Adjusting the Deck
Leveling the Deck (Front-To-Rear)
The front of the cutting deck is supported by a stabilizer bar that can be adjusted to
level the deck from front to rear. The front of the deck should be between 1⁄4-3⁄8”
lower than the rear of the deck. Adjust if necessary as follows:

Leveling the Deck (Side-to-Side)
If the cutting deck appears to be mowing unevenly, a side to side adjustment can be
performed. Adjust if necessary as follows:

and the distance from the outside of the right blade tip to the ground. Both
measurements taken should be equal. If they’re not, proceed to the next
step.

To raise the left side of the deck, loosen the upper nut on the end of the
lift rod, then turn the lower nut clockwise. When the proper adjustment is
achieved, tighten the upper nut to secure in place. To lower the left side of
