ABSTRACT:
A knife assembly for mounting in a combine header for cooperation with the radial feed fingers of the central drum portion of a rotary auger in which a plurality of transversely spaced knife bars fixed to a knife frame are pivotally supported upon a mounting frame fixed in relation to the feed opening of the combine header, so that the cutting edges of the knife bars are closely spaced to the central drum portion of the auger and interdigitate with the radial feed fingers of the auger drum portion, in order to cut exceptionally long vegetation, such as stalks or vines, carried by the auger before such vegetation reaches the feed opening to the combine.
The knife assembly further includes adjustable stop means for accurately locating the cutting edges of the knife bars close to the central drum portion of the auger, and a locking means for locking the knife bars in an elevated inoperative position to permit cleaning out the cut vegetation in the central drum portion of the auger.
