HUSTLER FasTrak 36" & 42" Decks none Parts Manual page 94

Deck drive belt adjustment
The spindle belt tension remains constant by means of a tension idler and spring (FIG. 26). The spring ten-
sion 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. 26). Installed
spring length should be 7.50" ± .3) originally with adjustments of .60" per chain link. (FIG. 27).
IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.
Engine RPM setting
The FasTrak 36/42 is designed so that the engine will run at 3600 rpm (Kohler) or 3550 rpm (Honda) with
integrated pump/motor load only. At this speed the integrated pump/motors are running at their maximum
rated speed.

ing any mower deck leveling adjustments, check that the tire air pressure is within the specified range.
