Side-To-Side Leveling
Before making deck leveling adjustments, check the tire
pressure. Refer to "How To Check Tire Pressure". If tires are
properly inflated and mowing is still uneven, adjust side-to-
side deck leveling.
1. Place the unit on a smooth level surface.
2. Turn the engine off and remove the key. Remove the
spark plug wire from the spark plug and secure the wire
away from the plug.
3. Raise the mower deck to the highest cutting position.
4. Place a piece of angle iron, pipe, or similar object under
the rear center of the deck.
5. Lower the mower deck until the rear of the deck is
supported by the object placed under it in the previous
step. (The rear hanger rods (A, Figure 28) should be
loose.)

6. Wearing heavy leather gloves, rotate the blade until the
blade tips are positioned at the right and left sides of
the mower deck. Measure the distance from the blade
tips (A, Figure 28) to the floor (B). If the measurement
(C) is within 1/8" (3mm) from side-to-side, the deck
is considered level. If difference from side-to-side is
greater than 1/8" (3mm), continue with adjustment.
7. If adjustment is needed, slowly turn the eccentric (A,
Figure 29) on the left front lift arm until the blade tips are
within 1/8" (3mm) of each other.

8. Raise the mower deck, and remove the angle iron, pipe,
or similar object.
9. Proceed to check front to rear leveling.
Front-to-Rear Leveling
NOTE: Perform side-to-side leveling first.
1. With the unit on a smooth, level surface, rotate the blade
until the blade tips are at the front and rear of the deck.
2. Measure the distance from the blade tips (A, Figure 28)
to the floor (B). The distance (C) should be the same, or
the rear 1/8" to 1/4" (3 - 6mm) lower than the front. If the
rear blade tip is higher than the front, or is more than
1/4" (6mm) lower than the front, proceed with
adjustment.
3. If adjustment is needed, turn the lock nut (B, Figure 30)
on both left and right hanger rods (A) the same number
of rotations to raise or lower the rear of the deck.

4. Measure the blade tips again.
5. Repeat Steps 2 through 4 until proper leveling is
obtained.
