NOT INSTALLED PROPERLY? CARB ADJUSTMENT?
the belt might be to small try getting a smaller one
When working on a lawn mower, always make sure it is turned off, the spark plug is disconnected and the positive battery terminal is unhooked for your safety. First remover the belt keepers from around the belt. Next, you will be able to remove the belt from around the front pulley. Remover the deck from the mower by removing all the pins that keep it attached. You will now be able to remove the outer deck covers and loosen the remaining pulleys. Now you will be able to remove the belt and put the new belt on. You are ready to put the mower back together.
The belt tensioner probably needs to be replaced - about $110 @ PepBoys. Check the alignment of all pulleys. If something isn't aligned properly the belt will keep breaking.
The belt tensioner is probably bad.
Riding mowers sometimes have problems with the belts, especially the drive belt to the deck that drives the blade(s). The problem is often pulley alignment and that requires some mechanical repair. The other possibility is that the guides that are designed to keep the belt in the vee of the pulley are not adjusted properly. The third, and simplist, is to make sure that the correct belt is on the mower as per the manufacturer's instructions.In any case, unless you have adequate tools and knowledge of the drive mechanism, it might be better to check with a qualified mower mechanic.
Reasons: Cheap Belt Too tight
It might be the bearings are shot in your jack shaft.
some thing's probaly rubing on it. also check the clucth to see if it's working.
the main thing is that your belt that goes from the deck to the pulley beneath the pulley on the engine that makes the mower move there is a pulley below that and the belt is to tight. that is the only thing i can think of. hope this helps
You won't. Once they twist once, it keeps happening. You'll need a new belt
Either the belt is worn out, incorrect belt, drive gears are worn, or the tensioner is defective.
