A steering system and method are described for a vehicle having steerable wheels. A steering device may be coupled to one or more of the wheels. A parked state of the vehicle and a present orientation of the hydraulic steering device may be determined. The present orientation of the steering device may be compared with a neutral orientation of the steering device. Based upon a determined parked state of the vehicle and the comparing of the present and neutral orientations of the steering device, the steering device may be moved from the present orientation toward the neutral orientation.

An articulated work vehicle with linked front and rear frames includes a joystick lever, a force imparting component, and a controller. The joystick lever can be moved to an inside or an outside with respect to an operator's seat by being operated by an operator, to change a steering angle of the front frame with respect to the rear frame. The force imparting component is configured to impart an assist force or a counterforce to an operation of the joystick lever by the operator. The controller controls the force imparting component so that an operating force required to move the joystick lever to the outside is different from an operating force required to move the joystick lever to the inside.

A self-setting valve assembly includes a plug, a first plunger assembly, a second plunger assembly, and a biasing member. The plug has a first portion and a second portion. The first plunger assembly is movably disposed within the first portion. The second plunger assembly is movably disposed within the second portion. The biasing member is disposed between the first plunger assembly and the second plunger assembly. The biasing member is configured to bias each of the first plunger assembly and the second plunger assembly towards a closed position.
