Engine RPM setting
The Hustler Z Diesel is designed so that the engine will run at 2950 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:
WARNING: Stop engine. Make sure deck clutch switch is in the down (OFF) position. Remove igni-
tion 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. 61). This will
set the cutting height at 3 ½". NOTE: Back of deck will automatically be set ¼" higher.
4. Set cutting height at 3½" in the height indicator by placing the height adjusting stop in
the 3½" hole, and turning the height stop so that the pin side is against the stop handle,
FIG. 62.
5. Clamp the height adjusting stop against the stop handle. This will assure that the height
will not move during the setting process. Otherwise, spring pressure from the deck lift
springs will tend to pull the stop away from the handle.
6. Loosen all nuts on the deck lift threaded rods, and the hardware on the adjuster (on the
right front), until all the deck lift chains are loose, and the deck is sitting tightly on all four
blocks (FIG. 63, FIG. 64 & FIG. 65).
7. Loosen the two nuts on the front of height indicator so that the foot pedal is free
(FIG. 66).
8. Start the leveling process on the left front of the tractor.
9. Set the amount of threads protruding on the deck lift rod from the lift block at
approximately 1" (FIG. 67).
10. Jam both nuts against the block.
11. Push or pull on the deck lift foot pedal until the chain on the left front just becomes
tight, making sure that the deck stays tight against the 3" block.
12. While keeping the chain tight, tighten the nuts against the deck lift block on the height
indicator rod (FIG. 66).
13. Go to the right front of the tractor.
14. Loosen the 5/16" jam nut on the adjuster lift chain (FIG. 65), and back the adjuster bolt
out to allow the adjuster to move up and down freely.
