Mower Belt Maintenance

Inspecting the Belts

Service Interval: Every 25 hours—Check the belts
Check the belts for cracks, frayed edges, burn marks,
or any other damage. Replace damaged belts.

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. Ensure that the parking brake is engaged,
shut off 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 the lowest cutting position
of 38 mm (1-1/2 inches).
