Super Z - Move the control lever to where it is just
inside (1/8") the park brake slot. Fig. 5-11
NOTE: When the control lever is against the outside
edge of the the slot, the brakes should not be engaged.
6. Rotate the tire. If the brake is adjusted properly the
tire will still rotate but friction will start to become
noticeable here. However, if no brake resistance is
noticed, the brake needs adjusted as follows:
7. Loosen the brake linkage jam nuts. Fig. 5-13
8. Rotate the tire and at the same time rotate the
turnbuckle to shorten the length of the brake linkage to
increase the brake pressure. When you feel the brake
begin to engage, stop adjusting the turnbuckle. Re-
tighten the jam nuts on the turnbuckle.
9. Place the control lever in the park brake slot (Fig. 5-11
& 5-12). The tire should not rotate when the control
lever is in the park brake position.
10. Place the control lever in the neutral position. The tire
should rotate freely.
11. Close the hydraulic pump's bypass valve.
12. Repeat steps 3 thru 11 for the other side.
13. Remove the jack stands and lower the unit. It is now
ready to operate.

Hydraulic pump belt adjustment

The pump drive belt tension remains constant by means of
a tension idler and spring (Fig. 5-14). There is no tension
adjustment of this belt.

Deck drive belt adjustment

The spindle belt tension remains constant by means of a
tension idler and spring (Fig. 5-15). 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. 5-15). Installed spring length should be
9.0" ± .3" (22.8 cm ± .76 cm) originally with adjustments of
.60" (15.2mm) per chain link. (Fig. 5-16)
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.

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
Gauge wheels tire pressure...................8 - 10 psi
