Hustler Turf Diesel Z - Manual (Page 142)

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 these belts frequently for wear and serviceability. Replace a belt that shows signs of severe cuts, tears, sep-
aration, weather checking and cracking, or burns caused by slipping. Slight raveling of belt covering does not indicate
failure, trim ravelling with a sharp knife.
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. Replace worn or damaged blades.
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!
WARNING: Always wear adequate eye protection when grinding mower blades.
