Drive Belt Replacement

Signs of a worn belt are: squealing when belt is rotating,
blades slipping when cutting grass, frayed edges, burn
marks and cracks. Replace a belt if any of these condi­
tions are evident.
IMPORTANT: When installing new belts, do not
force over pulleys or kink belt in place. This could
fracture cords in belt, resulting in reduced belt life.
NOTE: Check tension of new belts after first 25 hours
of operation.
