correct adjustment is reached.
Reassemble the frame cover.

certain to remove it before operating the snow thrower.
Shift Rod Adjustment
Remove the hairpin clip and flat washer from the
shift handle under the handle panel. See Figure 12.
Place shift lever in sixth (6) position or fastest
forward speed.
Push shift arm assembly down as far as it will go.
Rotate the ferrule up or down on the shift rod as
necessary until the ferrule lines up with the upper

IMPORTANT:
Make certain to check for correct
adjustment of the shift rod as instructed under “Drive
Control and Shift Lever” on page 11, before operating
the snow thrower.
Skid Shoe
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 13.
Adjust skid shoes as follows:
Loosen, but do not remove, the three hex nuts
which fasten the skid shoe to the auger housing.
Raise or lower the skid shoe to desired position.
Retighten the hex nuts loosened earlier.
Repeat on the other side of the snow thrower.
NOTE: Make certain the bottom surface of skid shoe is
flat against the ground to avoid uneven wear.
