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 on the top
26
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 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
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.

Caster Wheels

Check every 200 hours. Check that wheels rotate
freely. Foam filled tires or solid tires will void the
warranty.
To replace, remove the nut and caster bolt. Pull
the wheel out of the yoke and take care with the
spacer. Reinstall in reverse order. Tighten the
caster bolt and torque to 45 ft-lbs (61 Nm).
NOTE: Tire must rotate freely but axle spacers
must not. If wheels do not rotate freely take the
unit to the dealer for service.
