ABSTRACT:
A soil cultivating implement has an elongated frame portion and a plurality of rotatable members mounted at the lower ends of respective elongated shafts. Each member includes a carrier and tools on radial arms are connected to the carrier. The carrier is fastened to a nonrotatable tube through a hood and flange arrangement that prevents stalks and the like from fouling the shaft housed within the tube. The tools can be rigid tines or resilient strip-like blades which are angled downwardly in the direction of rotation. Guides in the form of rods can be mounted to coextend with the tools, upwardly to the rear so that soil loosened by the tools is displaced upwardly by forces that crumble the displaced soil before the latter falls rearwardly. Drive to shafts is effected through a gear box on the frame portion and further shafts that have pinions in mesh with those on the soil working member shafts. A further implement can be linked to the frame portion and driven via a rear shaft of the gear box.
