CORRECTIVE ACTIONS :

a) Make sure that belt does not come into contact with any other part, bolts, guides etc... when engaged.

b) Make proper adjustement, verify if springs are stretched from use, if so, replace springs. Check in which hole on the tension arm of the snowblower, the spring is installed. There is too much tension.

c) When installing new belt, have snowblower run under supervision for a few minutes. Turn everything off and verify that belt has not turned on its side. If so, remove belt and reinstall in opposite fashion to rectify the bad twist the belt has taken.

d) Verify that pulleys are smooth, have no rust spots or weld burrs. Sand down pulleys or replace.

e) Always use original belts. See parts breakdown in subframe / drive mechanism owner's manual for part number. 

f) Should not exceed 4 inches off ground. Make adjustment as per instructions in owner's manual.

g) Use original shear bolts.

h) Verify alignment of belt. Make sure belt is feeding well into pulleys. If not, adjust pulleys properly.

#10 - Snowblower digs into ground.

POSSIBLE CAUSES :

Ground is not frozen or too soft.

Adjust skid shoes lower so they may better support the snowblower. If problem persists, change skid shoes for heavy duty skid shoes (option #700243) which cover more surface and prevents snowblower from digging into the ground.
