Belt Replacement
Refer to Figure 5-17 and Figure 5-18:
Replace belts which show signs of severe cuts, tears,
excessive weather checking and cracking or burns
caused by slipping. Slight raveling of belt covering does
not indicate belt damage. Trim ravelings with a sharp
knife.
Inspect belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against
the bottom of the groove. Replace pulley when this is the
case, otherwise belt will lose power and slip excessively.
Never pry a belt onto a pulley as this will cut or damage
the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition
in a very short time.
Deck Belt Replacement Instructions
Refer to Figure 5-17:
1. Park mower on a flat surface. Stop engine and
remove ignition key. Make sure blade engagement
switch is in the down (OFF) position and spread
both control levers fully apart.
