OPERATION
HYDRAULIC WEIGHT TRANSFER -
TRACTION BOOST
The integrated hydraulic weight transfer traction
boost system transfers weight from the attachment
back to the front wheels of the tractor. Transferring
weight from the attachment to the tractor increases
traction control, improves hillside maneuverability,
and lessens the attachments contact resistance
when in contact with the ground.
The hydraulic weight transfer traction boost system
is automatically engaged when the front lift control
lever is moved into the Float position. The hydraulic
weight transfer traction boost system is automatically
disabled when the front lift control lever is moved out
of the Float position.
The operator can select infinite transfer rates by
adjusting the pressure control valve between 0 psi,
no weight transfer, to 400 psi, maximum weight
transfer.
Set the weight transfer 0 psi when attaching or
detaching any attachment.
HIGH-LOW RANGE SELECTION
The units are shipped with the transaxle gear range
selector in HIGH (H) range. This range selection is
recommended for most of the operating tasks. If
slower speeds and more responsive F-R control is
needed, use LOW (L) range selection.
Do not use excessive force to shift between high and
low range. Damage to shift mechanism.

INSTRUCTIONS FOR TRANSAXLE
RANGE SELECTION
Do not attempt to select ranges on slopes or
when the unit is traveling. Select ranges only
when unit is stopped on level surfaces.
1. Stop the unit on a level surface and set PARKING
BRAKE.
2. To move the transaxle range selector lever from
high (H) to low (L), grasp the lever and pull
outwards just so it clears the stop on the lever
until the lever rests on top of the center stop.
NOTE:
The range selection lever controls the
disengagement and reengagement of the gears
in both the front and rear transaxle. To promote
easy shifting between high and low ranges,
rocking the tractor back and forth OR turning
the steering wheel side to side can help align
gears for reengagement in both front and rear
transaxles.
3. Reverse the procedure to go from low (L) to high
(H).
NOTE:
The lever should rest against the center stop
as shown. If not, refer to the "Hi/Low Range Stop
Plate Adjustment"
EMERGENCY TOWING INSTRUCTIONS
FOR A STALLED UNIT
1. Both transaxles must be in neutral before moving
a stalled unit. Neutral position is between HIGH
(H) and LOW (L) range position.
2. Move the transaxle range selector lever to the
Neutral (N) position.
Failure to shift transaxles into "Neutral" will
cause serious damage to the hydrostatic
system.
With the transaxles in neutral and the parking brake
disengaged, the tractor can freewheel. Use extreme
caution when towing or pushing the tractor, steering
may not function. Engage the parking brake to slow
or stop the unit.
