ABSTRACT:
A pivot joint between a crop cutting sickle (13) and an offset drive arm (12) includes a pivot pin (37) which is connected to the sickle by antifriction bearings (23) and to the sickle drive arm (12) by a tapered wedging sleeve (43). Both ends of the pin (37) are threaded to receive nuts (57,58) which, when tightened, insure a tight joint which does not become loose when subjected to the reversing shock loads encountered in a crop cutting operation.
