If the cutting deck appears to be mowing unevenly, a side-to-
side adjustment can be performed. Adjust if necessary as follows:
1.
With the tractor parked on a firm, level surface, place the
deck lift handle 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.
Loosen the lower jam nut on the adjustable lift link
attached to the deck lift arm to lower the deck and tighten
the upper jam nut to secure the deck in place, loosen the
upper jam nut then tighten the lower jam nut to secure the
deck in place. See Figure 6-7.

The deck is properly leveled when both blade tip
measurements are equal.
Leveling the Deck (Front-To-Rear)
NOTE: Check the tractor's tire pressure before performing
any deck leveling adjustments. Refer to Tires for information
regarding tire pressure. Always level the deck side-to-side before
front to rear.
The front of the deck should be between 1⁄4-3⁄8" 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 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 1⁄4" and 3⁄8" less
than the second measurement.
4.
Determine the approximate distance necessary for proper
adjustment and proceed, if necessary.

Using a wrench, raise the front of deck by loosening the
lock nuts to the front of the pivot pin and then tighten the
jam nuts on the back of the pivot pin to raise the front of
the deck and secure in place. See Figure 6-8.

Using a wrench, lower the front of deck by loosening the
jam nuts on the back of the pivot pin and then tighten the
lock nut on the front of the pivot pin to lower the front of
the deck and secure in place. See Figure 6-8.
7.
The deck is properly leveled when the front tip of the blade is
1⁄ 4 " lower than the rear tip. Retighten the hex bolt on the left
rear deck hanger links when proper adjustment is achieved.
Adjusting the Front Gauge Wheels
WARNING!:
Keep hands and feet away from the
discharge opening of the cutting deck.
The front gauge wheels on the mower deck are an anti-scalp
feature, and should not ride on the ground. The front gauge
wheels should be approximately 1⁄4-1⁄2" above the ground when
the deck is set in the desired height setting.
Using the deck lift handle, set the deck in the desired height
setting, then check the gauge wheel distance from the ground
below. If necessary adjust the front gauge wheels as follows:
1.
Visually check the distance between the front gauge
wheels and the ground. If the gauge wheels are near or
touching the ground, they should be raised. If more than
1⁄2" above the ground, they should be lowered.
