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 the
spectacles or standard safety glasses.

HOW TO USE YOUR TILLER
BEFORE STARTING

•

YOUR TILLER

FILL THE ENGINE WITH OIL! Your tiller engine is
shipped without oil or gasoline. Add oil and gas as
instructed in the separate engine manual.

Repeat instructions in two preceding paragraphs
until engine fires. When engine starts, move choke
control gradually to RUN position.
Allow engine to warm up for a few minutes before
engaging tines.

FIG. 6

BREAKING

IN YOUR TILLER

Break-in your belts, pulleys and the control before you
actually begin tilling.
•
Start engine with tiller attached to tractor in transport
position. Engage "FineClutch Lever to start tine
rotation. Allow tines to rotate for five minutes.
•

Check fine operation and adjust if necessary. See
"TINE OPERATION CHECK" in the Service and
Adjustments section of this manual.

TRANSPORTING YOUR TILLER

•

if the soit is extremely hard and dry, it may be
desirable to cross till an area at shallow depth first,
then till in the direction of planting rows on the
second pass at the final depth.

•

Where possible, we recommend tilling in a pattern
similar to that shown in Fig, 7. Make the first pass,
then skip a space equal to the width of the tiller, and
make the return pass, Then till the skipped area.
Tilling in this pattern will enable you to maintain
better control. If the passes were made side-by-side,
the tractor and tiller would tend to pull toward the
tilled (soft) side.

•

Check ground moisture: If you can make a ball in
your hand out of ground to be tilled, do not till soil if
too wet. This causas lumps which are difficult to
work up,

•

When operating for the first time, proceed slowly and
carefully ur_it you become familiar with the proper
method of operating the tiller.

•

In soil that was tilled theyear before, select the
tilling depth at which the tiller engine runs
comfortably and does not stall or pull down. Lower
depth for additional passes if greater depth is desired.
Whenever working multiple passes, go perpendicular to
the previous tilling direction.
in cases where the soil is too hard to get proper
penetration or if tilling action causes Tiller to hop or
bounce, it will be necessary to purchase a set of Tiller
(Wheel) Weights.

AROUND THE YARD
•

Pull forward on lift handle until it locks in the up,
transport position.

AROUND TOWN
•
Disconneot spark plug wire.
•
Drain fuel tank.
•
Transport in upright position to prevent oil leakage.

TO ADJUST
•

•

DEPTH

STAKE

Depth stake has five position holes to select tilling
depth from 1 to 5 inches.
The top stake hole selects the shallowest tilling depth
and the bottom stake hole selects the deepest position,
TO change depth remove the hair cotter pin from the
clevis pin which is connecting the depth stake to the
stake support bracket
Grasp the top of the depth stake, remove the clevis pin
and reposition the depth stake. Insert clevis pin and
hair cotter pill,

IMPORTANT: THE DEPTH STAKE SHOULD NEVER BE
REMOVED FROM THE TILLER. IT IS DESIGNED TO
PROTECT THE TRACTOR TRANSAXLE FROM THRUSTING
ACTION OF THE TILLER.

•
=

TILLING
•

•

The most efficient tillage is obtained when Tiller
Engine is operated at full throttle. The sound of the
Tiller Engine wilt tell you. When Tiller Engine is
lightly loaded, raise Gauge Wheels to increase tilling
depth. If Engine seems to be overloaded or stalls out,
lower Gauge Wheels for shallower tilling.
Operate Tiller Engine at full throttle and operate
tractor in slowest forward speed, with tractor engine
at idle speed or just above idle_ You witl soon learn
the proper combination of tilling depth and speed for
good titiage_
Soil conditions witl determine how deep Tiller can
penetrate on the first pass. In extremely hard
ground, several passes may be necessary to till to a
depth of 6 inches. While in soft ground, Tiller may
penetrate to a depth of 6 inches in the first pass.

TILLING

CULTIVATING
Your tiller may be used for cultivating which requires
a minimum of two (2) inches of soil penetration,
Set depth stake so the Tiller will penetrate soil to a
depth of 2 to 3 inches. The Tiller Engine should be
run at full throttle except when cultivating small
plants. A slower engine is necessary to prevent
burying the plants. (See fig. 8).

NOTE: The following is a general guideline of tilling,

GENERAL

RECOMMENDATIONS

•

The warranty on this Tiller does not cover items that
have been subjected to operator abuse or negligence. To
receive full value from the warranty, operator must
maintain unit as instructed in this manual,

Once a year you should replace the spark plug, clean or
replace air filter, and check tines and belts for wear.
A new spark plug and clean air filter assure proper airfuel mixture and help your engine run better and last
longer.

BEFORE EACH USE

Some adjustments will need to be made periodically to
properly maintain your unit.
All adjustments tn the Service and Adjustments section of
this manual should be checked at least once each season.

•
.
•

Check engine oil level.
Check tine operation.
Check for loose fasteners.

LUBRICATION
Keep unit well lubricated (See "LUBRICATION CHART").
