PROBLEM TO BE SOLVED: To provide a leveling apparatus of a paddy field working machine, by solving such a problem that water-breaking disks thereof are apt to approach a surface of a levee, a barrier, etc., and to contact therewith, and therefore are easily deformed and broken, when operated in an area near the levee, etc., because the water-breaking disks are arranged in outside areas of side floats apart therefrom. SOLUTION: This leveling apparatus of the paddy field working machine is structured so that the water-breaking disks 3 which restrain flows of muddy water outward pushed by the side floats 2 and are freely rotatable are arranged in outside areas of the side floats 2 which are arranged on a bottom area of a working unit, slide on a soil surface, and level the surface. Thus, the water-breaking disks 3 are rotated by resistance caused by receiving of waves of the muddy water, and therefore the disks decrease adhesion of muddy soil thereto, decrease water-breaking resistance, and further decrease resistance against propulsion of the working unit.
