PROBLEM TO BE SOLVED: To provide a new tilling blade that reduces the number of times of tilling, improves work efficiency and reduces fuel cost, in which a conventional tilling blade is curved in the shape of a boomerang (sharp bend) so that a blade edge conforms to the surface of soil as shown in Fig. 7, and thereby the soil is scraped off so that blade edge brushes the surface of the soil when plowing the soil, and the blade is gradually entrenched in the soil to plow it, accordingly a plurality of times of tilling are necessary to deeply plow a hard field.SOLUTION: A tilling blade of a tiller is characterized in that: a plowing blade is formed by curving a flat steel in a substantially J-shape and sharpening the tip as a blade edge； a vertical blade curved in the substantially J-shape is attached to the plowing blade； and further an attaching part is provided in which the plowing blade is fixed in a drive shaft of the tiller.【課題】従来の耕耘刃は図７のように刃先が土の表面に沿うようにブーメラン状（くの字状）に曲がっているので、土壌を耕起する際、刃先が土壌の表面を撫でるように削り取り次第に土中に食い込んで耕起している。この為、硬い畑を深く耕起するには複数回の耕耘が必要である。 そこで、耕耘回数を低減させ作業効率の向上と燃料費の低減を図れる新規な耕耘刃を提供するものです。【解決手段】平鋼を略Ｊ字状に湾曲させ先端を刃先として尖らせて成る耕起刃に、略Ｊ字状に湾曲した縦刃を取付け、更に、前記耕起刃を耕耘機の駆動軸に固定さす取付部を設けたことを特徴とした耕耘機の耕耘刃である。【選択図】図２
