ABSTRACT:
A conditioning mechanism utilizing a pair of counterrotating conditioning rolls for use in a hay harvesting machine is disclosed wherein at least one of the conditioning rolls is mounted for transverse reciprocating movement relative to the other conditioning roll. An oscillating mechanism is provided to effect the transverse reciprocating movement of the at least one conditioning roll upon rotation thereof. Associating the oscillating mechanism with both the upper and lower conditioning rolls permits a shorter stroke of linear movement for each respective roll while permitting a general counterbalancing of the movements thereof. A positioning of the oscillating mechanism to provide for the relative movements of the conditioning rolls to be slightly out of phase will insure a continuous transverse movement of the conditioning roll to be applied to the crop material passing therebetween.
