System for automatically controlling the bale shape in round balers

Abstract From the Canadian patent

A bale shape controlling system for round balers is disclosed. The system includes first and second indicator lights, and bale shape monitor apparatus for alternately generating signals in the indicator lights in response to predetermined expansion of the bale forming chamber of round balers. Typically round balers are operated in a manner whereby crop material is fed into only one side of the bale forming chamber at a time. The system also includes apparatus for automatically positioning round balers so that crop material is alternately fed into the right or left side of the bale forming chamber when signals are alternately generated in the indicator lights.
