Troubleshooting, Adjustment & Service
Mower Adjustments Continued.
WARNING
Cutting Height Adjustment
Before checking mower, shut off PTO and engine.
Allow all moving parts to stop. Remove ignition
key, then disconnect the spark plug wires and
fasten them away from the spark plugs.
Note: To operate the electric cutting height motor, it is
necessary to insert the ignition key and turn it to the on
position. This may be safely done so long as the
spark plug wires have been disconnected as noted
in the WARNING at right. The key should be turned to
off and removed when the step has been completed.
Press the cutting height adjustment switch while observ-
ing the cutting height gauge on the left side of the mower
to adjust the cutting height.

Leveling The Mower
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Tire pressure should be as follows:
A
•
Front: 12-15 psi
•
Rear: 6-8 psi

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"
or less, proceed to Front To Back Leveling.

See Figure 47. Loosen the outside nut (A) then turn
the eccentric nut (B) to raise or lower the left side of
the deck. Repeat on the right side of the deck. When
the mower deck is level, hold the eccentric nut while
tightening the outside nut.
FRONT TO BACK LEVELING
1.
2.
Arrange the blades so they face front-to-back.
Measure the distance from the ground to the front
and rear tips of each blade. The measurement should
be equal for both blades. Front tips should be 1/8” to
1/4”
higher that the rear tips. If not, proceed to step 3.
3.
Loosen the two rear jam nuts on both both arm
assemblies (see Figure 48). Adjust the jam nuts on
both arms until the mower deck is level or the front is
1/8”
to 1/4” higher.
