HOW TO USE THE THROTTLE CONTROL
Use the throttle control to increase or decrease the speed of the
engine.
CAUTION: Always operate the engine with the throttle control
in the FAST position. If the engine runs for several minutes at
slower than the FAST position, the engine and transmission
will overheat and can be damaged.
1. Move the throttle/choke control completely forward to the
CHOKE position to start a cold engine.
2. The FAST position is marked with a detent. For normal opera-
tion and when using a grass bagger, move the throttle control
to the FAST position. For maximum charging of the battery and
for a cooler running engine and transmission, operate the en-
gine in the FAST position.
3. For transport and to tow pull behind attachments, control the
ground speed with the speed control pedal.
4. The engine governor is set at the factory for maximum perform-
ance. Do not adjust the governor to increase the speed of the
engine.
HOW TO USE
THE BLADE ROTATION CONTROL
The blade rotation control is next to the steering wheel (Figure 8).
Use the blade rotation control to engage the blade(s) or to operate
a snow thrower attachment.
1. Before you start the engine, make sure the
blade rotation con-
trol is in the DISENGAGE position .
2. Move the blade rotation control to the ENGAGE position to
rotate the blade(s).
Note: If the engine stops when you engage the blade(s),
the transmission is in reverse.
3. Move the blade rotation control to the DISENGAGE position
to stop the blade(s). Before you leave the operator’s position,
make sure the blade(s) has stopped rotating.
4. Before you ride the unit across a sidewalk or a road, move the
blade rotation control to the DISENGAGE position.
5. Before operating in reverse, move the blade rotation control to
the DISENGAGED position. If the blade rotation control is not
in the DISENGAGED position, the engine will stop when the
speed control pedal/shift lever is moved to REVERSE position.
WARNING: Always keep your hands and feet away
from the blade, deflector opening, and the mower
housing when the engine runs.
