To provide a tilling claw that is capable of extend life by making uneven wear be hard to be caused, and capable of preventing tilling performance degradation.SOLUTION: A tilling claw concerning the present disclosure has a mounting base mounted in a tilling shaft, a vertical blade part extending continuously from the mounting base, and a horizontal blade part continuously extending from the vertical blade part. The tilling claw is curved in the direction reverse to the rotating direction of the tilling shaft over a horizontal blade part from the vertical blade part, and has the horizontal blade part curved in one side of the rotating shaft direction of the tilling shaft to the vertical blade part. In the cutting edge side of the vertical blade part and the horizontal blade part, a hard metal part with hardness higher than the other portion is provided over the horizontal blade part from the vertical blade part. The end of the mounting base side of the hard metal part is positioned in the substantially same position as a bladed end of the vertical blade part. The end of the tip side of the hard metal part is positioned in the end vicinity of the horizontal blade part.SELECTED DRAWING: Figure 6【課題】偏摩耗を生じにくくすることで、長寿命化を図ると共に耕耘性能の低下を防止することのできる耕耘爪を提供する。【解決手段】本開示にかかる耕耘爪は、耕耘軸に取り付けられる取付基部と、前記取付基部から連続して延びる縦刃部と、前記縦刃部から連続して延びる横刃部と、を有し、前記縦刃部から前記横刃部に渡って前記耕耘軸の回転方向と逆方向に湾曲させ、前記縦刃部に対して前記横刃部が前記耕耘軸の回転軸方向の一方に湾曲させた耕耘爪であって、前記縦刃部及び横刃部の刃縁側には、前記縦刃部から前記横刃部に渡って他の部分よりも硬度が高い硬質合金部が設けられ、前記硬質合金部の前記取付基部側の端部は、前記縦刃部の刃付け端部と略同じ位置に位置しており、前記硬質合金部の切っ先側の端部は、前記横刃部の端部近傍に位置している。【選択図】図６
