Abstract
An agricultural harvester rear axle arrangement for an agricultural harvester (10) having a body (12), the arrangement comprising left and right rear wheels (18, 20); means for supporting the wheels for rotation about a generally vertical steering axis (38, 40, 78, 94) and for supporting the wheels for extension and retraction from the body of the combine (26, 28, 30, 90); actuator means for steering the wheels (38, 40, 70, 72, 94) and for extending and retracting the wheels (34, 36, 70, 72); an electronic controller (50) coupled to the actuator means to steer, extend and retract the wheels.

An agricultural harvester rear axle arrangement for an agricultural harvester (10) having a body (12), the arrangement comprising left and right rear wheels (18, 20);
- means for supporting the wheels for rotation about a generally vertical steering axis (38, 40, 78, 94) and for supporting the wheels for extension and retraction from the body of the combine (26, 28, 30, 90);
- actuator means for steering the wheels (38, 40, 70, 72, 94) and for extending and retracting the wheels (34, 36, 70, 72);
- an electronic controller (50) coupled to the actuator means to steer, extend and retract the wheels.
A method for operating an agricultural harvester rear axle having two steerable rear wheels (18, 20), the method comprising the steps of electronically monitoring an operator input device (54) that provides a signal indicative of a desired steering angle in a first mode of operation;
- calculating a desired degree of extension for the desired steering angle based at least, upon the signal;
- and substantially simultaneously steering the rear wheels (18, 20) to the desired angle and extending the wheels (18, 20) to the desired degree of extension.
