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 Tine Clutch Lever to start tine
rotation. Allow tines to rotate for five minutes.
Check tine operation and adjust if necessary. See
TINE OPERATION CHECK in the SERVICE AND
ADJUSTMENTS section of this manual.
TRANSPORTING YOUR TILLER
AROUND THE YARD
• Pull forward on lift handle until it locks in the up,
transport position.
AROUND TOWN
Disconnect 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 pin.
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 will 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 will soon learn
the proper combination of tilling depth and speed for
good tillage.
Soil conditions will 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 HINTS
IMPORTANT OPERATING HINTS
NOTE: The following is a general guideline of tilling, but
may vary depending upon soil conditions.
In virgin soil, tiller should be started in shallowest
depth position and lowered one position at a time
after each pass in each direction.
If the soil 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 Figure 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 causes lumps which are difficult to work up.
When operating for the first time, proceed slowly and
carefully until you become familiar with the proper
method of operating the tiller.
In soil that was tilled the year before, select the tilling
depth at which the tiller engine runs comfortable and
does not stall or pull down. Lower depth for additional
passes if great 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 tiling action causes tiller to hop or
bounce, it will be necessary to purchase a set of tiller
(wheel) weights.
CULTIVATING
o
o
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 Figure 8.

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
air-fuel mixture and help your engine run better and
last longer.
Some adjustments will need to be made periodically to
properly maintain your unit.
All adjustments in the SERVICES AND ADJUSTMENTS
section of this manual should be checked at least once
each season.
BEFORE EACH USE
• Check engine oil level.
Check tine operation.
Check for loose fasteners
LUBRICATION
Keep unit well lubricated. See LUBRICATION CHART.

TINE CARE
For best results -- Tine Blades should be kept
reasonably sharp. The Tine Blade can be sharpened
on a grinding wheel. Do not attempt to sharpen Tines
while they are mounted to Tiller.
SPARE TINE DRIVE BOLTS
• The Tiller drive components are protected from
damage by (shearable) Grade 5 hex bolts in the
Tine Assemblies. The hex bolts drive the tines and
hold them in the proper location. Should the Tine
Assemblies strike or pick up a large hidden object
or become jammed, the hex bolts will break and the
drive components will not be damaged.
Two extra tine hex bolts and nuts are included with
the tiller. They are located in the Tiller Stake Support
Bracket on the rear of the Tiller.
The tine hex bolts are designed to be loose fit. Do not
attempt to use a bolt or pin that is larger or harder
than the original Grade 5 hex bolts.
Immediately prepare your tiller for storage at the end of
the season or if the unit will not be used for 30 days or
more.
CAUTION: Never store the tiller with
gasoline in the tank inside a building, where
fumes may reach an open flame or spark.
Allow the engine to cool before storing in any
enclosure.
ENGINE
Be sure that all nuts, bolts and screws are securely
fastened. Inspect moving parts for damage, breakage
and wear. Replace if necessary.
Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
If possible, store tiller indoors and cover it to protect
from dust and dirt.
Cover tiller with a suitable protective cover that does
not retain moisture. Do not use plastic. Plastic cannot
breathe, which allows condensation to form and will
cause your unit to rust.
Follow the instructions in the "Service & Storage"
section of the Engine Manual.
TILLER
WARNING: Never cover Tiller while
engine and exhaust areas are still warm.
Clean entire tiller (See CLEANING in the
MAINTENANCE section of the manual).
Inspect and replace belts, if necessary (See belt
replacement instructions in the SERVICE AND
