REV B 4-6 125816
8. Rotate the tire. If the brake is adjusted properly the tire
will still rotate but friction will start to become
noticeable here. However, if no brake resistance is
noticed, the brake needs adjusted as follows:
a. Loosen the brake linkage jam nuts. (Figure 4-13)
Rotate the tire and at the same time rotate the
turnbuckle to shorten the length of the brake linkage
to increase the brake pressure. When you feel the
brake begin to engage, stop adjusting the turnbuckle.
Re-tighten the jam nuts on the turnbuckle.
b. Place the control lever in the park brake slot. The tire
should not rotate when the control lever is in the park
brake position. Figure 4-12
c. Place the control lever in the neutral position. The tire
should rotate freely.
9. Close the hydraulic pump’s bypass valve. Figure 4-11
10. Repeat steps 4 through 9 for the other side.
11. Check to make sure all tools or obstructions are
removed from under the mower.
12. Raise the rear of the mower and remove the jack
stands. Lower the mower.
13. Reconnect the negative battery cable.
14. Lower and secure the seat platform.
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 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 compen-
sate for a badly worn belt or pulley. Figure4-14
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.
Hydraulic System
IMPORTANT: Never use hydraulic or automatic transmis-
sion fluid in this system; use only motor oil as specified.
Remember, dirt is the primary enemy of any hydraulic sys-
tem.
Check oil level in hydraulic system after every 50 hours of
operation or weekly, whichever occurs first. Check more
often if system appears to be leaking or otherwise
malfunctioning.
Fluid level should be 1” (25.4 mm) from top of reservoir.
Use only 15W50 synthetic oil or 20W50 synthetic oil. Hustler
Full Synthetic 20W50 Hydrostatic Transmission Oil is
recommended. Figure 4-15
NOTE: The reservoir will require approximately 3 U.S. gal-
lons (11.35 liter) of 15W50 synthetic oil or 20W50 synthetic
oil when replacing the oil after an oil and filter change. Do not
overfill the reservoir.

If the transmission 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 dealer to resolve the problem.
