OPERATION
The operation of any tiller can result in foreign objects thrown into the eyes, which can result
in severe eye damage. Always wear safety glasses or eye shields before starting your tiller
and while tilling. We recommend a wide vision safety mask for over spectacles or standard
safety glasses.
HOW TO USEYOUR TILLER
Know how to operate all controls before adding fuel and
oil or attempting to start engine.
TILLING
The speed and depth of tilling is regulated by the position
of the depth stake and wheel height.
The depth stake should always be below the wheels for
digging. It serves as a brake to slow the tiller’s forward
motion to enable the tines to penetrate the ground. Also,
the more the depth stake is lowered into the ground the
deeper the tines will dig.

OPERATION
WARNING: Experienceindicatesthatalcoholblendedfuels
TO TRANSPORT
(called gasohol or using ethanol or methanol) can attract
moisture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system of
an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of
30 days or longer. Drain the gas tank, start the engine
and let it run until the fuel lines and carburetor are empty.
Use fresh fuel next season. See Storage section of this
manual for additional information. Never use engine or
carburetor cleaner products in the fuel tank or permanent
damage may occur.
CAUTION: Beforeliftingortransporting,

Fill engine with oil to point of overflowing. For approx-
imatecapacitysee“PRODUCTSPECIFICATIONS”on
page 3 of this manual.
When starting engine for the first time or if engine has run
out of fuel, it will take extra pulls of the recoil starter to
move fuel from the tank to the engine.
•
•
Tilt tiller back on its wheels and then re-level.
With engine level, refill to point of overflowing if nec-
essary. Replace oil filler plug.
•
•
•

tilled between passes. Then go back between tilled
rows. (See Fig. 9) There are two reasons for doing
this.First, wide turns are much easier to negotiate than
about-faces. Second, the tiller won’t be pulling itself,
and you, toward the row next to it.

CULTIVATING
CAUTION: Until you are accustomed
Cultivating is destroying the weeds between rows to pre-
vent them from robbing nourishment and moisture from the
plants. At the same time, breaking up the upper layer of
soil crust will help retain moisture in the soil. Best digging
depth is 1"-3".
to handling your tiller, start actual field
use with throttle in slow position.
To help tiller move forward, lift up the handles slightly (thus
lifting depth stake out of ground). To slow down the tiller,
press down on handles.
•
Youwillprobablynotneedtousethedepthstake.Begin
by tipping the depth stake forward until it is held by the
stake spring.
If you are straining or tiller is shaking, the wheels and depth
stake are not set properly in the soil being tilled.The proper
setting of the wheels and depth stake is through trial and
error and depends upon the soil condition. (The harder or
wetter the ground, the slower the engine and tine speed
needed. Under these poor conditions, at fast speed the
tiller will run and jump over the ground).
•
Cultivate up and down the rows at a speed which will
allow tines to uproot weeds and leave the ground in
rough condition, promoting no further growth of weeds
and grass (See Fig. 10).
A properly adjusted tiller will dig with little effort from the
operator.
•
Tilling is digging into, turning over, and breaking up

root growth. Best tilling depth is 4"-6". A tiller will also

of this vegetable matter enriches the soil. Depending
on the climate (rainfall and wind), it may be advisable
to till the soil at the end of the growing season to further
condition the soil.

to excessive bounce and difficult handling of your tiller.
Hard soil should be moistened before tilling; however,
extremely wet soil will “ball-up” or clump during tilling.
Wait until the soil is less wet in order to achieve the
best results. When tilling in the fall, remove vines and
long grass to prevent them from wrapping around the
tine shaft and slowing your tilling operation.

If possible, store your unit indoors and cover it to give
protection from dust and dirt.
