4. Note the relative position of the control lever to the pivot
bracket, then repeat the previous steps to reposition the
other control lever in approximately the same position.
5. A fine-tuning adjustment can be made if the drive control
levers are not lining up correctly. Be certain that the control
lever knob is secure and loosen the two bolts securing
the control lever adjuster to the lower arm assembly. Pivot
the control lever adjuster forward or rearward to align the
control levers. When the levers are aligned, re-tighten the
bolts to secure the control lever.
Deck Leveling
NOTE: Check the tractor's tire pressure before performing
any deck leveling adjustments. Refer to Tires for information
regarding tire pressure.
WARNING!
Shut the engine off, remove the
ignition key and engage the parking brake before
making adjustments. Protect your hands by using
heavy gloves when handling the blades.
Leveling the Deck (Side-to-Side)
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.
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 7-7.

4. 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.
5. 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 7-8.

6. 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 7-8.
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.
