PROBLEM TO BE SOLVED: To provide a plowing claw capable of improving clod breaking and inversion performance.SOLUTION: A plowing claw 35 comprises a mounting base 41, a vertical blade part 42, and a horizontal blade part 43. The vertical and horizontal blade parts 42 and 43 have a blade edge part 46 and a peak edge part 47. A tangent line B in a horizontal peak edge tip position b is inclined to a base end side at a tilt angle α larger than 0 degree and smaller than or equal to 15 degrees with respect to a vertical line C in a side view in a state in which the plowing claw is mounted so that a vertical blade edge tip position a can be a lowermost position.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】砕土・反転性能の向上を図ることができる耕耘爪を提供する。【解決手段】耕耘爪35は、取付基部41、縦刃部42および横刃部43を備える。縦刃部42および横刃部43は、刃縁部分46および峰縁部分47を有する。縦刃縁先端位置aが最下位置となるように取り付けた状態の側面視で、横峰縁先端位置bにおける接線Bは、鉛直線Cに対して0度よりも大きく15度以下の傾斜角度αをもって基端側へ傾斜している。【選択図】図2
