PCT No. PCT/AU95/00777 Sec. 371 Date Jun. 10, 1997 Sec. 102(e) Date Jun. 10, 1997 PCT Filed Nov. 24, 1995 PCT Pub. No. WO96/15655 PCT Pub. Date May 30, 1996A cultivator for the selective cultivation of limited ground areas, which includes a body adapted to be mounted on a prime mover, so that the body is able to be selectively brought into contact with the ground surface to be cultivated. A rotatable shaft extends outwardly from the body, with the work head being mounted on the rotatable shaft for permitting rotation thereof, and the shaft being driven by a motor. A pair of tines is connected to the work head and extends downwardly from the work head, with the pair of tines being diametrically spaced relative to the rotatable shaft and extending downwardly and inwardly, and being offset from each other so that, upon downward movement into the ground surface, the pair of tines form a conical area of disturbed soil, with the wall of the conical area of disturbed soil being worked differently by each tine of the pair of tines, so that as each tines passes over a part of a side of the cultivated area of the ground surface, the contact with the cultivated area by each tine will differ from the contact of the other tine of the pair of tines, with a substantially conical cultivated volume, having walls which are unglazed, being formed.
