Inspecting the Belts

Inspect all belts every 100 hours.
Check the belts for cracks, frayed edges, burn marks, or
any other damage. Replace damaged belts.

Replacing the Mower Belt

Squealing when the belt is rotating, blades slipping when
cutting grass, frayed belt edges, burn marks, and cracks
are signs of a worn mower belt. Replace the mower belt if
any of these conditions are evident.
1. Stop the engine, set the parking brake, remove the key,
and disconnect the spark plug wire(s) from the spark
plug(s).
2. Set the height-of-cut at 1-1/2 inch (38 mm).
3. Remove the belt covers over the outside spindles.
4. Pull the idler pulley in the direction shown in
Figure 42 and roll the belt off of the pulleys.
Note: Do not remove the spring.
Caution
The spring is under tension when installed and
can cause personal injury.
Do not remove the spring from the spring eye
bolt.
5. Route the new belt through the idler arm and around
the idler pulley (Fig. 42).
