Abstract:
A steering system is provided for an agricultural vehicle having steerable wheels of a first wheel set, first and second steerable wheels of a second wheel set, and a steering input device configured to receive a manual steering input for the wheels of the first wheel set. The steering system includes first and second hydraulic steering devices coupled to the first and second steerable wheels of the second wheel set; a valve assembly configured to hydraulically control the hydraulic steering devices to steer the wheels of the second wheel set; and a controller configured to determine steering commands and provide the steering commands to the valve assembly. In a rear stability mode, the valve assembly is configured to selectively dampen fluid flow between the first and second hydraulic steering devices.

Claim (Index 1):
A steering system for an agricultural vehicle having one or more steerable wheels of a first wheel set, at least first and second steerable wheels of a second wheel set, and a steering input device configured to receive a manual steering input for the one or more steerable wheels of the first wheel set, the steering system comprising:\n a first hydraulic steering device coupled to the first steerable wheel of the second wheel set; a second hydraulic steering device coupled to the second steerable wheel of the second wheel set; a valve assembly configured to hydraulically control the first and second hydraulic steering devices to steer the first and second steerable wheels of the second wheel set; and a controller configured to determine second wheel set steering commands and provide the second wheel set steering commands to the valve assembly; wherein the valve assembly hydraulically controls the first and second hydraulic steering devices based upon, at least in part, the second wheel set steering commands from the controller; wherein, in a steering assist mode, the controller determines the second wheel set steering commands based upon, at least in part, the manual steering input; wherein, in an automated steering mode, the controller determines the second wheel set steering commands based upon, at least in part, a target path of the agricultural vehicle that is determined independently of the manual steering input; and wherein, in a stability mode, the valve assembly is configured to selectively dampen fluid flow between the first and second hydraulic steering devices.
