ABSTRACT:
A soil compacting roller comprises a cylinder rotatably mounted between the lower ends of substantially vertical limbs of two side supports. The cylinder is surrounded by a plurality of larger diameter rings which extend in relatively spaced apart, side-by-side relationship along the length of the cylinder. The roller also includes an internal tubular or rod supporting member spaced above the cylinder so that the rings are rotatable about that member and the cylinder entirely independently of one another. Guide members extend between the successively neighboring rings to keep them in position axially of the cylinder and to assist in dislodging adhering mud from the interiors and exteriors of the rings. The guide members can be in the form of pivotally mounted strips, spring steel rods, annular flanges carried at regular intervals along the cylinder, pairs of lugs carried by the supporting member or rotatably mounted circumferentially toothed discs which extend between the successive rings. In one embodiment, each ring is of annular, rather than cylindrical, formation. Also, the roller can be used in combination with a rotary harrow or a rotary cultivator having a plurality of soil working members that are rotatable about substantially horizontal axis.
