Abstract
A method is disclosed for unplugging or freeing a cylindrical baler which has a slug of crop material caught in the crop inlet of the bale forming chamber. A cylindrical baler used in the practice of this method is comprised of a plurality of belts supported on a plurality of rolls and defining a bale forming chamber. A pair of rolls on a carrier respectively engage a pair of stretches of the belts and substantially close an upper portion of the chamber. The rolls and carrier are upwardly moveable as the chamber expands responsive to the bale growth. The method comprises steps of (1) disengaging a drive means for the belts; (2) moving the carrier and rolls supported thereon upwardly away from the bale being formed in the chamber thereby enlarging the chamber; (3) automatically tensioning the belts responsive to carrier movement to cause the stretches to rotatably engage the bale and (4) re-engaging the drive means for feeding the slug into the chamber and wrapping the slug around the bale. In accordance with this method, the size of the bale forming chamber and the tension on the belts may be controlled, thereby permitting the bale forming chamber to accommodate large slugs of hay in the unplugging mode of operation and eliminating the need to manually remove the slug as has been typically required with prior art balers.
