The invention relates to a so-called finger weeder, comprising a frame displaceable over a field and having suspended therefrom a number of weeding implements (14) which each consist of a rotatable body (14) which is provided with drive means (16) and a number of protruding weeding members (18), wherein the weeding members (18) are fastened to an auxiliary body (17) which is releasably connected to the rotatable body (14). The weeding members (18) can herein be embodied as fingers and formed integrally with the auxiliary body (17), for instance of a rubber or elastomer. The weeding members (18) can also be embodied as brushes. The invention also relates to a weeding implement for application in such a weeding device and to an auxiliary body (17) with weeding members (18). |

Bei einer Hack- und Jätmaschine, insbesondere in mehrreihiger Ausführung, bestehen die an Kreiseln 17 angeordneten Arbeitswerkzeuge 1,2 aus sich an an oberen Befestigungsabschnitten 2'',60 angebrachten vertikalen Schenkeln 1',2' an welche sich unten nach dem Kreiselinnern abgewinkelte Schenkel 1'',2'' anschließen. Eine leichtzügige einen geringeren Leistungsbedarf erfordernde und insbesondere einen Bodenantrieb bzw. größere Arbeitsbreiten ermöglichende Ausführung der Arbeitswerkzeuge 1,2 besteht darin, daß die unteren Schenkel 1'',2'' in einem spitzen Raumwinkel von den oberen abgewinkelt sind und somit tangential zu ihrer Umlaufbahn ausgerichtet einen ziehenden Schnitt ausführen. Zusätzlichen können zu diesem Zweck auch die oberen Schenkel 1',2' zur Umlaufebene der Kreisel 17 schräg angestellt sein. |

Discs (4 und 5) are mounted on a shaft (3) and cables (6) extend between the peripheries of adjacent discs (4 and 5) for use as ground engaging means. The shaft (3) and the discs (4 and 5) are rotated in the same direction as the wheels (2) of the cultivator, but a different peripheral speed. As a result of the difference in peripheral speeds of the wheels (2) and the discs (4 and 5), the cables (6) are caused to cultivate the ground. However, as the discs (4 and 5) are rotated in the same direction as the wheels (2), any weeds or other material dislodged by the movement of the cables (6) will be carried rearwardly by the cables (6) and deposited behind the cables (6), thus avoiding a build-up of unwanted material in front of the cultivator. |
