PROBLEM TO BE SOLVED: To provide a levee-forming machine designed to divide a disk which is a rotator, exchange parts and have good levee-forming performances in the levee-forming machine forming the levee with a banking apparatus for feeding soil to a levee-forming site into a banked state and forming the levee top surface part and the side part with the rotating rotator provided at the rear of the banking apparatus. SOLUTION: The disk which is the rotator of the levee-forming machine is integrally composed of a cylindrical disk forming the levee top surface, a conical disk forming the levee side and an intermediate disk located in the intermediate part of the cylindrical disk and the conical disk so as to be dividable. The surface of the conical disk is composed by overlapping the rear side of each radial divided piece directed toward the center of rotation with the front side in the rotative direction and detachably fixing each divided piece.
