ABSTRACT:
A cultivator has groups of soil working members positioned in a row that extends transverse to the direction of travel. Each group includes a plurality of tined soil working members and a drive system that rotates each group as well as the individual soil working members of each group. The drive system is connectable to the p.t.o. of a tractor and comprises an elongated drive shaft that is geared to the central shaft of each group and a sun pinion of each central shaft is meshed with planet pinions on the shafts about which the soil working members rotate. The pinion gears of each group are housed in a circular disc-shaped casing so that the entire casing of each group rotates about its central shaft during operation. A forward coupling member is attached to the frame for connection to the tractor and a rear support roller provides support to regulate the working depths of the soil working members.
