Shear bolts are probably broken.
One of the two belts is probably damaged or broken.
Check both belts and replace damaged belt(s).
a) Lack of tension on belt.
b) Snowblower engaged when plugged.
a) Adjust manual clutch cable or replace springs if stretched. To obtain the proper tension, the distance between the coils of the spring sould be .25'' (1/4''). If not, remove the bolt, sleeve and the spring from the original hole and reinstall them in the second hole.
b) Make sure the auger & the fan are not frozen or plugged before engaging.
a) Tractor engine turning too slowly.
b) Advancing too quickly with tractor.
a) Run engine at full throttle while snowblowing.
b) Allow snowblower to ingest snow at its own speed.
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.
a) Tire pressure uneven from one side to another.
b) Maladjustement of the snowblower.
a) Verify and adjust tire pressure:
Front tires: 14 to 15 psi / Rear tires: 7 to 8 psi
b) Loosen male hitch on snowblower. Place a shim (ex: piece of wood approx. 2'' thick) under the lowest side of snowblower which needs to be leveled. Re-tighten bolts.
a) Damaged pulley.
b) Damaged bearing.
c) Damaged fan.
d) Damaged auger.
a) Replace pulley.
b) Replace bearing.
c) Dismount & repaire or replace fan.
d) Replace auger.
