MOWER ADJUSTMENTS
Cutting Height Adjustment
The cutting height adjustment lever (A, Figure 37) con-
trols the mower cutting height. Push the button to
release the lever. Move the lever back to raise the deck
and forward to lower it.
Leveling The Mower
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as speci-
fied in Checking Tire Pressure.
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. Check for bent blades and replace if necessary.
3. Place the mower in mid-cut position. Arrange the
outside mower blades so that they are pointing from
side-to-side.
4. 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 5. If the difference is 1/8”
(3mm) or less, proceed to step 6.
5. See Figure 36. Support the mower deck, remove the
hair pin clip (A), and thread the trunnion (B) up or
down the J-hook (C) to raise or lower the left or right
side of the mower deck. Reinstall the trunnion in the
mower lift bar and secure using the hair pin clip (A).
FRONT-TO-BACK LEVELING
6. Arrange the blades so they face front-to-back.
7. Measure the distance from the ground to the front tip
of the center blade, and from the ground to rear tips
of left-hand and right-hand blades.
Front tip of the center blade should be 1/4" (6mm)
higher than rear tips of left-hand and right-hand
blades. If not, proceed with steps 8 - 9.
8. To raise front of mower deck, loosen front nut (B) and
turn rear nut (A, Figure 37) against bracket. To lower
front of mower deck, loosen rear nut (A) and the
bracket will move backwards to lengthen rod.
9. Re-check the blade measurement then tighten the
front nut (B) against the bracket to secure.
