I claim:

A harrow of the class described comprising a beam, a Vertically disposed shaft carried thereby, a hub plate rotatably mounted upon the shaft, an annular 'member surrounding the hub plate and in spaced relation thereto, said annular member being substantially Z- shape in cross section, spokes radiating from the hub plate and operatively engaged with the base flange of the annular member, each of said spokes being substantially L-shape in cross section and provided with longitudinally spaced perforations in the base flange in close proximity to the upstanding flange, the base flange of the annular member being also provided with spaced perforations in Copies of this patent may be obtained for close proximity to the vertical portion thereof, a wheel operatively supported by one extremity of the beam and adapted to contact with the upper flange of the annular member, an arm operatively engaged with the beam, a wheel mounted upon said arm and adapted to travel upon the upper flange of the annular member, a weighted member adjustably supported upon the arm, and ground engaging members engaged with the annular member and the spokes and disposed through the openings therein.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

MARTIN J. RICHARD.
