Figure 19
Measure the distance from the front of the blade tip to the ground and the rear of the blade tip to the ground. The front edge of each blade should be lower than its back edge by 1/8” to 1/4”. Determine the appropriate distance necessary for proper adjustment and proceed, if necessary, to the next step.
Lower the deck to the lowest position.
Loosen the rear jam nuts on the front lift rods and turn the front lock nuts clockwise to raise the front of the mower deck or counterclockwise to lower the front of the mower deck. See Figure 21.
Raise the deck to the highest position. Recheck the blade measurements and repeat steps, if necessary.
Tighten the rear jam nuts after adjustments of the front lift rods are completed.
