REPLACING AUGER BELT

•Disengage the tractor's attachment clutch. Lower the snow thrower to the ground. Remove the attachment pin.

Lock the snow thrower's lift handle in the down position to decrease belt tension.

Release the spring tension from the auger belt idler arm on the bottom of the clutch/idler assembly. 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 55 on page 24.

Assemble the belt onto the clutch/idler assembly.

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 surface, 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 59.

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 48 on page 22.

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 48 on page 22.

CLUTCH DISENGAGEMENT ADJUSTMENT

(For tractors with engagement rod clutches only. Not for electric clutches or cable clutches)

If the spiral auger on the snow thrower does not stop when the attachment clutch lever on the tractor is

disengaged, then adjustment is necessary. Proceed as follows. Refer back to figure 33 on page 17.

Place the attachment clutch lever in the disengaged position.

Remove the hairpin cotter from the engagement rod trunnion and lift the trunnion out of the hole in the idler

arm.

Screw the trunnion a few turns towards the front end of the rod.

Replace the trunnion into the hole in the idler arm and secure it with the hairpin cotter.

Check the operation of the snow thrower. If the spiral augers still do not stop, repeat the above steps until the augers stop when the attachment clutch lever is placed in the disengaged position.

SPIRAL AUGERS

The spiral augers are secured to the auger shaft with two shear bolts and nylock 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 60. Two replacement shear bolts and nylock nuts have been provided with the snow thrower. For future use order part number 710-0890A shear bolt and number 47810 nylock nut.
