Abstract:
A steering system for a differential steered self-propelled agricultural windrower, windrower speed and direction controlled by adjusting the pivotal position of rotatable pintel arms to control the output of a pair of tandem-mounted hydraulic drive pumps and provide motive power for the windrower. A control input shaft that is both rotatable and axially moveable manages the relative positioning of the pintel arms. A hydraulic steering motor is operably connected to the input shaft. Rotation of the hydraulic steering motor is managed by a steering control valve attached to a cab-mounted windrower steering wheel.
