Mower Belt Maintenance

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. Park the machine on a level surface and
disengage the blade control (PTO).
2. Move the motion control levers to the brake
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 1-1/2 inch (38 mm).
4. Remove the belt covers over the outside
spindles.
