B. 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 adjust-
ments, place the PTO switch in the "OFF"
position, engage the parking brake, turn
the ignition key to the "OFF" position and
remove the key from the switch. Discon-
nect the spark plug wires for additional
safety. When handling the mower deck,
be careful not to cut yourself on the
sharp blades.
NOTE: Check the tires for proper inflation before
making a leveling adjustment. To level the deck, the
tractor and deck MUST be placed on a hard, level
surface during adjustment.
1. Position the tractor and mower deck on a hard,
level surface.
2. The mower deck front and rear gauge wheels
should be installed in their uppermost position in
the deck brackets to prevent contact with the hard,
level surface below. Refer to GAUGE WHEEL
ADJUSTMENT.
3. Raise the tractor implement lift handle to its
highest setting. Carefully rotate the outer cutting
blades so that they are positioned perpendicular to
the tractor frame (See Figure 45). Then lower the
deck to a mid-height setting using the tractor
implement lift handle.

4. Referring to Figure 46, measure and record the
distance from the hard, level surface to the outer-
most cutting edge of the right blade. Repeat this
step for the left blade. If the two blade heights are
not within 1/16 inch, note whether the right hand

blade is lower or higher than the left blade, then
proceed to steps 6, 7 and 8. If the two blade
heights are within 1/16 inch, proceed to FRONT
TO BACK LEVELING ADJUSTMENT.

5. Lower the deck onto the level surface.
6. Side-to-side leveling is obtained utilizing the
adjustment ferrule and right hand lift link rod (Refer
to Figure 47).
7. Loosen the upper jam nut on the lift link rod and
turn away from the adjustment ferrule. Turn the
lower lock nut upward (tighten) on the threads of
the rod to raise the right side of the mower deck.
Turn the lock nut down (loosen) on the threads to
lower right side of the mower deck (See Figure 47).

8. Raise the lift handle to the mid-height position
and recheck the blade measurements described
in step 4. If the blade measurements are not
within 1/16 inch, repeat steps 5, 7 and 8.
9. Tighten the upper jam nut against the adjustment
ferrule after side-to-side leveling is completed.
