Abstract
A vehicle includes a coupling for mounting an implement and a load-controlled hydraulic pump that runs continuously with an engine of the vehicle. The pump draws hydraulic fluid from a low-pressure line region and feeds the hydraulic fluid into a high-pressure line region. The high-pressure line region has a high-pressure connection and the low-pressure line region has a low-pressure connection for supplying the mounted implement. A shutoff valve for blocking the flow of hydraulic fluid to the high-pressure connection is connected upstream of the high-pressure connection in the high-pressure line region.
