The vehicle has load-controlled hydraulic pump (1) that runs continuously with engine of vehicle for drawing hydraulic fluid from low-pressure line region (9) and for feeding hydraulic fluid into high-pressure line region (3). The high and low-pressure line region is provided with respective high and low-pressure connection (11,13) for supplying mounted implement that is coupled to vehicle. A shutoff valve (23) blocks the flow of hydraulic fluid to high-pressure connection that is connected to upstream of high-pressure connection in high-pressure line region.
