Belt Maintenance

Inspecting the Belts

Inspect all belts every 100 hours.
Check belts for cracks, frayed edges, burn marks
or any other damage. Replace damaged belts.

when cutting grass, frayed belt edges, burn marks

levers to the neutral locked position and set
the parking brake.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
