ABSTRACT:
An implement has rotatable cultivating members that are driven to rotate about upwardly extending axes. Each member includes a horizontal support arm and downwardly extending tools journalled at each end of the arm for free rotation. Along the length of each tool, are radial, superposed soil-working elements that are flat; the lowermost element can have cutting edges. The elements are separated from one another by spacer sleeves and are angularly offset relative to one another. Also, the elements can be different in configuration from one another and in one version, the tools are rotatable about axes that converge towards the axis of rotation of the corresponding member. When rotated and moved through the soil, the elements work ground at different levels to intermix the soil.
