The present invention discloses a four-wheel drive travelling machine driven by four hydraulic motors. The four-wheel drive travelling machine is characterized in that oil circuits of hydraulic motors for driving a pair of wheels among front wheels or rear wheels are opened and closed by a hydraulic valve, and clutches are disposed between the hydraulic motors and the wheels driven thereby, and thus the four-wheel drive travelling machine is changed into two-wheel drive travelling machine through operation. The four-wheel drive travelling machine driven by the four hydraulic motors has advantages of four-wheel drive, and also the ferry speed of the travelling machine can be raised without raising the power supply ability of pumps.
