Abstract

The rotary harrow has rotary tools whose teeth comprise thin downwardly directed blades each with an upper horizontal portion which is fixed to a tool carrier. Ther front edges of the teeth, in the direction of rotation, are inclined so that the upper end is in advance of the lower end. The horizontal portion has an oblique cut away at its leading edge so that the outer end is always behind the inner end in the direction of rotation. The teeth are parallel or converge towards the bottom.
