CAUTION
Always release drive safety control levers to neutral
position before adjusting the depth regulator lev er .
Practice operating the controls and tiller with tines out
of ground before beginning to till. It is important that
you know how to use the tiller properly, how to keep
control at all times, how to stop the tines and wheels
from turning, and how to stop the engine if necessary.
If you do not know how to do these things, read the
Controls, Adjustments and Safety sections before
proceeding.

Tips
TILLING TILLING
TILLING
TILLING TILLING
The key to successful tilling is to begin with a shallow
cut on the first pass, and then work an inch or two
deeper on each successive pass.
✮ Tilling depth will v ary with ground conditions.
✮ When beginning to till in unbroken ground or in
extremely hard soil, set the detent pin in the highest
hole of the drag stake (follow instructions under
Tilling on previous page). This will allow for shallow
tilling. With the dr ag stake in this position, mak e
several light passes o v er the area to be tilled. Reset
for deeper depths with successive passes.
✮ If tiller jumps or skids uncontrollably, lower the drag
stake by placing the detent pin in a higher hole. This
will allow for shallower tilling. Hold firmly to the
handlebars to control sudden lurches.
✮ If weeds, tall g rasses, vines , or other materials clog
or jam the tines, rev erse the tiller to unwind
vegetation.
Immediately release the drive control lev ers if the tines
jam or you strike a foreign object. With drive control
levers in neutr al, push throttle control to
stop the engine. Disengage the spark plug wire. When
tines have stopped, remo ve foreign objects and check
for damage.

CAUTION
Extreme caution must be taken in selecting tilling
depth. If y ou attempt to till too deeply for soil conditions,
that is, with the drag stake in too high a position, loss
of control could result.
CAUTION
If removing material from the tines by hand, stop
engine and remove spark plug wire first.

If you plan to use your tiller for cultiv ating:
✮ Plant rows on 20" - 22" centers f or ease of turning.
✮ Set the drag stak e with the detent pin in one of the
higher holes. This will allow the shallow cultivation
necessary to turn over weeds, and break up and
aerate the soil.

Forward belt tension ma y decrease over time. It must be
adjusted within the first half hour of operation, and
checked after e v ery two hours of operation. Proper
adjustment will assure long belt life. Too much or too

check and adjust the forward belt tension:
1. Turn off engine. Engine must be cool.
2. Remove and secure spark plug wire from spark plug.
