Belt Maintenance
Inspecting the Belts
Service Interval: Every 50 hours
Check the belts for 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.
Replacing the Mower Belt
Important: The fasteners on the covers of this machine
are designed to remain on the cover after removal.
Loosen all of the fasteners on each cover a few turns so
that the cover is loose but still attached, then go back
and loosen them until the cover comes free. This will
prevent you from accidentally stripping the bolts free
of the retainers.
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.
