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. 11-31). Installed spring length should be 7.75" ± .3" (19.7 cm ± .76 cm) originally with adjustments of .60" (15.2mm) per chain link. (Fig. 11-32)

IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.

Engine RPM setting

The Super Mini 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. The recommended pressures are as follows:

Drive wheels tire pressure

8 - 10 psi

Gauge wheels tire pressure

8 - 10 psi

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" of blocking under all 4 corners of the deck (Fig. 11-33). This will set the cutting height at 3 ¼ ". NOTE: Back of deck will automatically be set ¼" higher.

4.Set cutting height at 3 ¼" in the height indicator by placing the height adjusting stop in the 3" hole, and turning the height stop so that the flat side is against the stop handle. Fig. 11-34

5.Clamp the height adjusting stop against the stop handle (11-34).
