Abstract

A windrow merger having a plurality of rotationally driven tines that rotate around a non-circular cam to vary the rotational speed of the times. The tines extend from the cam on elongated cam followers such that the tines are moved through a flicking motion as the tines are rotated around the cam. The window merger also has an internal drive assembly positioned in an internal aperture around which the rotatable tines are rotated.
