A ground cultivating tool for being connected to a brush saw has the shape of a body (2) which is formed in one piece of sheet-metal, which body comprises on one hand a flat, circular basic part (9) with an aperture (13) for the connection to the brush saw, and on the other hand a cup-shaped part (10) protruding from the periphery of the basic part (9), in which cup-shaped part are provided three countersinks (11) which delimit a corresponding number of equidistantly separated working teeth (12, 12', 12''). The contour or delimiting edge of the individual countersink is on one hand arched as observed towards the envelope surface of the cup part, and on the other hand substantially rectilinear as observed in a planar projection perpendicularly to the plane of the basic part. |
