  • Auxiliary axle for an agricultural harvester during road transport
    Patent number: 9125343
    Abstract: An agricultural harvester includes a chassis and a feeder housing pivotally mounted to the chassis. The agricultural harvester is characterized in that an axle assembly is pivotally mounted to the feeder housing. A hydraulic actuator is coupled with the axle assembly for pivotally moving the axle assembly in upward and downward directions from the feeder housing. A road mode switch provides a first output signal indicative of a field mode and a second output signal indicative of a road mode. A controller is coupled with the road mode switch and the hydraulic actuator. The controller receives the second output signal from the road mode switch and controls the hydraulic actuator, whereby the hydraulic actuator provides a substantially constant down force between the axle assembly and a ground surface.
