WHEEL DRIVE SYSTEM
HYDROBACK DRIVE PEDAL NEUTRAL ADJUSTMENT
When servicing the hydrostatic drive system, always check for any machine creeping (movement) in the neutral position. The machine must not
move in either Fwd or Rev after the drive pedal is released. If machine creeping is experienced the neutral position of the hydro back must be adjusted.
WARNING!
Use jack stands to support the machine when setting the neutral drive pedal adjustment.
1 Block the front wheels. Jack up machine until the rear drive wheel is off the floor. Place supports at the rear corners of the machine.
2 Remove the right side engine cover to access the hydroback adjustment bracket.
3 See Figure 2. Loosen the two Lock Screws (I) that secure the moveable cable mount Bracket (J) to the chassis.
4 Start the engine and observe the direction of the drive wheel rotation. Next turn the adjustment Screw (K) clockwise (CW) or counterclockwise
(CCW) to move the cable mounting bracket (in or out) enough to stop any wheel movement. The pump arm is now in neutral, tighten the two
lock screws to secure the neutral pump arm setting.
5 Test the neutral adjustment by activating the drive pedal in both FWD & REV to confirm proper wheel motor control. Readjust again if neutral
setting is not repeatable. Replace the hydroback and or its linkage if a neutral adjustment can not be obtained.
6 Turn the engine off then check to see that it will restart. If engine will not start the pedal sense switch is probably out of its neutral (dead band)
setting and needs to be reprogrammed. See the sense switch replacement manual section for programming instructions.
HYDROBACK CABLE ASSEMBLY REMOVAL
1 Disconnect at both cable ends (foot pedal and pump arm) the Clevis (L) and Rod End (M).
2 Loosen both cable anchor connector nuts.
3 Slide hydroback assembly from its chassis and cable adjustment mounting brackets.
4 After installing a new cable/hydroback see the hydroback pedal neutral adjustment instructions.
