the jam nuts until they are tight against the turnbuckle.
NOTE: It may be necessary to loosen the jam nuts
before turning the brake linkage.
3. Repeat steps 1 thru 2 for the other side.
4. The brakes should now be set.

Hydraulic pump belt adjustment

The pump belt belt tension remains constant by means of
a tension idler and spring (Fig. 5-11). 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,
adjustment may become necessary. To increase belt tension,
move the spring chain one (or more) link(s) at the anchor
bracket (Fig. 5-11). Installed spring length should be 9.0" ±
.3" (22.8 cm ± .76 cm) originally with adjustments of .60"
(15.2mm) per chain link. (Fig. 5-13)
IMPORTANT: Do not over tension the spring to
compensate for a badly worn belt or pulley.
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. 5-12). 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,
adjustment may become necessary. To increase belt tension,
move the spring chain one (or more) link(s) at the anchor
bracket (Fig. 5-12). Installed spring length should be 9.0" ±
.3" (22.8 cm ± .76 cm) originally with adjustments of .60"
(15.2mm) per chain link. (Fig. 5-13)
IMPORTANT: Do not over tension the spring to
compensate for a badly worn belt or pulley.

Engine RPM setting

The Super Z Diesel is designed so that the engine will run
at the following settings:
High idle - 3100 ±50 rpm At this speed the hydraulic
pumps are running at their maximum rated speed.
Low idle - 1200 ±50 rpm

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.

Deck level adjustments
Leveling the deck must be done in the following manner
and order:
1. Check tire pressures to make certain they are properly
inflated before starting to level deck.
recommended pressures are as follows:
Drive wheels tire pressure .......8-10 psi (55-69
Gauge wheels tire pressure ......8-10 psi (55-69
WARNING: Stop engine. Make sure deck
clutch switch is in the down (OFF) position.
Place control levers in the brake position before
leaving machine.
2. Park the unit on a flat surface.
3. Raise deck and place 3" (7.62
all 4 corners of the deck (Fig. 5-14). This will set the
cutting height at 3 ¼ " (8.26). NOTE: Back of deck
