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 in. (38 mm).
3. Remove the belt covers over the outside spindles.
4. Pull the idler pulley in the direction shown in Figure 44
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. 44).
