Abstract (en)
[origin: WO2010028953A1] The invention relates to an attachment cutting system having an attachment bracket (02) for attaching to a moving carrier arm of a carrier device. The attachment cutting system comprises at least one motor (11) and two cutting heads (03) which are rotationally driven by said motor, are attached at both sides of the longitudinal axis of the attachment bracket (02), and carry numerous cutting teeth (04). Furthermore, a rotating cutter chain (01) having numerous cutting teeth (04) is provided, the direction of travel of which runs parallel to the longitudinal axis of the attachment bracket (02) and which extends between the two cutting heads (03), wherein the front reversing line of the cutter chain (01) lies substantially in a plane tangent to the outside cutting surfaces of the two cutting heads (03), and wherein the motor (11) driving the cutting heads (03) also drives the cutter chain (01).
