Replacing the drive belt on a lawn mower

The drive belt is a vital component of both ride on and regular push lawn mowers. It is responsible for transferring the radial torque of the engine shaft to the input shaft of the transmission, which is what allows the mower to function.

There’s no set time for how long the drive shaft should last, and it could break and need replacement at any time. This part needs replacement due to wear and tear, which means the more you use your mower, the more likely the drive belt will need to be replaced.
