Hydraulic drive in which a hydraulic motor around the driving wheels is connected in parallel to one hydraulic pump, and a hydraulic motor for the other auxiliary driving wheel and a hydraulic motor for the other main driving wheel are connected in parallel to the other hydraulic pump. In the device, a pair of oil passages for connecting the two hydraulic pumps in parallel, a first switching valve that simultaneously connects and disconnects both oil passages, an outlet of the main drive wheel hydraulic motor on one side and an outlet on the other side. An oil passage connecting the inlet 2 and the opening of the hydraulic motor for the main drive wheels, a second switching valve that connects and disconnects this oil passage, and an outlet of the hydraulic motor for the main drive wheels on one side to the other hydraulic pump. A third oil passage that simultaneously connects and disconnects the oil passage that communicates with the oil passage that communicates the inlet of the other main drive wheel hydraulic motor with the other hydraulic pump.
A fourth switching valve that connects and disconnects the oil passages connecting each hydraulic motor for each auxiliary drive wheel to each corresponding hydraulic pump.
A hydraulic drive device for a vehicle, characterized in that it is equipped with a switching valve.
