Mower Belt Maintenance

Inspecting the Belts
Service Interval: Every 25 hours—Check the belts for
wear/cracks.
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. Park the machine on a level surface and disengage
the blade control switch.
2. Move the motion control levers outward to the
park position, stop the engine, remove the key, and
wait for all moving parts to stop before leaving the
operating position.
3. Set the height-of-cut at 1.5 [1-1/2 inch (38 mm)].
4. Remove the belt covers over the outside spindles.
5. Pull the idler pulley in the direction shown in
Figure 45 and roll the belt off of the pulleys.
