ABSTRACT:
A cultivating implement or rotary harrow has two groups of soil working members mounted on upwardly extending shafts that extend transverse to the direction of operative travel. The groups of soil working members are adjustably linked to an elongated frame of the harrow and the front of the longer side of the frame has a coupling member for connection to the rear of a prime mover for soil working operation. One of the shorter sides has a second coupling member that can be coupled to the prime mover during transport. Pairs of ground wheels at the front and rear of the frame are employed to support the harrow both in operative and in transport positions. Each group of soil working members has a supporting rear roller and arms that extend from the front of the frame over the roller to support a tool bar to which seed drills, for instance, can be connected.
