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.

pressure, coolant temperature and fuel level  
gauges, transmission gear indicator and a  
multi-function Contronic monitoring display.  
Located in the fully adjustable steering  
pedestal are the following switches: differential  
lock/unlock, hazard lights, combination turn  
signal, horn and high beam headlight. Heater  
and wiper/washer controls, lighting and  
accessory switches are grouped in the  
operator’s right hand console. This console
