ABSTRACT:
By providing a circular, dished agricultural disc with peripheral V-shaped notches and intervening ovate-shaped openings, 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 furrows inbetween.
