DECK LEVELING ADJUSTMENTS
In order to achieve even cutting, the mower deck must
be properly leveled. This leveling procedure will result in
the left and right blades having corresponding cutting-
edge-to ground measurements within 1/16 inch of each
other. Also, the blades will each have a 1/8 to 1/4 inch
downward tilt toward the front of the tractor. To level the
mower deck, proceed as follows:
WARNING
Before making any adjustments, place the PTO
switch in the "OFF" position, engage the parking
brake lever, and turn the ignition key to the "OFF"
position. When adjusting the mower deck, be
careful not to cut yourself on the sharp blades.
SIDE TO SIDE LEVELING ADJUSTMENT
NOTE: Check for proper tire inflation before checking
and/or making a leveling adjustment.
1. Position the tractor on a hard, level surface, and
use the tractor hydraulic lift system to raise the
deck to its highest position. Stop engine.
2. Carefully rotate the outer cutting blades so that
they are positioned perpendicular to the tractor
frame (See Figure 16).

3. Measure and record the distance from the sur-
face to the outer-most cutting edge of the right
blade (See Figure 17). Repeat this step for the left
blade. If the two blade heights are not within 1/16
inch, the deck must be leveled. Note whether the
left blade had the larger or smaller distance be-
tween the cutting edge and level surface. If the
two blade heights are within 1/16 inch, proceed to
