Slight raveling of belt covering does not indicate failure,
trim ravelings 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 the 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.
Hydraulic Pump Belt Adjustment
The transmission drive belt tension remains constant by
means of a tension idler and spring. The spring tension
should be such that the belt does not slip under normal
operating load conditions, assuming the belt is not
excessively worn or damaged. As the belt stretches and
wears in, adjustment may become necessary.
The proper belt tension is achieved when the tension
spring is stretched to a dimension of 8.75"–9.25" (222–
223 mm) when measured from the outside of the hook to the
outside of the other hook. Figure 4-14
To increase belt tension, loosen the jam nut on the eye
bolt. Then, tighten the nut on the eyebolt until the 8.75"–
9.25" (222–223 mm) dimension is attained. Lock the eyebolt
in place by tightening the jam nut. Figure 4-14
IMPORTANT: Do not over-tension the spring to
compensate for a badly worn belt or pulley.
Inspect the spring tension adjustment after the first 50
hours. Adjust as needed.
Inspect the belt every 100 hours and replace as needed.
Replace the belt every 400 hours or every two (2) years
whichever comes first.
Mower Blade
Mower Blade Maintenance
IMPORTANT: Refer to the Safety section of this manual for
blade handling safety information.
Refer to the Mower Blade Replacement section for blade
removal and installation.
Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep the blades 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.
Sharpen the blades following the pattern shown. Touch-up
sharpening can be done with a file. Figure 4-15
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.

Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing them.
Always check for blade damage:
• if mower strikes a rock, branch or other
foreign object during mowing!
• or if an abnormal vibration occurs while
operating.
Make all necessary repairs before resuming
operation.
