ABSTRACT:
A cultivator implement has a row of soil working members mounted on upwardly extending shafts. The shafts extend to meshed pinion gears housed within an elongated hollow frame portion. Below each pinion two spaced apart bearings support the shaft and the bearings are mounted in a housing that is bolted to the upper surface of the lower part of the frame portion. The lower part can be profiled to receive the housings which include an enlarged circular or rectangular flange which is bolted to the profiled lower part. Each working member has a carrier mounted on a lower shaft portion and a group of tines is journalled for free rotation about an axis located at each opposite end of the carrier. The tines are secured in holders on arms and are angled to trail with respect to their normal directions of rotation. The working members each have two groups of tines that can be mounted to rotate in relative opposite directions and the tines normally move rearwardly between the axis of rotation of the corresponding member and the axis of rotation of the group as a whole.
