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. |
