A drive arrangement for the reciprocating drive of a cutter bar comprises a hydraulic gear motor with a housing and a gearwheel, which is set in motion around a first axis by a hydraulic medium, and an eccentric drive, which comprises an eccentric element that can be rotatably driven by a gearwheel around a second axis parallel to the first axis, and a drive element connected to the eccentric element, which is, or can be, connected to the cutter bar.

Hydraulic drive arrangement to drive a reciprocating cutter bar

A drive arrangement for the reciprocating drive of a cutter bar comprises an input element which can be set into a continuous pivoting movement by a drive device, and an output element which is coupled to the cutter bar and is coupled to the input element by a coupling rod. The output element is pivotably connected to a first end of a first lever and of a second lever, which levers, for their part, are pivotably mounted. The levers and the output element are dimensioned in such a manner that the output element essentially only carries out a lateral movement.
