3. When the ball stud is loosened, pull out on the ball stud stud end and
release. The dampener will return to the neutral position and come
to rest. Re-tighten the front ball stud.
4. Release the park brake and pull the steering lever to the reverse
position and allow the dampener to return the lever to the neutral
position. If the steering lever does not return to the neutral position
(centered with the brake slot), then either you have not adjusted the
dampener correctly, or it is damaged and needs to be replaced.
5. Repeat for the opposite side.
Hydraulic pump belt adjustment
The pump drive belt tension remains constant by means of a tension idler
and spring (Fig. 9-23). There is no tension adjustment of this belt.
NOTE: Inspect the belt every 100 hours and replace as needed.
Replace the belt every 200 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. 9-24). 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. 9-24). Installed spring
length should be 7.50" ± .3" (19.05CM ± .76CM) originally with adjustments
of .60" (15.2MM) per chain link. (Fig. 9-25)
IMPORTANT: Do not over tension the spring to compensate for a
badly worn belt or pulley.
Engine RPM setting
The FasTrak 36/42 is designed so that the engine will run at 3600 rpm
(Kohler) or 3550 rpm (Honda) with integrated pump/motor load only. At
this speed the integrated pump/motors 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 (55-69
KPa)
Gauge wheels tire pressure...................8 - 10 psi (55-69
KPa)
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" (7.62CM) tall spacer blocks under the edge
of the deck - two in front on each side and two in back on each side
(Fig. 9-26). Remove the height adjusting stop and let the deck down
so it rests on the 3” (7.62CM) spacer blocks. Make sure the deck is
setting on all four blocks. Leave the height adjusting stop out of the
square adjusting bar for now. The deck should be leveled before the
height is set. Fig. 9-27
4. Loosen the two nuts that hold the deck adjusting bar in position.
Fig. 9-30
5. Loosen the two nuts that hold the right rear deck lifting arm. Fig. 9-
28
6. Loosen the left rear deck leveling bracket by loosening the flange
nuts. Fig. 5-14
7. Loosen the jam nut and back out the 5/16” bolt on top of the
adjuster. Fig. 9-29
8. Check to make sure the deck is resting firmly on all of the 3”
(7.62
CM) blocks. Check the front right deck chain to be sure it is
taut. Now, screw both nuts finger tight against the square block on
the right rear deck lift arm. Tighten these two nuts. Fig. 9-28
9. Tighten the 5/16” bolt on the adjuster until the chain is taut. Tighten
the jam nut against the adjuster. Tighten the two flange nuts. The
deck should now be level. Fig. 9-29
10. To adjust the deck height insert the height adjusting stop into the 3-
1/4” (8.26CM) position. (Fig. 9-27) Remember, the blocks are 3”
(7.62CM) and the blades are set 1/4” (6.35MM) higher than the front
edge of the deck, so the cutting height is currently at 3-1/4”
(8.26CM).
11. Tighten the rear nut against the block attached to the deck lifting
pedal as tight as you can by hand. (Fig. 9-30) Make sure the stop
handle is pushing firmly against the height adjusting stop so that
there is no free play forward or rearward when you shake the
adjustment bar. Fig. 9-27
12. Finger tighten the front nut against the block attached to the deck
lifting pedal. Tighten both nuts and check to make sure that all deck
