Replacing the Mower Belt

Rear Discharge Machines
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 prevents 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.
1. Park the machine on a level surface, disengage
the blade-control switch, and engage the parking
brake.
