a) Nylon shear pin is probably broken.
b) The reduction chain is broken or the connecting link is unlocked.
a) Replace shear pin.
b) Remove both chain guards. Inspect & repair chain if needed.
Shear bolt is probably broken.
Replace shear bolt.
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 blocked.
a) Adjust manual clutch cable or replace springs if stretched. To obtain the proper tension, the distance between the coils of the spring should 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 blocked before engaging.
a)Interference.
b) Improper tension.
c) Belt has flipped on its side.
d) Imperfections in pulleys.
e) Not original belts.
f) Height when snowblower is raised.
g) Not original shear bolts.
h) Alignment.
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.
a) Belt guides not well positioned.
b) New or cold belts flip off.
a) Guides must be in proper position to guide the belt into the pulleys properly.
b) After installation, turn on snowblower and watch the belt. If it flips, it will do this in the first few seconds. Remove belt and turn it around, reinstall and let it run. Sometimes it can take up to 4 times before the belts sits in the pulleys.
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.
Dirt or ice may be underneath chute.
Dismount chute by removing the rotation worm. Turn the chute completely towards the rear and it will disconnect from base. Clean the base of chute and the rotation ring. Lubricate & re-install.
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.
a) Tire pressure uneven from one side to another.
b) Maladjustment 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 & repair or replace fan.
d) Replace auger.
Belt is installed improperly.
See belt mounting instructions.
