3. Adjust the right brake cleat so that the gap between it
and the tire is .25". Repeat for the left side. Figure 4-16
& Figure 4-17
4. Engage park brake lever. The park brake plate should
push in on the tire to prevent it from rotating.
If one of the brake cleats does not fully engage the tire
then it may be necessary to adjust the brake cleat until
it fully engages the tire.
Belts
Inspect belts frequently for wear and serviceability.
Replace a belt that shows signs of:
• severe cuts
• tears
• separation
• weather checking
• cracking
• burns caused by slipping.
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 the appropriate dimension when
measured from the outside of one hook to the outside of the
other hook. Figure 4-18
To increase belt tension, loosen the jam nut on the eye
bolt. Then, tighten the nut on the eyebolt until the
appropriate dimension is attained. Lock the eyebolt in place
by tightening the jam nut. Figure 4-18
IMPORTANT: Do not over tension the spring to compen-
sate for a badly worn belt or pulley.
Inspect the belt every 100 hours and replace as needed.
Replace the belt every 400 hours or every two (2) years
whichever comes first.

If the pump belt fails, loss of steering control will
occur especially when operating on a slope. If you
lose steering control while operating the mower, turn
the engine off and, if on a slope, step off of the
operator’s platform to the uphill side. Inspect the
machine and involve your Hustler

Dealer to resolve
the problem before continuing to operate.
