PROBLEM TO BE SOLVED: To provide a border coating machine that eliminates the risk that a tilling claw and a holder for holding it are worn away due to coming into contact with the soil deposited on an inner surface of a cover body for covering a pre-processing part.SOLUTION: A border coating machine includes a pre-processing part 61 for leveling an old ridge and heaping the soil, and a ridge arranging part for coating the heaped soil on the old ridge. The pre-processing part 61 has tilling claws 63, 64, 65 disposed in three lines in the shaft core direction at a tillage shaft 62 extending in the fore-and-aft direction to the traveling direction. These tilling claws have vertical blade parts 63b, 64b, 65b and horizontal blade parts 63c, 64c, 65c continuously extending from the mounting base, and reversely curved in the rotation direction of the tilling shaft 62 from the vertical blade part to the horizontal blade part, and further have the horizontal blade parts curved to one side with respect to the vertical blade parts. The horizontal blade part 65c of the third line tilling claw 65 is curved to the front side in the shaft core direction of the tilling shaft 62. The third line tilling claw 65 is provided with a soil removal member 75 covering the front side in the rotation direction of a holder 66 mounted therewith and extending from a mounting base 65a to the side of the vertical blade part 65b. |
