ABSTRACT:
A baler for forming large cylindrical bales of crop material has a baling chamber in which the crop is rolled into a bale by oppositely moving runs of side-by-side belts. A windrow of crop material is fed through an inlet of the baling chamber by a pick-up which lifts the windrow of crop and delivers the same to a feeder fork mechanism which in turn moves the crop into the inlet. Crop enters the baling chamber between a roll, over which the belts are trained, and a growing bale core. In order to reduce plugging of the crop at the inlet, the roll has discs rigidly mounted on it between neighboring belts. These discs each have an outer edge which is approximately sinusoidal in configuration and the peaks of the undulations extend outwardly beyond the thickness of the belts. The effect of the discs is both to grip the crop better and to raise the bale core slightly to provide easier access to the chamber for the crop.
