Refer to Figure 3-12:
The spindle 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 belt stretches
and wears in, adjustment may become necessary. To
increase belt tension, move the spring chain one (or more)

Engine RPM Setting

The Accu 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.

Deck Leveling and Height Adjustment

The mower deck has three areas that may need to be
checked and adjusted periodically. Before considering
any mower deck leveling adjustments, check that the tire
air pressure is within the specified range.
