PROBLEM TO BE SOLVED: To provide a flat high levee forming machine that can form a flat high levee without generating a large amount of surplus soil in a levee groove.SOLUTION: A flat high levee forming machine F is equipped with a pair of levee forming culture soil devices E at both ends in the width direction of the frame 21. The levee forming culture soil device E includes: a main side surface forming plate B; a soil guiding plate C which is arranged in the front end of the main side surface forming plate Bin a state facing obliquely forward in a plan view, which is integrally mounted on the frame 21, and which guides the soil softened expandingly by a rotary tillage device R to the side of a flat high levee K immediately before forming; and a sub side surface forming plate Bwhich is mounted on the tip end along the extending direction of the soil guiding plate C in a manner oppositely arranged on the outer side of the main side surface forming plate B, which is for forming a complete levee groove D by guiding expandingly softened soil left on the side surface of the flat high levee K formed immediately before, during the formation of the flat high levee, or which is for newly forming an incomplete levee groove D' in the expandingly softened soil by cooperating with the oppositely arranged main side surface forming plate B. |
