A large round baler is provided with a crop take-up arrangement as well as a knife shaft ahead of the inlet of a baling chamber which carries knives that cooperate with blades of a first rotor to cut crop material into pieces before the first rotor delivers the crop directly into the baling chamber. A second rotor is provided between the take-up rotor and the first rotor shaft for narrowing the crop flow from that of the crop take-up arrangement to that of the first rotor. All of the rotors perform an overshot conveying that requires a relatively low drive energy and guarantees a continuous flow of the crop into the chamber.

Crop recovery machine

A large round baler includes bale-forming means conducted over rotary bodies with stationary axes and rotary bodies with movable axes so as to define an expansible circumference of a baling chamber. Some of the movable rotary bodies are mounted to a carrier mounted to fixed side walls defining opposite sides of the baling chamber. The carrier is pivotally mounted to opposite side walls defining opposite sides of the baling chamber for movement between a lowered operating position and a raised discharge position wherein it holds a span of the bale-forming means, which during operation, forms the rear portion of the circumference of the baling-chamber above the formed bale so that the latter may be discharged.

Light discharge gate for large round baler

A large round baler is equipped with a chassis, including an outer pair of fixed side walls, that extend rearwardly beyond a pair of inner side walls which form opposite sides of a baling chamber. In an upper region of the baler, belts or the like are supported by a plurality of fixed rotary bodies extending either between the inner or the outer side walls and a movable rotary body carried at the end of a pivotally mounted tension arm, to form a large take-up loop that becomes smaller as a run of the belts expands during growth of the bale being formed. The run of belts, which is looped about the bale being formed, is conducted over rollers carried by a vertically pivoted frame, such that when the frame is swung between a lower extreme position, which it occupies during formation of a bale to a raised position, the formed bale is deposited on the ground.

Round baler having simplified bale discharge structure

A rotor includes a tube having an outer cross section which is non-circular onto which is assembled one-piece drivers provided with central openings of the same shape and size as the outer circumferential surface of the tube and thereby create a connection, fixed against rotation, between these parts. The rotor is shown used in a crop reducing arrangement of a large round baler.

Crop-feeding rotor having center shaft of non-round cross-section

A large round baler includes an expansible baling chamber having an inlet at a forward location thereof and defined in part by a lower run of a flexible, endless component arrangement of an upper conveyor, and by an upper run of a flexible, endless component arrangement of a bottom conveyor. In each of two embodiments, the bottom conveyor includes a moveable roller which operates to selectively deflect the upper run of the bottom conveyor so that it cooperates with a lower run of the upper conveyor so as to define a baling chamber having a cross section conducive to starting a bale core at the beginning of the baling process and moveable to a discharge position for allowing a completed bale to roll onto the ground. In the second embodiment, the upper conveyor also includes a moveable roller that operates to yieldably resist expansion of the lower run of the upper conveyor.

Large round baler with baling chamber including one or more conveyor rolls movable between bale-forming and discharge positions

A baling chamber for a large round baler includes a discharge gate having opposite side walls which meet respective side walls of the main frame along a line of separation that inclines downwardly and to the rear from top to bottom. The bottom of the baling chamber is defined in part by a bottom conveyor which slopes downward to the rear from a front end which delimits a lower side of an inlet through which crop is fed into the baling chamber. The discharge gate carries a lower front roll that supports an endless tension element arrangement and that is itself supported on a tensioning arm arrangement that pivoted to the discharge gate for movement against the resistance of a yieldable spring arrangement so as to permit the lower front roll to move rearwardly from a first position adjacent the inlet, which it occupies at the beginning of bale formation, as the bale grows.

Baling chamber arrangement of a large round baler designed for quick bale discharge

The expansible baling chamber of a large round baler is constructed so as to have chamber-forming elements that act to bias a forming bale away from the chamber inlet so that harvest entering the inlet will be more easily wrapped onto the bale, these chamber-forming elements, in some embodiments, also acting to increase the tension of tensioning mechanism forming part of the baling chamber. Also aiding in the delivery of harvest to the baling chamber is a conveyor having portions located within the chamber inlet.

Large round baler having baling chamber constructed so as to facilitate the flow of harvest into the chamber

A large round baler includes a pick-up which delivers crop to a transport assembly including a guide wall and tined rotor, together with a rotor stripper, which cooperate to move harvest material from the pick-up to the inlet of a baling chamber. Various embodiments are disclosed for moving one or more of the guide wall, rotor or stripper for effecting adjustments narrowing or expanding the cross section of a guide channel for the harvest material defined in part by the guide wall, rotor and stripper. These adjustments can be done manually or with power and can be made in response to computer generated information or command signals resulting from collected and/or stored data indicating various conditions of the harvested material.

Adjustable harvest material transport assembly for moving the material from a pick-up to a processor inlet

A large round baler is equipped with a device for wrapping a bale formed in the baling chamber of the baler with a web of plastic sheeting or net wrapping medium. A supply roll of the wrapping medium is located in a box mounted forward of the baling chamber for movement along a fore-and-aft extending guide rail between a standby position, wherein a free end of the wrapping medium is supported by a guide surface at a location spaced forward of the baling chamber, and a wrapping position, wherein the free end of the wrapping medium is located for being grabbed by rotating rollers and/or the formed bale so that a length of the wrapping medium is pulled from the supply roll as it is wrapped about the bale. A power operated brake operates on the supply roll so as to provide a constant tension in the wrapping medium during wrapping operation.
