ABSTRACT:
A pair of cooperating elongated cutting members is mounted on the frame of a harvester for reciprocation along a common plane located intermediate the cutting members by means of arms pivotally connected to the frame and to the cutting members. A lever is pivoted to each of the cutting members and to the frame and has the same effective length as the associated arm, the pivot points of the associated arm and lever being located in the corners of an imaginary parallelogram. A crank drive moves a pair of connecting rods which are articulated to the respective levers intermediate the pivot points thereof. The cutting members have a plurality of recesses which are laterally bounded by cutting edges extending transversely of the elongation of the respective cutting members so that the objects which enter into the recesses are cut by the cutting edges in the common plane. The axis of rotation of the crank may be vertical, while the levers and arms may reciprocate in parallel horizontal planes. A hydraulic motor for driving the crank may be located directly above the crank, and the crank may be mounted on the output shaft of the motor for shared rotation therewith.
