8. 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.
9. Place the control lever in the park brake slot "FIG. 28". The tire should not rotate when
the control lever is in the park brake position.
10. Place the control lever in the neutral position. The tire should rotate freely.
11. Close the hydraulic pump’s bypass valve.
12. Repeat steps 3 thru 11 for the other side.
13. Remove the jack stands and lower the unit. It is now ready to operate.
HYDRAULIC PUMP BELT ADJUSTMENT
The pump drive belt tension remains constant by means of a tension idler and spring "FIG. 30". There is
no tension adjustment of this belt.
NOTE: Replace the belt every 400 hours or every two (2) years whichever
comes first.
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.
DECK DRIVE BELT ADJUSTMENT
The spindle belt tension remains constant by means of a tension idler and spring "FIG. 31". 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 belt stretches and wears in, adjustment may become
necessary. To increase belt tension, move the spring chain one (or more) link(s) at the anchor bracket
"FIG. 31". Installed spring length should be 9.0" ± .3" (22.8 cm ± .76 cm) originally with adjustments of .60"
(15.2mm) per chain link "FIG. 32".
IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.
