PROBLEM TO BE SOLVED: To drive a hydraulic actuator of a working machine system by a simple driving circuit without having an adverse affect on the other hydraulic actuator. SOLUTION: In this working vehicle (combine 1) provided with HSTs 19, 20 for changing gear for the power of a traveling system, a working machine driving circuit (discharge switching valves 46, 47) are connected with charge circuits of the HSTs 19, 20, and the hydraulic actuator (discharge motor 14) of the working machine system used in stopping the traveling, is driven by oil pressure taken out from the charge circuits.
