SERVICE AND MAINTENANCE
LEVELING THE DECK PITCH/FRONTTOREAR
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. When proper
adjustment is achieved, re-tighten the outer jam nut (a) and
replace the end cap (Figure 35).

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. When proper
adjustment is achieved, re-tighten the outer jam nut (a) to 57
ft-lbs. (77.28 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.
Deck Leveling
If the cutting deck appears to be mowing unevenly, leveling
adjustments can be performed.
WARNING
If the tractor has been recently run, metal surfaces will
be hot and can cause burns to the skin. Let the tractor
cool for at least five minutes Exercise caution to avoid
burns.
LEVELING THE DECK SIDETOSIDE
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’re not, proceed to the next step.
3. Locate the adjustment bolts (a) on the left and right side of
the deck (Figure 34).

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.
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 previously.
5. When proper adjustment is achieved, re-tighten the jam nuts
(b). Tighten to 200 in-lbs (22.5 N-m).
