PROBLEM TO BE SOLVED: To provide a paddy field working vehicle enabling the stop of a machine body without fail even in the case of disconnecting the steering clutch of the inner side of turning direction and turning in a small radius by acting the right and left brakes by the operation of the clutch and a brake operation device, applying the braking force simultaneously to the right and left driving rear wheels and transmitting the braking force to the front wheels to apply the braking force to all four wheels. SOLUTION: The rear wheel driving system 40 has steering clutches 75L, 75R. Steering brakes 90L, 90R are placed at the downstream side of the transmission direction. Braking force is applied to the driving rear wheels independent of the connection and disconnection of the steering clutches 75L, 75R, the braking force of the side of the coupled steering clutch 75L (or 75R) is transmitted to a branch shaft 33 through a rear wheel shaft 61 and a propeller shaft 57, and the braking force is applied to the front wheel driving system 39 through the branch shaft 33 to apply the braking force to all four wheels including front wheels.
