Skid ShoeAdjustment
The space between the shave plate and the ground can
be adjusted by raising or lowering the skid shoes.
For close snow removal, as when using on a smooth
concrete or asphalt driveway, place the skid shoes in
the low position. Use the middle or high position when
the area to be cleared is uneven. When operating on
gravel, always put skid shoes in the high position.
See Figure 11.
Adjust skid shoes as follows:
• Loosen, but do not remove, the three hex nuts
which fasten the skid shoe to the auger housing.
