Leveling The Mower
If the cut is uneven, the mower may need leveling.
NOTE: Unequal or improper tire pressure may also
cause an uneven cut.
SIDE TO SIDE LEVELING
1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
2. Place the cutting height adjust in high-cut position.
3. Set the parking brake, turn off the ignition, and
remove the key.
4. Check for bent blades and replace if necessary.
5. Arrange the mower blades so that they are pointing
from side-to-side.
6. Measure the distance between the outside tips of
each blade and the ground. If there is more than 1/8"
(3mm) difference between the measurements on
each side, proceed to step 7. If the difference is 1/8"
(3mm) or less, proceed to Front To Back Leveling.
7. See Figure 46. Prevent I-Bolt (C) from turning; then
adjust spacer (B) by turning lock nut (A) clockwise
(up) or counter-clockwise (down) to achieve correct
side to side leveling.
FRONT TO BACK LEVELING
1. Arrange the blades so they face front-to-back.
2. Measure the distance from the ground to the front of
the front blade and from the rear tips of the rear
blades. Front tips should be 1/8” to 1/4” higher than
the rear tips. If not, proceed to step 3.
3. See Figure 47. Loosen the locknut (A) on the arm
assembly. Adjust the jam nut on the arm until the
mower deck is level or the front is 1/8” to 1/4” higher.
