PROBLEM TO BE SOLVED: To provide a levee plastering machine capable of scraping always a fixed amount of a top place of an old levee regardless of the state of a farm field.SOLUTION: A levee plastering machine 1 includes a top place treatment part 40 arranged on a sideward off-set position with respect to the traveling position of a traveling machine body, for cutting through the top place of an old levee to the moving end side of an off-set mechanism part provided rotatably rightward/leftward with respect to a traveling direction. The top place treatment part 40 is supported movably in the vertical direction by the off-set mechanism part. The levee plastering machine 1 is provided with a hydraulic cylinder 33 for moving the top place treatment part 40 in the vertical direction, a position detection sensor 80 for detecting a vertical position of the upper surface of the old levee with respect to the top place treatment part 40, and a control part for adjusting the vertical position of the top place treatment part 40 by controlling operation of the hydraulic cylinder 33 in accordance with a detection value of the position detection sensor 80 so that the depth of the top place of the old levee to be scraped by the top place treatment part 40 becomes constant. |
