OPERATINGTHE TILLER
The following pages provide guidelinesto
using your tiller effectively andsafely in
various gardening applications. Besure
to read "Tilling Tips & Techniques" in this
Section beforeyou actually putthe tines
into the soil.
This is a CRT(counter-rotating tine) tiller.
As the wheels pull forward, the tines
rotate backward.
This createsan "uppercut" tine action
which digs deeply, uprooting soil and
weeds. Don't overloadthe engine, but dig
as deeplyas possible on each pass. On
later passes,the wheels may tend to spin
in the soft dirt. Helpthem along by lifting
up slightly on the handlebar(palm facing
up).
1. Followthe "Pre-Start Checklist" on the
previous page. Besure that the wheels
are in the WHEELDRIVEposition.
2. Put the Depth Regulator Leverin the
"travel" position (leverall the way down)
so that the tines are clear ofthe ground.
Usethis position when practicing with
your tiller or when moving to or from the
garden. When you are readyto begin
tilling, you must move the Depth
Regulator Leverto the desired depth
setting (see "Tilling Tips & Techniques").
Checkthat the Anti-Reverse Stakeswivels
freelybackandforth. Removeany clogged
material on or around the stake.

when movingforward.
3. Start theengine and allow it to warm
up. When warm, put throttle control in
fast speedsetting.
4. Forforward motion of wheelsand
power to thetines:
(a) Pull the ForwardClutch Bailup and

the bail to stop forward motion of
the wheelsand power to the tines.
(b) Asthe tiller moves forward, relaxand
letthe wheelspullthe unit alongwhile

little to one side ofthe tiller. Usea
light but secure grip with one hand
on the handlebars,keeping your arm
