The shave plate and skid shoes on the bottom of the
snow thrower are subject to wear. They should be
checked periodically and replaced when necessary.
• To remove skid shoes, remove the four carriage
bolts, cupped washers and hex nuts which attach
them to the snow thrower. Reassemble new skid
shoes with the four carriage bolts, cupped washers
(cupped side goes against skid shoes) and hex
nuts. Refer to Figure 16.
• To remove shave plate, remove the carriage bolts,
cupped washers and hex nuts which attach it to the
