To Change From HIGH Range to

1. To avoid personal injury, shut
off engine, let all moving parts
come to a complete stop, then dis-
connect spark plug wire and move
it away from the spark plug before
making any adjustments.
2. Move the WheelsffineslPTO
Drive Lever to NEUTRAL.
3. Stand on left side of tiller. Use
your right hand to hold the
WheelsffineslPTO Drive Lever
UP in REVERSE position. Then
use left hand to move belt from

from the front groove to the rear

5. Check that the belt is fully
seated in the pulley grooves. Look
at this from both sides of the tiller.
Choosing Tiller Wheel
and Tine Speeds
Your tiller offers/our wheel/tine
speed combinations to handle ev-
ery tilling task and garden job. By
experimenting, you'll find the right
tilling depth, engine speed, and
wheel and tine speed combination
that is best for the soil in your gar-
den. Here's how to approach jobs:
1. Advance the throttle lever so
the engine has sufficient power.
2. Do not set the depth regulator at
too deep a setting to avoid having
the engine labor or the tiller buck.
3. Your settings are "ideal" when
the tines are breaking up the soil
nicely, the engine is not laboring,
and your progress is steady and
smooth. See the Selection Guide
below for hints.
WARNING
The HIGH speed belt range
position combined with a
FAST wheel speed setting
propels the tiller at the
fastest pace. To help avoid
personal injury or property
damage if using this speed
combination, reduce the en-
gine throttle speed.
WHEEL SPEED AND BELT RANGE SELECTION GUIDE
IMPORTANT - For correct wheel speed and belt range choices when using attachments or accessories
other than tines, read the Owner/Operator Manual provided with the attachment or accessory.
