PROBLEM TO BE SOLVED: To provide a ridge coating machine capable of eliminating a risk in which the tilling claws and a holder for holding this are worn out by coming in contact with soil adhering to an inner face of a cover body covering a pre-processing unit.SOLUTION: A ridge coating machine includes a pre-processing unit 61 for leveling an old ridge and performing soil heaping and a ridge-forming unit for applying the heaped soil on the old ridge. The pre-processing unit 61 has the tilling claws 63, 64, 65 arranged in 3-rows in the shaft core direction at a tilling shaft 62 extending in the longitudinal direction to a traveling direction. These tilling claws have vertical blades 63b, 64b, 65b and horizontal blades 63c, 64c, 65c continuously extending from a mounting base and are curved in the reverse direction of rotation of the tilling shaft 62 over the horizontal blades from the vertical blades, and also the horizontal blade is curved to one side to the vertical blade. The horizontal blade 65c of the 3-row tilling claw 65 is bent toward the shaft core direction front side of the tilling shaft 62. In the 3-row tilling claw 65, a soil removal member 75 is provided that covers the rotating direction front side of a holder 66 mounted of this and extends from a mounting base 65a to the vertical blade 65b side.SELECTED DRAWING: Figure 4【課題】前処理部を覆うカバー体の内面に付着する土と接触して耕耘爪やこれを保持するホルダが摩耗する虞のない畦塗り機を提供する。【解決手段】畦塗り機は、旧畦を切り崩して土盛りを行う前処理部61及び盛られた土を旧畦上に塗り付ける整畦部を備える。前処理部61は、進行方向に対して前後方向に延びる耕耘軸62に軸芯方向3列に配設された耕耘爪63,64,65を有する。これらの耕耘爪は、取付基部から連続して延びる縦刃部63b,64b,65b及び横刃部63c,64c,65cを有し、この縦刃部から横刃部にかけて耕耘軸62の回転方向逆向きに弯曲し、横刃部が縦刃部に対して一側方へ弯曲する。3列目の耕耘爪65の横刃部65cは、耕耘軸62の軸芯方向前側へ向いて屈曲する。3列目の耕耘爪65には、これが装着されるホルダ66の回転方向前側を覆い、且つ取付基部65aから縦刃部65b側へ延びる土除去部材75が設けられる。【選択図】図4
