Belt Maintenance

!
DANGER
Before raising the floor platform or removing pulley guards,
make certain the blade engagement switch has been shut off,
the deck has been properly blocked up, the engine has been
shut off and the ignition switch key has been removed for
maximum safety. Replace all guards and floor platform before
putting mower back into service.
Repairs or maintenance requiring engine power should be
performed by trained personnel only.
Refer to Figure 5-20 and Figure 5-21 on page 45:
Replace belts that 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.
