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
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" (1.174 - 9.525) 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" (1.174
- 9.525) 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 may be required to
get the desired cut.
Anti-scalp Rollers
Anti-scalp rollers are properly adjusted when they
are slightly off of the ground when the deck is at
the desired cutting height. Anti-scalp rollers keep
the deck in the proper position to help prevent
scalping in most terrain conditions. Do not adjust
the rollers to support the deck.
IMPORTANT INFORMATION Adjust anti-scalp
rollers with the mower on a flat level surface.
To avoid deck damage, the anti-scalp rollers
must not be adjusted to support the deck.
Anti-scalp rollers can be set in three positions.
• Upper 1" to 2-1/2" (25 mm - 63.5 mm) grass
• Middle 2-1/2" to 4" (63.5 mm - 101.6 mm) grass
• Lower 4" to 5" (101 mm - 127 mm) grass
The rollers must be approximately 1/4" from
ground. Do not adjust the rollers to support the
deck.
Tire Pressures
All tires must be at 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION DO NOT add
a tire liner or foam fill material to the tires.
Excessive loads created by foam filled tires will
cause premature failures.
Only use O.E.M. specified tires.
