Abstract
A harvester may include a chassis, a first separation frame movably supported by the chassis and upon which crop material is deposited, a second separation frame movably supported by the chassis and upon which the crop material is deposited; a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame and an adjustable link operably coupled between the separation frame and the chassis. The adjustable link facilitates adjustment of an orientation of the first separation frame independent of an orientation of the second separation frame without altering a reciprocation stroke distance.
