SERVICE AND MAINTENANCE
3. Position the pedal to the optimal position based on operator
preference. See Figure 38.
Figure 38
4. Re-install the hardware previously removed and torque the
nut to 28-35 ft-lbs (38-47 N-m). See Figure 37.
DECK LEVELING
If the cutting deck appears to be mowing unevenly, leveling
adjustments can be performed.
WARNING
If the tractor has been recently run, the engine, muffler,
and surrounding metal surfaces will be very hot and can
cause burns to the skin. Let the engine cool for at least five
minutes. Exercise caution to avoid burns.
WARNING
Tractor blades are sharp. Wrap the blade or wear gloves, and
use extra caution when servicing them.
LEVELING THE DECK SIDETOSIDE
1. Place the deck lift handle or deck lift knob in a middle
mowing position and rotate both outside blades so that they
are perpendicular with the tractor.
2. Measure the distance from the outside of the left blade tip
to the ground and the distance from the outside of the right
blade tip to the ground. Both measurements taken should be
equal. If they are not, proceed to the next step.
3. Locate the adjustment bolts (a) on the left and right side of
the deck. See Figure 39.
4. Loosen, but do not remove, the jam nuts (b) on the
adjustment bolt. Adjust either the right or left adjustment
bolt up or down as necessary until the side-to-side heights
are equal. See Figure 39.

Figure 39
NOTE: Continue to check the front-to-back leveling as
you make the side-to-side adjustment as the side-to-side
adjustment can affect the front-to-back level. If necessary,
adjust front-to-back as instructed in the next section.
5. When proper adjustment is achieved, re-tighten the jam
nuts (b). Tighten to 57 ft-lbs (77 N-m). See Figure 39.
LEVELING THE DECK PITCH/FRONTTOREAR
The front of the deck should be between 1⁄16-1⁄4” (2-6 mm)
lower than the rear of the deck. Adjust if necessary as follows:
1. Park the tractor on a firm, level surface and place the deck lift
handle or deck lift knob in a middle position.
2. Rotate the blade nearest the discharge chute so that it is
parallel with the tractor.
3. Measure the distance from the front of the blade tip to the
ground and the rear of the blade tip to the ground. The first
measurement taken should be between 1⁄16-1⁄4” (2-6 mm)
less than the second measurement.
4. Determine the approximate distance necessary for proper
adjustment and proceed, if necessary.
5. To raise the front of the deck, remove the end cap, loosen
the outer jam nut (a) then tighten (thread inward) the inner
nut (b) against the front hanger bracket. See Figure 40. When
proper adjustment is achieved, re-tighten the outer jam nut
(a) to 57 ft-lbs (77 N-m) and replace the end cap.

6. To lower the front of the deck, remove the end cap, loosen
the outer jam nut (a) then loosen (thread outward) the inner
nut (b), away from the front hanger bracket. See Figure 40.
When proper adjustment is achieved, re-tighten the outer
jam nut (a) to 57 ft-lbs (77 N-m) and replace the end cap.
ADJUSTING THE DECK WHEELS
WARNING
Keep hands and feet away from the discharge opening of the
cutting deck.
NOTE: The deck wheels are an anti-scalp feature of the deck and
are not designed to support the weight of the cutting deck. The
deck wheels should be approximately 1⁄4-1⁄2” (6.35-12.7 mm)
above the ground when the deck is set in the desired height
setting. To adjust the deck wheels, see the Assembly section
forinstructions.
LAPBAR DRIVE CONTROL LEVER STOP ADJUSTMENT
When the lapbar drive control levers are both fully extended
forward to the full-speed position and the tractor drifts left
or right, the lapbar drive control lever stop adjustment can be
adjusted to sync the wheel speeds. To perform the adjustment,
proceed as follows:
