Traction Drive Clutch and Shift Lever Adjustment

To check the adjustment of the traction drive clutch and shift lever, move the shift lever all the way over to fifth (5) position. With the traction drive lever released, push the snow thrower forward. The unit should move forward freely. Then engage the traction drive clutch grip. The wheels should stop turning.

Now release the traction drive clutch grip, and push the unit again. Move the shift lever back to the fast reverse position, then all the way over again. There should be no resistance in the shift lever, and the and the wheels should keep turning

If you have resistance when moving the shift lever or the wheels stop when they should not, loosen the jam nut on the traction drive cable and unthread the cable one turn. If the wheels do not stop when you engage the traction drive clutch grip, loosen the jam nut on the traction drive cable and thread the cable in one turn. Recheck the adjustment and repeat as necessary. Tighten the jam nut to secure the cable when correct adjustment is reached.

NOTE: If you are uncertain that you have reached the correct adjustment, refer to the Adjustment section.
