Abstract: In a rotary crop baler for producing cylindrical crop bales, a simulated bale size and shape indicator is provided which provides the baler operator with a graphic representation of the size and shape of the bale being formed in the baler. The preferred indicator includes a potentiometer for producing a signal representative of the overall size of the bale, a plurality of potentiometers for producing corresponding signals representative of the shape of the bale, and an indicator including a signal processor and display liquid crystals or the like for producing the graphic simulation of the size and shape of the bale being formed.

Abstract: The baler has an internal chamber within which crop materials are coiled up into a cylindrical bale by fore-and-aft spaced-apart, oppositely moving web stretches, the forwardmost stretch of which is looped around a forward drive roll. A special bale supporting roller adjacent the bottom of the chamber keeps the bale from riding against the web wrapped around the forward roll. The support roll includes a cylindrical shaft and a plurality of resilient flaps extending tangetially outward from the periphery of the shaft. During baler operation, crop material tends to be carried downwardly by the forwardmost stretch into a zone located between the forward roll and the support roller, but is immediately ejected from the zone by the roller flaps and into the baling chamber, thereby preventing crop materials from wedging between the forward roll and the support roller.

Abstract: A round baler having a shiftable repositioning member for moving a completed, discharged bale of hay away from the baler is provided with an interlock mechanism for preventing movement of the repositioning member until such time that the bale has been discharged from the chamber. A sensor is located on a side of the baling chamber to determine the absence of a bale, and preferably takes the form of a rounded element biased toward a position normally protruding into the chamber. The presence of a bale within the chamber causes the element to shift outwardly and thereby close a valve interposed in a hydraulic circuit for providing motive fluid power to a piston and cylinder assembly that, in turn, drives the repositioning member.

Abstract: The baler has a set of belts which bear against the surface of a cylindrical bale during formation thereof to compact the bale and to drive it rotatably about its longitudinal axis. Such belts are guided by shafts spanning the chamber of the baler, certain of which may be provided with annular expelling collars that rotate with the shaft and function to reject and expel stray crop material from the immediate vicinity of the shaft in order to prevent its accumulation and buildup. In the particular embodiment illustrated, the collars are attached to opposite ends of a shaft carried by the belt tensioning assembly whose shafts bear directly upon the top periphery of the bale during its formation and thus have a greater tendency than others to accumulate materials straying from the baling chamber.

Abstract: Bales made from successive charges of material packed against one another are readily separable into relatively discrete "flakes" corresponding to the charges of material from which the bale is built. By passing the bale over the top edge of an incline just before reaching disintegrating mechanism, the leading end flakes of the bale are induced to successively separate therefrom for advancement on down the incline and delivery into the disintegrating mechanism on a more or less individual basis, thereby promoting clog-free operation and even feeding.
