installed, the
working width of the machine is 22 or 24 inches.

Figure 9

The tiller has many uses other than tilling and
cultivating a garden. One of these is the preparation of
lawn area for seeding. The tiller will prepare a deep
seed bed which will be free of hard untilled spots,
allowing a better stand of grass to grow. The tiller is
very useful for loosening hard soil for excavation with a
shovel. No tedious handwork will be necessary. Your
tiller may be used for mixing compost in the pile, or for
mixing it with the soil in your garden. This should be
done after the soil has been broken to the full working
depth. The compost should be worked in to a depth of
six to seven inches. This may be done by working the
length of the garden and then by making separate
passes across its width. The addition of decayed
organic matter will substantially increase the fertility of
your garden. For proper decaying action, fertilizer
should be applied and worked in with the mulch
materials. Breaking up leaves and straw and mixing it
with several inches of soil causes the soil to hold
moisture longer and allows proper aeration of the plant
root system. This also retards the growth of weeds.

The tilling width of the unit is 22 inches. Tilling width can
be increased to 24 inches by removing the clevis pins

Clean the underside of the tine shield after each use.
The dirt washes off the tines easier if rinsed off
immediately instead of after it dries. Always towel dry
the tiller afterwards and apply a light coat of oil or
silicone to prevent rusting or water damage.

Engine
Refer to the separate engine manual for engine
maintenance instructions.

IMPORTANT:Never use a "pressure washer" to clean
your tiller. Water can penetrate tight areas of the tiller
and its chain case and cause serious damage to the
unit.

Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.

BeltReplacement

Service air cleaner every ten hours under normal
conditions. Clean every hour under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be
serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.

Your tiller has been engineered with a belt made of
special material (Kevlar Tensile) for longer life and
better performance. It should not be replaced with an
off-the-shelf belt. Order all belts through your
authorized service dealer.

IMPORTANT: Never run your engine without air cleaner
completely assembled.

Disconnect and ground spark plug wire against the
engine.
Remove the two hex washer screws from the front
of the belt cover and remove the lock nut and flat
washer from the side of the belt cover.

The spark plug should be cleaned and the gap reset
every 25 hours of engine operation. Spark plug
replacement is recommended at the start of each tiller
season; check engine manual for correct plug type and
gap specification.

Remove the belt cover. See Figure 11.
Belt Cover

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.

Off-SeasonStorage

Refer to the engine manual for correct engine
storage instructions.
Wipe tines with oiled rag to prevent rust.
Store tiller in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.

NOTE:

When storing any type of power equipment in
an unventilated or metal storage shed, care should be
taken to rustproof the equipment. Using a light oil or
silicone, coat the equipment and especially any
springs, bearings, and cables.

If the tiller will not be used for a period longer than 30
days, the following steps should be taken to prepare the
tiller for storage.
•

Clean the exterior of engine and the entire tiller
thoroughly. Lubricate the tiller as described in the
lubrication instructions.

•

We do not recommend the use of pressure
washers to clean your unit. They may cause
damage to spindles, pulleys, bearings or the
engine. The use of pressure washers will result in
shortened life and reduce serviceability.
