the flat washer and into the lower arm. Tighten the hex
screw until snug.
4. Insert the hex screw through the flat washer and through
the control lever slot and the lower arm. Do not tighten now.
5. If you are going to adjust the control levers forward or rearward,
proceed to the next step. If not, fully tighten the hex screw.
To adjust the drive control levers forward/rearward, proceed as
follows:
1. If not already loose, loosen the hex screw and rotate the
control lever either forward or rearward to the desired
position. See Figure 6-4.
NOTE: If the control lever is too tight to move, slightly
loosen the hex screw at the bottom of the control lever.
2. Tighten the hex screw to fix the control lever in the
adjusted position
3. Repeat the above procedure to adjust the other control
lever into the same position. Adjust so that both levers are
even with each other when in the neutral position.
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 6-5.

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.
