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. 5-15). This will set the cutting height
at 3-1/4 ". NOTE: Back of deck will automatically be
set 1/4" higher. NOTE: When blocking up the rear
discharge decks make certain the blocks are not in the
discharge opening.
NOTE: To level an XR7 deck use a 3” block under the
back of the deck and a 4” block under the front of the
deck. This will set the cutting height at 3-1/2 ".
4. Set cutting height at 3-1/4" 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. 5-16
NOTE: On a XR7 deck set cutting height at 3-1/2" in
the height indicator by placing the height adjusting
stop in the 3-1/2" hole, and turning the height stop so
that the pin side is against the stop handle.
5. Clamp the height adjusting stop against the stop handle
(5-16). This will assure that the height will not move
during the setting process. Otherwise, spring pressure
