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: INever 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: INever work with blades while engine is running or deck clutch switch is engaged (on).
Always place deck clutch switch in the disengaged position, place control levers in the park brake posi-
tion and turn engine off and disconnect negative battery cable. 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!
WARNING: IAlways wear adequate eye protection when grinding mower blades.
Mower blade removal
Use a 15/16" wrench to remove the 5/8" cap screw holding the blade to the spindle shaft from underneath.
