Belt replacement
Figures 4-14 and 4-15 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.
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!
Mower blade removal
Use a 15/16" wrench to remove the 5/8" cap screw
holding the blade to the spindle shaft from underneath.
Sharpen the blades on a grinder following pattern as
shown (Fig. 4-16). Touch-up sharpening can be done with
a file.
Check the blades for balance following grinding. A
commercial balancing tool is available through most
hardware supply stores, or balancing can be done by placing
the blade on an inverted line punch or 5/8" bolt. Blade
should not lean or tilt. Spin the blade slowly, blade should
not wobble. If blade is out of balance, true it up before
reinstalling.
Lay the blade on a flat surface and check for distortion
(Fig. 4-17 and 4-18). Replace any distorted blade.
Do not re-use spindle bolts which have stripped, worn or
undercut threads. Torque bolts to 118 foot-pounds when
reinstalling blades.
WARNING: When mounting blades, rotate
them after installation to ensure blade tips do not
touch each other or sides of the mower.
WARNING: Failure to correctly torque the bolt
may result in the loss of the blade which can
cause serious injury.
WARNING: Mower blades are sharp and can
cut. Wrap the blade(s) or wear gloves and use
extra caution when servicing them.
