Snow Removal
1. The rotary broom works best on snow depths of
4 in. (10 cm) or less. Larger amounts of snow
can be moved if the ground speed is reduced.
2. To avoid snow being blown back onto the tractor
and operator, sweep with the wind blowing in
the direction of broom discharge.
Lawn Thatching and Leaf Raking
1. Bristles should barely touch the ground for lawn
thatching, and barely touch the grass in leaf rak-
ing operations.
2. Slower brush speed and ground speed are
more adequate for lawn thatching. This will pre-
vent “bouncing” which could damage the lawn
due to excessive ground contact.
3. Minimize dust by sweeping when moisture is
high (but not wet) whenever possible.
TWO-STAGE SNOWBLOWER CONTROLS
Chute Rotation Handle
The chute rotation handle is located on the rear of
the snowblower head, on the lower RH side of the
discharge chute. The chute rotates in a 228 degree
arc, by cranking the rotation handle. Turning the
handle clockwise rotates the chute clockwise.
Turning the handle counterclockwise rotates the
chute counterclockwise.

WARNING
Foreign objects in snow may be thrown
farther than the snow. Use the slowest
brush speed that will perform the job.

tion at all times.
CAUTION
Optional gauge wheels must be installed
to perform these types of operation in or-
der to avoid excessive brush ground con-
tact.
