ABSTRACT:
A soil cultivator has a beamed frame with a coupling member to be attached to a tractor. A plurality of rotatable tined soil working members are mounted in a row that extends transverse to the direction of travel. The soil working members are power driven by driving means to rotate about upwardly extending axes and work overlapping strips of ground. The action of the tines breaks up soil, even heavy soil, and a roller is connected to trail the soil working members. The roller has annular plates the outer peripheries of which are formed by horizontally extending elongated elements that engage and smooth the ground behind the tines. The roller is adjustably pivoted to the frame by arms to support the weight of the cultivator. By moving the arms about pivots, the working depths of the tines and the amount of weight borne by the roller can each be regulated to a significant extent.
