Adjustments
A WARNING
To avoid serious injury, perform adjustment
procedures on the tractor only when the engine is
stopped. Always remove the ignition key before
beginning the adjustment procedures to prevent
accidental starting of the engine.
SKID SHOE ADJUSTMENT
The skid shoe can be adjusted up or down to keep the
snowthrower working efficiently on various types of
surfaces.
On smooth, hard surfaces, such as concrete or asphalt,
the skid shoes should be adjusted so that the scraper bar is
resting on the surface.
To adjust the skid shoes up or down, loosen the two nuts
holding each skid shoe and move the skid shoes to the
desired position (see figure 15). Tighten the nuts securely,
making sure the skid shoes are parallel to the ground
surface and both adjusted to the same level.
On rough surfaces, such as gravel, the skid shoes should
be adjusted down. This helps to keep the scraper bar
above the ground so that it does not pick up stones. Use
scraps of wood to raise the scraper bar about 1 inch (25
mm) above the level ground surface. Then drop the skid
shoes down to the ground, keeping the bottom edge of the
skid shoes level. The snowthrowers will now be
supported by the skid shoes.
DRIVE BELT TENSION
1. Pull the belt tensioning lever back and up to engaged
position to tighten the belt.
2. Locate the decal on the front idler pulley bracket
shown in figure 16. Notice it has a front red zone, a
green zone and a rear red zone. The rear edge of the
front idler bracket should be in the front edge of the
front red area as in figure 16. If not, go on to step 3.

3. Push the belt tensioning lever down to release belt
tension.
4. Loosen the fasteners which secure the rear idler in the
slot. To move idler bracket forward, move the rear
idler pulley toward the rear. To move idler bracket
rearward, move the rear idler pulley toward the
front. Tighten the fasteners.
5. Pull the belt tensioning lever up to engaged position
to tighten the belt.
6. The rear edge of the idler bracket should be in the
front edge of the front red area as in figure 16. If not,
repeat the adjustment procedure.
Xk. CAUTION
In no instance should the belt, where it passes
behind the front idler pulley, come in contact with
the rear idler pulley. Allow sufficient clearance.
