PROBLEM TO BE SOLVED: To provide a levee plastering machine capable of forming always a fine new levee regardless of the state of a farm field.SOLUTION: A levee plastering machine 1 includes a pretreatment part 40 arranged on an off-set position to the side of a traveling machine body 90, for performing a land elevation work by cutting through a part of an old levee, and a levee shaping part 70 for shaping a new levee by plastering soil elevated by the pretreatment part 40 on the cut-through old levee. The pretreatment part 40 and the levee shaping part 70 are provided so that each relative position can be changed in the vertical direction. The levee plastering machine 1 is provided with a hydraulic cylinder 33 for changing a relative position in the vertical direction of the pretreatment part 40 and the levee shaping part 70, a soil amount detection sensor 35 capable of detecting the amount of soil heaped up by the pretreatment part 40, and a control part 50 for adjusting the relative position in the vertical direction of the pretreatment part 40 and the levee shaping part 70 by controlling operation of the hydraulic cylinder 33 in accordance with a detection value of the sensor so that the amount of soil supplied to the levee shaping part 70 becomes constant. |
