Skid Shoe

The space between the shave plate and the ground can be adjusted by raising or lowering the skid shoes.

Raise or lower the skid shoe to desired position.

Retighten the hex nuts loosened earlier.

Repeat on the other side of the snow thrower.

Rotate the ferrule up or down on the shift rod as necessary until the ferrule lines up with the upper

NOTE: Make certain the bottom surface of skid shoe is flat against the ground to avoid uneven wear.
