ABSTRACT:
By providing a circular, dished agricultural disc with peripheral W-shaped notches, a small tooth being formed at the center of each notch, the disc may be operated at relatively high speeds while still achieving vigorous cutting, stirring and mixing of the soil. At the same time, excessive throwing of soil is avoided, thereby preventing soil accumulation into high ridges with wide intervening furrows.
