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.
