ABSTRACT:
A cultivating implement has rows of tined soil working members that are freely rotatable about upwardly extending shafts. Each soil working member has tines positioned around the shaft which defines its axis of rotation. At the lower end of the shaft, a channelled feed member is attached and the shaft is hollow. Material from a container is dispensed from the container through the shaft and the feed member via a port to the ground being worked by the tines. The feed member is elongated and extends down, generally parallel to the tines of the corresponding soil working member which are mounted on circular plate supports. A further soil working member, preferably a supporting roller, is mounted behind the rows of soil working members.
