Skid Shoes
Figure 10
The space between the shave plate and the ground can
be adjusted. For close snow removal, place skid shoes
in the low position. Use middle or high position when
area to be cleared is uneven.
•
•
One Wheel Driving: Insert the click pin only
through the outside hole of the axle (not the rim) on
the right side of the snow thrower. This position
gives power drive to the left wheel only, making the
unit easier to maneuver.
Both Wheels Driving: Insert the click pin through
the hole in the hub of the rim and the inside hole on
the snow thrower’s right axle. This position is good
for heavy snow as there is power drive in both
wheels.
Adjust skid shoes by loosening the four hex nuts
and carriage bolts and moving skid shoes to
desired position. See WARNING:.
Make certain the entire bottom surface of skid shoe
is against the ground to avoid uneven wear on the
skid shoes. Retighten nuts and bolts securely.
WARNING: Do not operate this snow
thrower on gravel as loose gravel can be
easily picked up and thrown by the auger
causing injury to the operator and/or damage
to the snow thrower.
IMPORTANT: Never operate the snow thrower with the
click pin inserted through both the rim and the outside
hole in the axle. Doing so can result in serious damage
to the drive system.
Drive Wheels
The wheels may be adjusted for two different methods
of operation. The adjustment is made by placing the
click pins in one of two different holes on the right side
of the unit. See Figure 10.

This limited warranty does not provide coverage in the following cases:

g.
MTD LLC does not extend any warranty for products
sold or exported outside of the United States, its possessions and territories, except those sold through MTD
LLC’s authorized channels of export distribution.
Parts that are not genuine MTD parts are not covered by
this warranty.
Service completed by someone other than an authorized
