Adjustments
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.
Adjusting RH & LH Drive Control Levers
The RH and LH drive control levers can be adjusted up or down and fore-and-aft for
the comfort of the operator. The drive control levers can be placed in either of two
height positions, and/or can be moved forward or rearward within the range of the
slot in each control lever mounting bracket.
To adjust the drive control lever height, proceed as follows:
1.
Remove the flange lock nut, flat washer, and hex screw securing the lever to
the pivot bracket.
2.
While supporting the control lever to keep it from falling, remove the hex
insert flange lock nut and shoulder screw from the bottom of the control
lever and pivot bracket. Refer to Figure 35.

Reposition the control lever to align with the other set of holes in the pivot
bracket and insert the shoulder screw removed earlier. Fasten with the hex
insert flange lock nut and tighten until snug.
4.
Insert the hex screw with washer through the control lever slot and the pivot
bracket. Thread the flange lock nut onto the screw, but 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 flange lock nut.

To adjust the drive control levers forward or rearward, proceed as follows:
1.
If not already loose, loosen the flange lock nut and rotate the control lever
either forward or rearward to the desired position. See Figure 35.
NOTE: If the control lever is too tight to move, slightly loosen the hex insert
flange lock nut and shoulder screw at the bottom of the control lever.
2.
Tighten the flange lock nut 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.
Leveling the Mower Deck
When correctly adjusted the mower deck should be level side to side, and the front
of the deck should be approximately 1⁄ 4 " lower than the rear of deck.
NOTE: Check the riding mower's tire pressure before performing any deck
leveling adjustments. See the tire side wall for proper inflation pressures.
Side to Side Leveling
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 riding mower parked on a firm, level surface, place the deck lift
handle in the top notch (highest position) and rotate both blades so that
they are perpendicular to the riding mower frame.
2.
Lower the deck to the middle height position.
3.
Measure the distance from the outside left blade tip to the ground and the
distance from the outside right blade tip to the ground. The measurements
should be equal. If they're not, proceed to the next step.
4.
Comparing the two measurements, determine whether the right side of the
deck must be raised or lowered.
5.
Loosen, but do not remove, the hex screw on the left deck hanger bracket.
Refer to Figure 36.
