Adjusting the Mower Deck

Check the tire pressure before adjustment of the
mower deck. See Tire Pressures in Maintenance
section. Faulty mower deck adjustments will
cause an uneven mowing result.
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
Maintenance section. If tires are under or over
inflated, the deck cannot be properly 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 prior to 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 and adjust bolt
up 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 rear mounting
bolts up or down until the rear blade tips are
positioned 1/8" to 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 1/8" to 3/8" higher
