ABSTRACT:
An implement has rotatable soil working members that are driven to rotate about upwardly extending axes. The members each have a downwardly extending carrier that is releaseably connected to a driven shaft, and spaced apart soil working elements mounted along the length of the carrier. The elements are spaced apart by spacing pieces and the lower elements are fastened to their respective carriers by one or more bolts that pass through the lower pieces. At least one element, preferably the lowermost element, has obliquely extending portions that exert upward pressure on the soil being worked at different levels.
