ABSTRACT:
A cultivating implement has a row of rotors that are driven to rotate about upwardly extending axes and an elongated roller with pins that project obliquely rearwardly, considering the normal direction of rotation of the roller. The roller is mounted on arms that are pivoted to the frame on pivots. On the rear ends of the arms, a carrier is pivoted and elongated scraper elements are mounted along the length of the carrier. The elements can be mounted in groups or single and extend forwardly and downwardly so that their forward end parts bear on the roller's surface between the pins. Gaps in the elements or between same allow the pins to pass during rotation of the roller. The carrier is interconnected with the arms by springs that bias the end parts into contact with the roller's surface.
