Replacing the PTO-Drive Belt
Service Interval: Every 50 hours
Squealing when the belt is rotating, blades slipping when
cutting grass, frayed belt edges, burn marks and cracks are
signs of a worn drive belt. Replace the drive belt if any of
these conditions are evident.
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Unlatch and remove the carrier-frame cover.
4. Unlatch and remove the belt covers.
5. Remove the heat shield from the engine deck and
carrier frame.
6. Roll the belt off of the center pulley on the mower
deck (
Figure 50 ).
Note:
Use caution when removing the belt, as tension
will increase because of the spring-loaded idler pulley.
7. Remove the belt from the engine pulley and the
spring-loaded idler pulley (
Figure 50 ).
8. Install the new belt onto the engine pulley and the
spring-loaded idler pulley (

the latches.
