ABSTRACT:
A cutter mechanism (1) for a combine-harvester comprises a frame (2) forming a trough (6) from a rear wall (3), two side walls (4) and a floor (5) used as a cutting table, which frame (2) receives an adjustably inserted cutter bar (7) on the input side of the trough, connecting points for holding outer dividers (9), side cutters (10) or the like in the end regions of the cutter bar or side walls (4), a reel (12) of the reaper which is displaceable via actuating drives (11) above the cutter bar (7), and a feed screw (15) which is situated within the trough (6), with the floor (5) being transversally divided and being composed of a rear floor part (16) fixed to the frame for the purpose of adjusting the cutting table length to the respective reaping conditions and of a front floor part (17) which is guided in a slide-adjustable manner relative to the frame in the direction of the travel, and with both floor parts overlapping each other along the path of displacement.In order to achieve a simple and reliable construction, the front floor part (17) is insertable underneath the rear floor part (16) when shortening the cutting table and a stripper (21) which projects from the front edge (20) of the rear floor part (16) is provided as a transition between the two floor parts (16, 17).
