Why does my belt keep slipping off my lawn mower?

The drive belt may come off a riding mower because it is damaged or loose. Even when it does not fall off, such a belt poses dangers. 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.

Do drive belts stretch over time?

Drive belts always stretch a little in use, because of the strains put on them by driving the water pump and generator , as well as the fan itself if it is in the system. Age and continual flexing also cause belts to crack and deteriorate. Stretching slackens a belt, so that it slips on the pulleys.
