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 14):
The steering method of  claim 13 ,\n wherein the valve assembly includes: first and second pilot valves configured to receive the second wheel set steering commands from the controller; first and second main spool valves arranged in parallel between a pump and the first and second hydraulic steering devices, wherein the first and second main spool valves are controlled by the first and second pilot valves, respectively; and a blocker valve disposed between the pump and the first and second main spool valves; and wherein the steering method further comprises: generating in the steering assist mode and the automated steering mode, the second wheel set steering commands such that the blocker valve is opened to direct pressurized flow from the pump into the valve assembly; and generating in the stability mode, the second wheel set steering commands such that the blocker valve is closed to prevent pressurized flow from the pump into the valve assembly.
