Park brake switch adjustment
Occasionally the park brake switch may need adjustment. Use the
following method to adjust the switch:
1. Park the unit on a flat surface. Stop the engine and remove the
ignition key. Place control levers in the park brake position.
2. Loosen the screws holding the switch. Fig. 5-6
3. Slide the switch all the way down until it is fully activated (button
pushed in) against the brake actuator lever.
4. Tighten the screws.
Hydraulic pump belt adjustment
The pump drive belt tension remains constant by means of a tension idler
and spring (Fig. 5-9). 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. 5-10). 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. 5-10). Installed spring
length should be 7.50" ± .3" (19.05 cm ± .76 cm) originally with
adjustments of .60" (15.2mm) per chain link. (Fig. 5-11)
IMPORTANT: Do not over tension the spring to compensate for a
badly worn belt or pulley.
Engine RPM setting
The FasTrak is designed so that the engine will run at 3400 rpm with
integrated pump/motor 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. Remove ignition key. 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. 5-12). 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
