TRANSAXLE TROUBLESHOOTING CHECKLIST Possible Cause Corrective Action UNIT OPERATES IN ONE DIRECTION ONLY Control linkage bent or out of adjustment. Drive belt slipping or pulley damaged. Repair or replace linkage. Repair or replace drive belt or pulley. VEHICLE DOES NOT DRIVE/TRACK STRAIGHT Vehicle tires improperly inflated. Control linkage bent, loose, or out of adjustment. Bypass partially engaged. Inflate to recommended pressure. Check tire diameters are approximately equal, side-to-side.
TRANSAXLE Fluids Engine oil with a minimum rating of 55 SUS at 212 F° and an API classification of SH/CD is recommended. A 20W-50 engine oil has been selected for use by the factory and is recommended for normal operating temperatures. 0702-0501 Check oil level when cold. To check the transaxle fluid level, remove the vent. Oil level should be 1-7/8” - 2-3/16” (4.8 cm - 5.56 cm) from the top of the vent port. The oil level can only be checked when the transaxle is removed from the machine.
TRANSAXLE Remove and Replace Transaxle Disconnect the battery. 0702-0408 Close the fuel shut-off. 5 0702-0409 Raise the rear of the unit and support it with jack stands.
TRANSAXLE Remove the clip that secures the vent hose to the chassis. 0702-0506 If necessary, engage the parking brake to facilitate wheel removal. 5 0702-0507 Remove the wheel assembly.
TRANSAXLE Remove the parking brake link from the brake arm. 0702-0509 Disconnect the motion control link from the transaxle. 5 0702-0510 Remove the hairpin cotter and washer from the bypass valve lever. Leave the rod in place.
TRANSAXLE Move the idler pulley to lessen the tension on the traction drive belt and slip the belt up off the engine drive pulley. 0702-0419 Remove the belt from the transaxle being removed. 5 0702-0512 Loosen and remove the 6 bolts and washer between both transaxles. Remove the hydro lower plate. Note the orientation of the hydro lower plate. It must be reinstalled with the lip facing down, toward the front.
TRANSAXLE Support the transaxle with a jack while removing the last bolts. 0702-0514 Guide the transaxle as it is lowered. Make sure the cooling fan and vent hose clear the chassis.
TRANSAXLE Reassembly IMPORTANT: Before installing a new transaxle, check the oil level and check the torque on the nut retaining the input pulley. Torque to 30 - 35 ft. lbs. (40.7 N·m - 47.5 N·m). 0702-0516 Use a jack to lift the transaxle into the chassis. Carefully guide it into position so that the cooling fan does not catch on the chassis and the bypass rod is properly positioned in the lever. Insert the vent hose through the slot provided for it in the frame.
TRANSAXLE Place the traction belt on the pulley. Check for correct belt routing. (A) (B) (C) (D) Engine Pulley Idler Pulley Right Hydro Left Hydro 1s-0802 Install the hairpin cotter pin and washer on the bypass valve lever. 5 0702-0511 Reinstall the motion control link.
TRANSAXLE NOTE: The length of the link is set at the factory and should not normally require adjustment in the field. If the link has been tampered with, the distance between bolt centers is: • Left side 3.6” (9.14 cm) • Right side 3.1” (7.9 cm) 0702-0517 Install the parking brake linkage. 5 0702-0509 Replace the wheel assembly.
TRANSAXLE Secure the vent hose to the chassis. 0702-0506 Recheck to make sure the brake arm clears the teeth of the brake cog when the park brake is disengaged.
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). 5 0702-0520 3. If adjustment is needed: A. Lift the seat and located the adjusters. Loosen the jam nut on the yoke.
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. It should return to the neutral slot. D. Before starting the unit, follow the procedures on 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. 0702-0516 Air creates inefficiency because its compression and expansion rate is higher than that of the oil normally approved for use in hydrostatic drive systems.
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. When the transaxle moves forward and reverse at normal speed, purging is complete.
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. Warm the transaxle fluid by running for at least 10 minutes. 5 0702-0505 5. Unplug the seat switch and temporarily connect a jumper wire across the plug connector.
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. 5 0702-0527 8. If necessary, loosen the jam nuts (A) and turn the control rod until the wheel stops between forward and reverse. In some cases, you may have a slight creep in reverse. When you lower the unit to the ground, it should stop.
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. The wheels should not creep in the forward direction when the control handles are in the neutral lock out position. 0702-0529 5 10. Run the engine at full throttle.
TRANSAXLE 12. Remove the jumper wire on the seat switch and plug the switch into the harness. Lower the unit to the ground.
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. NOTE: Ground surface should be level when checking the tracking. 0702-0525 1. Check the tire pressure in each tire. 13 psi (90 kPa) rear, 35 psi (241 kPa) front.
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. 3. After attempting any tracking change with the unit, make sure it is still neutralized.
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. Tighten the bolts after adjustment.

ELECTRICAL SYSTEMS SAFETY INTERLOCK SYSTEM B A B C Interlock Components The safety interlock system consists of a series of switches which prevent the unit from starting unless: • The parking brake is engaged. • The PTO switch is in the off position. • The motion control handles are in the neutral lockout position. There is also a kill relay which de-energizes and stops the engine if the motion control handles are pulled in while the parking brake is engaged.
ELECTRICAL SYSTEMS The seat switch is closed when the operator is on the seat.
ELECTRICAL SYSTEMS Electrical Components The PTO switch routes power to the electric clutch when in the on position and to the kill relay through the brake switch when in the off position. 0702-0805 The start solenoid connects the battery to the starter motor. 0702-0812 8 The kill relay connects the engine magneto to ground whenever it is not energized.
ELECTRICAL SYSTEMS There are two fuses in the system: • The 30 amp fuse is in the main power supply from the battery. • The 25 amp fuse is in the battery charge circuit.
ELECTRICAL SYSTEMS Electric Clutch The TimeCutter Z is equipped with a Warner electric clutch. The clutch is not serviceable. There are two tests used to determine if the clutch is faulty. 0702-0809 Measure the resistance across the clutch plug terminals. The resistance should be 2.9 ohms ± 20%. 0702-0810 8 Connect a 12 volt power source across the clutch plug. The clutch should click when it engages. The clutch uses a magnetic brake to stop the mower blades when disengaged.
