Operating modes
All Wheel Drive or Tandem Drive
• On-Off Selection
• Creep Mode - Hydrostatic front wheel drive
only for optimum control and manouverability
while fine grading.
Two 3" (76 mm) diameter wheel lean cylinders
and lock valve are standard equipment.
• Manual Mode - Allows the operator to match
front wheel agression setting to specific
applications.
All Wheel Drive
The Volvo high torque All Wheel Drive System
operates in forward gears 1-7 and reverse
gears 1-4. The operator may shift from 7th
AWD into 8th and back to 7th AWD at any
time for maximum high speed performance.
The Volvo high torque All Wheel Drive System
incorporates two variable displacement, closed
loop piston pumps. The Volvo AWD design
automatically adjusts hydraulic flow and
pressure to the drive system to match tandem
wheel speeds in all tractive conditions. Each
front wheel is independently powered by a 2
speed motor. Each motor is controlled by its
own speed sensor and pump. The All Wheel
Drive system is controlled by the operator
through a positive On/Off switch as well as a
16 position variable aggression dial. The front
wheel speed sensors will always match front
wheel speed to tandem wheels speed relative
to the level of aggression selected by the
operator. This provides optimum job matching
AWD features
• Maximum startup torque
• Power maintained in either direction
• Smooth operation in low speeds
• Maintains front wheel agression in turns
• One speed sensor at each front wheel
• Hydrostatic Creep Mode feature
In addition, the Volvo system provides the
operator with the ability to fine grade in Creep
Mode using only hydrostatic front wheel drive.
The Volvo high torque All Wheel Drive System
offers infinite speed control below 2 mph (3,2
km/h) for fine grading as well as a top speed
of 20.2 mph (32,5 km/h) for snow plowing.
The AWD controller is integral with the
electronic 8400 transmission controller,
thereby supplying the same diagnostic
features found in the Volvo 8400 transmission.
