An autoguidance interface for a hydraulic steering system for a differential steered self-propelled agricultural windrower, windrower speed and direction controlled by adjustment to a control input shaft to control the output of a pair of tandem-mounted hydraulic drive pumps and provide motive power for the windrower. The control input shaft is rotatable and axially moveable. A hydraulic steering motor is operably connected to the input shaft to effect control input shaft rotation. Rotation of the hydraulic steering motor is selectively managed by a steering control valve attached to a cab-mounted windrower steering wheel or a proportional steering valve managed by the autoguidance system. A selector valve controls the active steering input. An emergency disengagement positions the selector valve to restore manual control by the steering wheel.
