MOWER ADJUSTMENTS
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:
• Front: 12 - 15 psi (82-103 kPa)
• Rear: 10 - 12 psi (56-82 kPa)
SIDE-TO-SIDE ADJUSTMENT
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 high-cut position. Arrange the
mower blades so that they are pointing from side-to-
side (Figure 31).
4. See Figure 31. Measure the distance between the
outside tips of each blade and the ground. If there is
more than 1/8" (3mm) difference between the mea-
surements on each side, proceed to step 5. If the dif-
ference is 1/8" (3mm) or less, proceed to step 6.
5. See Figure 32. Loosen the outside nut (A) and tap-
tite screw (C), then turn the eccentric nut (B) to raise
or lower the left side of the deck. When the mower
deck is level, hold the eccentric nut while tightening
the outside nut. Tighten the taptite screw (C).
FRONT-TO-BACK ADJUSTMENT
1. Arrange the blades so they face front-to-back (Figure
33).
2. See Figure 33. 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 equal to rear tips or within 1/8" higher.
If not, proceed to step 8.
WARNING
Before checking mower, shut off PTO and
engine. Allow all moving parts to stop. Remove
ignition key, then disconnect the spark plug wire
and fasten it away from the spark plug.
