Why does my drive belt keep coming off my riding mower?
The drive belt may come off a riding mower because it is damaged or loose. When loose, the belt may slip, resulting in friction that, if it creates enough heat, can lead to a fire in the mower’s engine.
What does the drive belt do on a riding mower?
The ground drive belt connects the engine crankshaft to the transaxle pulley to drive the rear wheels. If the belt breaks, the lawn tractor won’t move. If the belt is worn, the lawn tractor moves sluggishly because the belt slips on the pulley.
How do you replace a belt on a MTD deck?
How to Replace a Deck Belt on a MTD Riding Mower
- Push the deck adjuster into the lowest height possible.
- Tap the screws located around the belt.
- Pull the belt keeper rod off the belt.

How do you tighten the drive belt on a Craftsman riding lawn mower?
Push the belt keepers on the transaxle pulley down and slide the belt over the transaxle pulley. Pull the slack from the back of the tractor (transaxle pulley) and slide the belt on to the stationary and clutch idlers. This will increase the tension in the belt and hold it in place.
How often should I change the belt on my riding mower?
There’s no definite amount of time that a mower belt is supposed to last, but increased mower use shortens the interval in which a belt needs replacement. Simply put, more use equals more wear. Additionally, faulty belts or mechanical failures like a seized pulley can make lawn mower belts break prematurely.
What happens if a belt breaks while driving?
If a timing belt breaks, the engine will no longer work. If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. The heavier crankshaft will continue rotating by inertia, moving pistons up and down.
How tight should riding mower belt be?
Roughly, starting out about as tight as an alternator belt, maybe an inch of play side to side So, tight but not super tight, hard to explain it just takes practice. Too tight is no good, I find if it’s tight enough where it doesn’t slap around at all then it’s also too tight, ain’t life grand.
