4.Refer to Figure 34. 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 33 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 clock- wise to raise the front of the mower deck, or counter- clockwise 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 must be against the back of both slots in the deck front roller bracket. If one side of the rod is not against the back 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 back of the slot.
9.Tighten the rear jam nuts after adjustment is completed.
10.Connect the spark plug wire.
