Deck drive belt adjustment
The spindle belt tension remains constant by means of a tension idler and spring "FIG. 58". 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. 58". Installed spring length should be 9.0" ± .3" (22.8 cm ± .76 cm) originally with adjustments of .60"
(15.2mm) per chain link "FIG. 59".
IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.
Engine RPM setting
The Hustler Z is designed so that the engine will run at 3600 rpm static pump load only. At this speed the
hydraulic pumps are running at their maximum rated speed.
