maintenance are specified in the Engine Owner’s manual. Please refer to
this manual for engine servicing, lubricating oil levels with quality and
viscosity recommendations, bolt torques, etc. The engine warranty is
backed by the manufacturer. Special attention should be paid to applicable
data which will not be duplicated here.
Belt replacement
Figures 12-13, 12-14 and 12-15 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. NOTE: Replace the
belt every 400 hours or every two (2) years whichever comes first.
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 switch is engaged (on). Always place deck clutch
switch in the disengaged position, place control levers in the park
brake position 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!
