Belt replacement
Figures 11-13 and 11-14 show diagrams and descriptions of the unit’s
belt drive systems.
Inspect these belts frequently for wear and serviceability. Replace a belt
that shows signs of severe cuts, tears, separation, weather checking and
cracking, or burns caused by slipping. Slight raveling of belt covering does
not indicate failure, trim ravelings with a sharp knife.
WARNING: If the pump belt fails, loss of control will occur
especially when operating on a slope. If you lose steering
control while operating the machine, place the steering
control levers in the park brake position immediately. Inspect
the machine and involve your Hustler dealer to resolve the
problem before continuing to operate.
Inspect the 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 the pulley when this is the case, otherwise belt will lose power and
slip excessively.
Never pry a belt to get it on 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.
Mower blade maintenance
Check the mower blades daily, they are the key to power efficiency and
well groomed turf. Keep them sharp, a dull blade will tear rather than cut
the grass, leaving a brown ragged top on the grass within a few hours. A
dull blade also requires more power from the engine.
Replace any blade which is bent, cracked or broken.
WARNING: Never attempt to straighten a bent blade by heating,
or weld a cracked or broken blade as the blade may break and
cause serious injury.
DANGER: Never work with blades while engine is running or
deck clutch is engaged. Always place deck clutch in the
disengaged position, engage parking brake and neutral lock
levers and turn engine off. Block up mower when you must
work under it. Wear gloves when handling blades. Always
check for blade damage if mower strikes rock, branch or other
foreign object during mowing!
