(40.7 N·m - 47.5 N·m). 0702-0516 Use a jack to lift the transaxle into the chassis.

  • Page 58: Control Handle-Return To Neutral Adjustment

    TRANSAXLE Control Handle-Return To Neutral Adjustment 1. With the engine off, move the directional control handles to the reverse position. 0702-0519 2. Let the handles go. They should return to the neutral position, which means the handle should line up with the neutral slot (neutral lockout position).
  • Page 59 TRANSAXLE B. Turn the top bolt head until the directional control handle is lined up with the neutral slot (Neutral Lockout Position). 0702-0522 C. Tighten the jam nut and then test the directional control handle by pulling the handle in reverse and then let the handle go.

  • Page 60: Purging The System

    TRANSAXLE Purging the System Due to the effects air has on efficiency in hydrostatic drive applications, it is critical that it be purged from the system. These purge procedures should be implemented any time a hydrostatic system has been opened to facilitate maintenance or any additional oil has been added to the system.
  • Page 61 TRANSAXLE 2. Place the bypass valves in the closed position (operating). With the engine running, slowly move the directional control handles through the forward and reverse directions (5 to 6 times). 3. It may be necessary to repeat steps 1 and 2 until all the air is completely purged from the system.

  • Page 62: Neutral Adjustment

    TRANSAXLE Neutral Adjustment 1. If the unit creeps in neutral, it will be necessary to make an adjustment to the transaxle. 2. Operate the unit to determine which transaxle needs adjustment. 0702-0525 3. Raise the unit and place it on jack stands. 4.
  • Page 63 TRANSAXLE 6. Place the directional control handles in the neutral lockout position. Start the engine and run at half throttle. 0702-0526 7. The rear traction wheels should remain stationary or creep slightly in reverse. 0702-0527 8. If necessary, loosen the jam nuts (A) and turn the control rod until the wheel stops between forward and reverse.
  • Page 64 TRANSAXLE 9. After you have adjusted the rods, move the directional control handle in reverse position, then let go of the handles. The handles should move to the neutral position and the drive wheels should remain stationary, or have a very slight amount of creep in reverse.
  • Page 65 TRANSAXLE 12. Remove the jumper wire on the seat switch and plug the switch into the harness. Lower the unit to the ground. 0702-0532 TimeCutter™ Z Service Manual 5 - 21...

  • Page 66: Tracking Adjustment

    TRANSAXLE Tracking Adjustment When operating the unit in forward, it is not unusual for the unit to track slightly right or left when going for a distance. This is because of the different tolerances between two different hydrostatic pumps. If the tracking deviation is large, check the following.
  • Page 67 TRANSAXLE NOTE: All of the control linkage is set up for forward motion. It is not unusual to have a large tracking error when going a distance in reverse. Do not try to adjust reverse tracking. If you do, it will misadjust the forward linkage.

  • Page 68: Control Handle Adjustment

    TRANSAXLE Control Handle Adjustment If the directional control handles do not line up with each other, they require adjustment. 1. Loosen the bolts attaching the handles to the control linkage. 0702-0534 2. Adjust the position of the handles so that they are aligned.
