Hydraulic pump belt adjustment
The pump drive belt tension remains constant by means of a tension idler and spring (FIG. 58). 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. 59). 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. 59). Installed spring length should be 9.0" -.0"/+ .6"
originally with adjustments of.60" per chain link (FIG. 59).
IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.
