In one embodiment, an agricultural crop baler comprising: a supporting frame; a pressing chamber configured to receive a stuffer, the stuffer compressing the crop into the pressing chamber; and at least one positionally adjustable side wall forming part of the pressing chamber, the side wall being supported by the supporting frame and configured to vibrate upon movement of the stuffer.

A baler includes a frame and a bale chamber structure that is supported by the frame. The bale chamber structure includes a plurality of walls that cooperate to define a baling chamber that extends along a longitudinal axis. The plurality of walls shape different sides of the bale. At least one of the plurality of walls includes a first segment panel that is moveably attached to the frame and a second segment panel that is arranged in a downstream direction from the first segment panel with respect to the longitudinal axis. The second segment panel is moveably attached to the frame independent of the first segment panel.

A baler including a frame having a first end, and a second end opposite the first end. The baler also having a compression chamber, where the compression chamber defines a central axis extending longitudinally therethrough, a plunger assembly at least partially positioned and movable within the compression chamber, and a panel removably coupled to the frame, and where the panel at least partially defines the compression chamber.

A crop baler with a stuffer flywheel mass for baling a crop, the baler comprising: a supporting frame that can be moved across a field; a crop pick-up configured to pick up the crop from a ground of the field; a conveyor configured to convey the crop picked up by the crop pick-up; a pressing chamber having a stuffer configured to compress the crop conveyed into the pressing chamber by the conveyor into a form of a bale; and a drive for producing a reciprocating movement of the stuffer, the drive further comprising a flywheel mass with a variable moment of inertia.

A baling system operable to receive loose material, form the loose material into an individual charge, and compress the individual charge with one or more other charges to form a bale. The baling system includes a forming chamber and a plunger operable to move in a reciprocating manner within the forming chamber from a front-dead-center position in which a plunger face is furthest re) from the bale to a rear-dead-center position in which the plunger face contacts and compresses the bale. The system includes a feeder el component operable to pre-compress the loose material to form the individual charge and then move the individual charge into the forming chamber, the feeder component including a feeder chute having a feeder chute outlet connected to the forming chamber. The feeder component is operable to pre-compress the loose material into the individual charge and then move the individual charge into the forming chamber for compression by the plunger into the bale. The system includes a moisture sensor operable to determine a moisture content of the individual charge in the feeder chute, wherein at least a portion of the moisture sensor is positioned in the plunger face. In one embodiment, the moisture sensor is a near infra-red sensor operable to use near infra-red radiation to determine the moisture content.

A crop baler comprises a frame, a pressing chamber for crop, into which a stuffer can be introduced in order to compress the crop into a bale, a drive for producing a reciprocating movement of the stuffer, and a countermass coupled to the drive and configured to move in a counteracting direction to the movement of the stuffer, the countermass at least approximately compensates movement of the frame induced by the reciprocating mass of the stuffer and the drive unit thereof due to inertia. Alternatively or additionally, a flywheel mass of the drive can have a variable moment of inertia to similarly compensate movement of the frame induced by the reciprocating mass of the stuffer.

A square baler comprising a gear box configured to receive power from a rotating power source. The baler additionally comprises first and second drive shaft sections extending outwardly from generally opposite sides of the gear box. The gear box is configured to rotate said first and second drive shaft sections using power from the rotating power source. The baler further comprises first and second reciprocating plungers respectively coupled to the first and second drive shaft sections in a manner such that rotation of the first drive shaft section causes reciprocation of the first plunger and rotation of the second drive shaft section causes reciprocation of the second plunger.

A high capacity square baler comprising a pickup mechanism configured to pick up a single windrow of crop material off the ground. The baler additionally comprises one or more stuffer chutes each configured to receive at least a portion of the crop material picked up by the pickup mechanism. The baler additionally comprises one or more stuffer assemblies each configured to push crop generally upward through one of the stuffer chutes. The baler further comprises a plurality of separate bale-forming chambers each configured to receive crop material from one or more of the stuffer chutes and to form a bale of crop material therein.

A square baler comprising a first bale-forming area in which are formed a first series of first individual bales, and a second bale-forming area in which are formed a second series of second individual bales. The square baler additionally comprises a singulator configured to receive the first and second individual bales from the first and second bale-forming areas and to form a single row of the first and second individual bales.

A high capacity square baler comprising a pickup mechanism configured to pick up a single windrow of crop material off the ground. The baler additionally comprising one or more stuffer chutes each configured to receive at least a portion of the crop material picked up by the pickup mechanism. The baler additionally comprising one or more stuffer assemblies each configured to push crop material generally upward through one or more of the stuffer chutes. The baler additionally comprising a plurality of bale-forming chambers each configured to receive crop material from one or more of the stuffer chutes. The baler further comprising a plurality of knotter assemblies each associated with one of the bales forming chambers and each configured to wrap and tie securement lines around each formed bale. The knotter assemblies are configured to operate independently of one another, such that formed bales can be tied at different times.
