Cutter Deck 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 Cutter Deck Belt

Squealing when the belt is rotating, blades slipping when
cutting grass, frayed belt edges, burn marks, and cracks
are signs of a worn cutter deck belt. Replace the cutter
deck 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.
