Checking and Replacing Traction Drive Belt

Entanglement in a belt or pulley can cause serious injury. Stop engine and wait for all moving parts to stop.

The traction drive belt is self-adjusted using a spring tensioner and does not require a tension adjustment.

Checking Belt:

1. Park machine safely. (See Parking Safely in the SAFETY section.)

2. Inspect belt for excessive wear, damage or stretching while in position on the transmission pulley and drive belt tensioner pulley.

Replacing Belt
