Hydraulic steering () is disclosed comprising a high pressure port (P), a low pressure port (T), two working ports (CL, CR), a manual steering section (), and a steering valve section having a steering valveand a hydraulic driving arrangement () adjusting hydraulically a position of said steering valve. A change from automatic steering to manual steering should be reliably ensured when the manual steering section is directly influenced by a driver. To this end, a switching valve () is provided, which is actuatable between a first position in which said driving arrangement () is supplied with hydraulic fluid under pressure, and a second position in which a supply of hydraulic fluid to said driving arrangement () is interrupted, wherein said switching valve () is hydraulically actuated into said second position by a pressure generated upon actuating of said manual steering section ().
