Abstract: A vehicle includes a frame, a hitch coupled to the frame, a cylinder positioned to move the hitch relative to the frame, the cylinder having a first chamber and a second chamber, and a fluid system fluidly coupled to the cylinder. The fluid system includes an action select valve reconfigurable between a single-acting configuration and a double-acting configuration. The fluid system is configured to supply a fluid to the first chamber to raise the hitch. When the action select valve is in the double-acting configuration, the fluid system controls the cylinder to lower the hitch by draining the fluid from the first chamber and supplying the fluid to the second chamber. When the action select valve is in the single-acting configuration, the fluid system controls the cylinder to lower the hitch by draining the fluid from the first chamber without supplying the fluid to the second chamber.

Abstract: A locking assembly for a door assembly of an agricultural vehicle includes: an actuator that defines an actuator axis and is linearly movable between a first position and a second position and rotatable about the actuator axis between a first locking orientation and a second locking orientation and includes a pair of locking features; a biaser configured to bias the actuator toward the first position; an energizer configured to bias the actuator toward the first locking orientation when the actuator is in the second locking orientation; and a lock configured to engage a second locking feature when the actuator is in the second locking orientation. Linear movement of the actuator from the first position to the second position while the actuator is in the second locking orientation causes the lock to disengage from the second locking feature so the energizer rotates the actuator towards the first locking orientation.

Abstract: A quick response steering system with a steering device that steers a vehicle. An electro-hydraulic steering circuit couples to the steering device. The electro-hydraulic steering circuit includes a load sensing pump that pumps hydraulic fluid to a steering cylinder. The load sensing pump increases or decreases output from the load sensing pump in response to a pressure differential between a first fluid line and a second fluid line. A precharge valve diverts hydraulic fluid from the first fluid line to the second fluid line. A controller couples to the steering device and the precharge valve. The controller opens the precharge valve in response to input from the steering device to change a first pressure of the first fluid line to increase an output of the load sensing pump.

Abstract: An electro-hydraulic brake system includes a first brake input that generates a first brake input signal and a second brake input that generates a second brake input signal. The system also includes a first valve that releases hydraulic fluid to control a first brake and a second valve that releases the hydraulic fluid to control a second brake. The system includes a speed sensor that generates a speed signal indicative of a speed of a work vehicle. A controller receives the speed signal, the first brake input signal, and the second brake input signal, determines the speed of the work vehicle based on the speed signal, and compares the speed of the work vehicle to a threshold speed. The controller synchronizes actuation of the first and second valves in response to the speed being in excess of the threshold speed to control the first and second valves.

Abstract: The present inventors have recognized that contaminants in hydraulic fluid in a hydraulic system of an off-highway implement can be efficiently filtered by a filtration system of the source of hydraulic power by conducting an operation which controls existing valves for precisely operating cylinders of the system to return the fluid to the source of hydraulic power through a connector with little or no fluid going through cylinders. Such an operation can be advantageously executed immediately following connection of the source of hydraulic power to the manifold of the implement.
