&the snow thrower, shut off the engine, remove the spark plug wire(s), set the
parking brake and remove the key from the tractor ignition.CAUTION: Before servicing or adjusting
REPLACING AUGER BELT
•Release spring tension from the upper drive belt.
•Lower the snow thrower to the ground.
•Remove the attachment pin.
•Lock the snow thrower's lift handle in the down position to decrease auger belt tension.
•Release spring tension from the lower auger belt.
•Remove the auger drive belt from the clutch/idler assembly and from the spiral auger housing.
•Install new belt over top of large auger drive pulley and under the two side idler pulleys. Twist the belt 1/4 turn to seat the "V" of the belt in the groove of each idler pulley. Refer to figure 22 on page 12.
Assemble the belt onto the clutch/idler assembly. Refer to figures 23 and 24 on page 12.
SKID SHOE ADJUSTMENT
•The skid shoes are mounted on each side of the spiral auger housing. They regulate the distance the scraper plate is raised above the plowing surface. When removing snow from a gravel driveway or and uneven surface, it is advisable to keep the scraper plate as high above the surface as possible to prevent possible damage to the spiral auger. On blacktop or concrete, keep the scraper plate as close to the surface as possible.
•Raise the snow thrower off the ground and place a block under each end of the scraper plate. Loosen the six hex nuts securing the skid shoes to the housing. Adjust the skid shoes up or down and retighten the nuts securely. Adjust both skid shoes to the same height to keep the housing and the scraper plate level. See figure 29.
LIFT RELEASE CABLE ADJUSTMENT
•If the lift rod does not lock the snow thrower securely in the transport position, loosen the upper hex nut on the lift bracket a few turns and tighten the lower hex nut. Refer to figure 16 on page 10.
•If the lift rod fails to unlock completely to lower the snow thrower, loosen the lower hex nut on the lift bracket a few turns and tighten the upper hex nut. Refer to figure 16 on page 10.
SPIRAL AUGERS
•The spiral augers are secured to the auger shaft with two shear bolts and hex lock nuts. if you hit a foreign object or if ice jams the augers, the snow thrower is designed so that the bolts will shear.
•If the augers will not turn, check to see if the shear
bolts have sheared. See figure 30. Two replace- ment shear bolts and hex lock nuts have been
provided with the snow thrower. For future use
