A sickle header has a cutter bar having a mounting plate extending along the cutter bar, a top cutter bar assembly mounted to reciprocate in a side-to-side motion relative to the mounting plate, the top cutter bar assembly having an elongate top knife bar mounted on a top slide plate. The cutter bar has a bottom cutter bar assembly mounted to reciprocate in a side-to-side motion relative to the mounting plate, the bottom cutter bar assembly having an elongate bottom knife bar mounted on a bottom slide plate. The top and bottom knife bars have a row of knife sections and oppositely facing adjacent knife sections of the top and bottom knife bars effect a cutting action as the cutter bar assemblies are reciprocatingly moved sidewardly. The cutter bar has a sickle drive mechanism configured to drive the cutter bar assemblies in opposite sideways directions.

A side cutting unit for a cutting unit of an agricultural harvesting machine. The side cutting unit comprises a support frame designed as a bar rail, wherein the bar rail supports, in the longitudinal direction, at least one oscillating knife bar using blade holding apparatuses, and at one end is coupled to a drive that causes the oscillating movement of the at least one knife bar, with the bar rail being designed as a one-piece profiled tube, such as an extruded profiled tube.

A cutting system for a harvesting header includes a transversely extending cutter bar. First and second transversely extending knife backs are supported in relation to the cutter bar and are axially aligned with each other in a transverse direction. The first and second knife backs may each have a main body portion. At least one knife section is mounted to each of the first and second knife backs, each knife section having at least one knife edge extending generally in a forward direction. The first knife back is not attached to said second knife back. A crop divider structure is interconnected to the cutter bar and is operationally positioned between said first and second knife backs. The cutting system may also include first and second knife heads interconnected to the first and second knife backs and operable for interconnecting a knife drive system to drive the first and second knife backs.
