Belt Maintenance
Inspecting the Belts
Service Interval: Every 25 hours—Check the belts
for wear or cracks.
Replace the belt if it is worn. The signs of a worn belt
include squealing while the belt is rotating; the blades
slipping while cutting grass; and frayed edges, burn
marks, and cracks on the belt.
