ABSTRACT:
A rotary harrow has a plurality of soil working members mounted in a row on a hollow frame portion that extends transverse to the direction of operative travel of the harrow. Each soil working member is rotatable about an upwardly extending axis through the intermediary of a first drive comprising a plurality of intermeshing pinions contained within the frame portion. A shaft defining the axis of rotation of a substantially central located soil working member is in connection with a second drive that connects to the power take off of a tractor. A third drive engages the first and second drives and is a speed reducing transmission that interconnects the first and second drives.
