PROBLEM TO BE SOLVED: To simplify the structure of a levee plastering machine and to prevent driving force transmitted from a traveling machine body to an operating part from reducing. SOLUTION: The levee plastering machine 1 is equipped with the operating part 20 provided at the rear end of an offset frame 5 mounted on the rear of the traveling machine body. The operating part 20 is equipped with a crown treating part 21 for breaking the upper part of an old levee U0, a pretreating part 31 for carrying out mounding of broken soil and a levee reshaping part 41 for plastering the mounded soil over the old levee. Each part is integrally mounted through a corresponding crown power transmission case 90, a corresponding pretreating power transmission case 50 and a corresponding levee reshaping power transmission case 60 on a rotation shaft case 11 covering a rotation shaft 10 receiving the driving force from the traveling machine body and carrying out rotation and driving. The interior of each transmission case has a crown power transmission mechanism 95, a pretreating power transmission mechanism 53 and a levee reshaping power transmission mechanism 63 transmitting the driving force from the rotation shaft 10 and built therein. The rotation central shaft 32 of the pretreating part 31 extends in the direction intersecting the rotation central shaft 42 of the levee reshaping part 41 and non-orthogonally interseting the rotation central shaft 42 when viewed in a plane.
