。Pressure oil from one pump is supplied in parallel to the left-hand drive motor and other actuators that drive the left-hand truck back and forth through operation valves, and pressure oil discharged from the other pumps is supplied through operation valves to the left-hand drive motor and other actuators that drive the left-hand truck back and forth. In a hydraulic traveling system for a tracked vehicle, which is connected in parallel with the right traveling motor and other actuators that drive the traveling truck back and forth, the forward passage between the left and right traveling motors and the reverse passage are provided. A communication valve is interposed between each passage, which opens when the hydraulic pressure in one passage is equal to or higher than a predetermined pressure equal to or higher than the return oil pressure, and allows the pressure oil in the other passage to flow into the passage. Hydraulic running system for tracked vehicles.
