Maintenance Instructions | ADJUSTMENTS |
NOTE: If the engine will not start, check and adjust the neutral safety switch (refer to Neutral Switch Adjustment - Step 6).
5.With the FSC in the neutral position and the en- gine running, the wheels should not move. If a drive tire is moving, the Control Rod on that side is out of adjustment. Adjust that side to achieve neutral. Now both transaxles are in the neutral window.

6.One at a time adjust the left and right Control Rods to find the center of the neutral window. Shorten the rods until the drive tire turns forward then lengthen it until the drive tire turns in reverse (approximately 1 turn). Position the rods halfway between forward and reverse. Tighten the jam nuts.
7.Lower drive tires onto ground.
Full Forward Speed Adjustment - Step 4
1.Move the FSC to the full forward speed position.
2.Raise the body. The set screws in the left and right Transmission Control Arms should not be contacting the locating stud in the transaxle. If they are, back the set screws out until they do not touch.

Straight Tracking Adjustment - Step 5
1.Sit in the seat, start the engine, set throttle at full speed, and with the FSC in the
2.Check for straight ground tracking on a level surface (with hands off the steering levers). Set the FSC at several different speeds and observe if the mower moves in a straight line (use cement joint or other line on ground for reference).
3.If travel is not straight, shorten the control rod of the slow side (adjust in 1/8 turn increments) to match the faster side while maintaining the neu- tral position. If straight tracking and neutral can not be achieved, turn the control rod back to where neutral can be achieved.
4.Lengthen the control rod of the faster side (adjust in 1/8 turn increments) to match the slower side while maintaining the neutral position.
5.If the forward travel is straight throughout the speed range, except at maximum speed - place the FSC in full forward, turn the set screw in the Transmission Control Arm, of the faster side, in until it contacts the hydro stud. (Turning the set screw in slows the wheel.) Turn the set screw in an additional 1/8 turn. Recheck for equal full for- ward speed. Adjust this set screw until equal full forward speed is achieved. Tighten the jam nut.
