9. Raise the lift handle to the highest position and
recheck the blade measurements described in

FRONT TO BACK LEVELING ADJUSTMENT
1. Raise the deck to its highest position.
2. If making the initial installation of the deck, adjust
the front lift rod to allow 5/8 inch of thread to
protrude beyond both lock nuts of the front lift rod/
bracket assembly (See Figure 51).
Figure 51
3. Position the mower blades so the ends of each
blade point to the front and the rear of the tractor
(See Figure 52).
Figure 52
4. Refer to Figure 53. Measure and record the
distance from the front cutting edge to the ground
(measurement A), and from the rear cutting edge
to the ground (measurement B), for each of the
blades. The front edge of each blade
(measurement A) should be lower than its back
edge (measurement B) by 1/8 to 1/4 inch.

5. Lower the deck onto the hard, level surface.
6. To adjust the downward tilt of the blades,
adjustment of the front lift rod is required. Refer to
Figure 51 and proceed as follows:
7. Loosen the rear jam nuts on the front lift rod. From
the front of the tractor, turn the front lock nuts
clockwise to raise the front of the mower deck, or
counterclockwise to lower the front of the mower
deck.
8. Raise the deck to the highest position. Recheck
the blade measurements described in step 4. If the
resultant measurements are not correct, repeat
steps 5, 6 and 7 until the proper measurements are
obtained.
NOTE
The front lift rod should be against the front of
both slots in the deck front roller bracket. If one
side of the rod is not against the front of the slot
after attaining the correct front pitch to the deck,
tighten the front lock nut on that side until the
rod just contacts the front of the slot.
9. Tighten the rear jam nuts after adjustment of the
front lift rod is completed.
10. Connect the spark plug wires if previously
disconnected.
