MAINTENANCE
Adjusting the Mower Deck
Leveling Deck
Adjust the deck while the mower is on a level
surface. Make sure the tires are inflated to the
correct pressure. See Tire Pressures in the
Maintenance section. If tires are under or over
inflated, the deck cannot be correctly adjusted.
Faulty mower deck adjustments will cause an
uneven mowing result.
Four slots control the height and pitch of the
mower deck. Adjust the deck slightly higher in the
rear.
NOTE: To insure precision in the leveling
procedure, the mower deck drive belt must be
installed before leveling the deck.
1. Wear heavy gloves. Turn each outer blade tip
to align with the deck side to side.
2. Measure from the floor surface up to the
bottom of the blade tip on the discharge side
of the mower deck. Record this measurement.
Move to the opposite side; check that
measurement is the same. If adjustment
is required, loosen the locknut on the top
of the rear links and adjust until both side
to side measurements are equal. Retain
measurement.

3. Turn both outer blades to align with the deck
front-to-rear. Reposition the front mounting
bolts up or down until the rear blade tips are
positioned 3.2 mm (1/8") to 9.5 mm (3/8")
higher in the rear than the front blade tips.
4. Confirm measurements once again. The blade
tip height must be equal side-to-side. In the
rear, blade tips must be 3.2 mm (1/8") to 9.5
mm (3/8") higher than the front measurement.
In the front, blade tips must be equal from
side-to-side.
NOTE: This will place the mower deck in a
standard measurement position. Depending on
the type of grass being mowed or environmental
conditions, more adjustments can be necessary
to get the desired cut.
