USING THE TRANSMISSION BYPASS RODS

USING THE TRANSMISSION BYPASS RODS

If for any reason the tractor will not drive or you wish to move the tractor, the two hydrostatic transmis- sions are equipped with bypass rod that will allow you to manually move the tractor short distances.

WARNING: Do not tow the tractor, even with the bypass rod engaged. Serious transmission damage will result from doing so.

From just in front of the two rear tires, locate the transmission bypass rods. See Figure 23.

Pull one rod toward the front of the tractor until the flange on the rod is forward of the keyhole slot in the frame assembly.

Lower the bypass rod into the keyhole slot and release so the rod flange is against the front of the frame bracket.

Repeat the above procedure to engage the other bypass rod.

Figure 23

After moving the tractor, disengage both bypass rods. Lift the rod and guide the flange of the rod back through the larger circular opening of the keyhole, then release the rod.

IMPORTANT: The tractor will not drive with the bypass rods in the engage position.

TRACTOR CREEPING

Creeping is the slight forward or backward movement of the tractor when the engine is running at high idle and the drive control levers are opened out in the neutral position.

If after operating the tractor for some time, it begins to creep while in the neutral position, adjust the transmission control rods as follows.

Place the front of the tractor against an immovable object (e.g. wall, post, etc.).

Jack up the rear of the tractor so that both rear wheels are approximately one inch of the ground.

With the engine running at high idle and the drive control levers opened out in the neutral position, and the parking brake disengaged, check the rear wheels for rotation.

If only one wheel is rotating, locate the transmis- sion control rod beneath the frame at the front of the rear tire. If both wheels rotate, locate both control rods. See Figure 24.

Remove the internal cotter pin securing the ferrule to the transmission control arm and withdraw the ferrule. Wheel rotation should stop. If it does not, contact your White Outdoor dealer.

If the rotation stops, adjust the ferrule up or down the control rod as necessary to align with the hole in the transmission control arm. Re-insert the ferrule into the hole in the control arm and secure with the internal cotter pin.

If necessary, repeat the previous two steps to adjust the other transmission control rod.

Lower the tractor and remove the jack.
