Abstract

A work vehicle is formed from a plurality of ground-contacting motive elements, a chassis, an operator station, a switch, and a hydraulic manifold. The operator station has a joystick having a manually-actuable control element used to actuate the switch. The hydraulic manifold has a pair of primary hydraulic ports, first and second pairs of secondary hydraulic ports, and a control valve. The control valve is actuated by the switch and is adapted to allow pressurized hydraulic fluid to flow through a selected one of the first or second pair of secondary hydraulic ports. Each pair of secondary hydraulic ports fluidly communicates with a hydraulic actuator carried by a work attachment. By actuating the control element on the joystick, the operator can conveniently switch the hydraulic control of the joystick between different hydraulic operations on the attachment without leaving the operator's station.
