Patent ID: 10625770

Abstract:
Automatic steering and four-wheel steering are configured on an agricultural machine so that when automatic steering is enabled, a control system selectively activates and deactivates four-wheel steering depending on sensed turning or non-turning states of the machine. When automatic steering is enabled, the machine can automatically steer, such as according to a prescription map. In straightaway paths, corresponding to non-turning states, the control system can activate two-wheel steering. However, in the headlands of fields, corresponding to turning states, the control system can activate four-wheel steering. Such turning states can be determined based on the machines location on the map. Alternatively, such turning states can be determined based on sensed turning of the wheels. When an operator takes control of steering, such as by turning the steering wheel, automatic steering can disable, and the control system can activate four-wheel steering, to provide an optimum state for turning in the headlands of fields.
