Abstract

The lawn cultivator possesses cultivating cutters (12, 14) which can be set in rotation by a cutter shaft (20), and whose cutting edge (34) forms an undercut and makes a transition, at an obtuse angle, into the leading edge (30). The radius line (40), guided through the cutting tip (38), runs along the cutting edge (34), or the cutting edge is set at a narrow advance angle, for example of 3 DEG , relative to this radius line. Since wear takes place on arcs (46) about the centre (24), a cutting tip with a cutting angle of approximately 90 DEG is always retained. Two cutting blades can be anchored to a double blade which is fixed on the shaft. This double blade can serve as a support for replacement blades which are to be attached diametrically, even after wear. It is also possible for a plurality of cutting teeth to be provided, in a staggered arrangement, whose cutting tips lie on radii which increase towards the rear in the direction of rotation, this guaranteeing that the tips are subjected to consecutive wear and a satisfactory cutting action is always available even after a prolonged period. <IMAGE>
