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. 11-30). Installed spring
length should be 7.75" ± .3" (19.7 cm ± .76 cm) originally with adjustments
of .60" (15.2mm) per chain link. (Fig. 11-31)
IMPORTANT: Do not over tension the spring to compensate for a
badly worn belt or pulley.
Engine RPM setting
The 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. 11-32). 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. 11-33
