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.
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.
