ALL-WHEEL DRIVE (AWD)
0005
All-wheel drive (AWD) allows the operator to choose which wheels propel the machine and how fast the front
wheels turn in relation to the rear wheels. All-Wheel Drive is controlled by an AWD Mode Switch (CREEP {turtle},
OFF {circle}, and MANUAL {hand} positions) and an AWD Control Dial (minus, circle, and plus signs) (Figure 18).
With AWD off, only tandem wheels propel the machine. Machine speed is controlled by the accelerator
pedal.
When AWD is activated and CREEP mode engaged, only the front tires propel the machine. Front wheel
speed (zero to 5 mph {8km/h}) is controlled by the AWD Control Dial. Creep mode provides very precise
speed control when fine blading around obstacles, and prevents rear wheels from damaging finished sur-
faces due to driving force of rear wheels.
When AWD is activated and MANUAL mode engaged, all six wheels propel the machine. Front wheel
speed (98 to 120 percent of rear wheel speed) is controlled by the AWD Control Dial. The center detent is
100% or 1:1 front wheel speed to rear wheel speed. Higher aggression (101% to 120%) allows more
power to be transmitted through the front wheels, providing better steering control in low traction conditions
and when bank sloping when trying to keep front wheels on slope while rear wheels are on level ground.

1. Before turning AWD Mode switch to CREEP position, the machine must meet the following conditions:
a. Machine stopped (zero ground speed).
b. Engine running.
c.
Parking brake switch set to ENGAGED position.
d. Transmission control switch set to NEUTRAL position.
2. Turn AWD Mode switch to CREEP position.
a. Rear transmission will be neutralized.
b. AWD indicator will illuminate.
3. Disengage parking brake (WP 0004).
4. Move Transmission Control switch to desired direction (FORWARD or REVERSE). When in CREEP mode,
power is supplied only to the front wheels.
