To provide a tilling claw that reduces vibration and a horsepower load in the tilling, and is superior in abrasion resistance.SOLUTION: A tilling claw is integrally constituted of a mounting base 1 attached on a mounting flange S0, a vertical blade part 2 composed of a flat plate to a horizontal blade curvature starting part F continuously extending from a mounting base 1, and a horizontal blade part 3 continuously extending from the vertical blade part 2 using the horizontal blade curvature starting part F as a boundary and having a horizontal blade curved part 30. A cutting edge part 4 is a double-edged blade whose both sides across the cutting edge are inclined to a thickness direction of the vertical blade part 2 and the horizontal blade part 3, a step difference part 6 extending along the cutting edge part 4 is formed in a curved outer surface of the horizontal blade part 3, and the horizontal blade part 3 is configured such that an area on a back 5 side is thinner than an area on the cutting edge part 4 side by the step difference part 6 as a boundary. The problem is solved by the tilling claw.SELECTED DRAWING: Figure 1【課題】耕耘時の振動や馬力負荷を低減し、耐摩耗性に優れる耕耘爪を提供する。【解決手段】取付けフランジS0上に装着される取付け基部1と、取付け基部1から連なって延びる横刃部湾曲開始部Fまでの平面板からなる縦刃部2と、縦刃部2から横刃部湾曲開始部Fを境として連なって延び横刃部湾曲部30を有してなる横刃部3とが一体的に構成されてなる耕耘爪であって、刃縁部4が、刃先を挟む両側面が縦刃部2及び横刃部3の厚み方向に対して傾斜している両刃であり、横刃部3の湾曲外側面には、刃縁部4に沿って延びる段差部6が形成されており、横刃部3は、段差部6を境として、背部5側の領域が刃縁部4側の領域より薄くなっている耕耘爪により解決することができた。【選択図】 図1
