A bale chamber includes: movable density doors; at least one fluid cylinder including a fluid chamber, a piston separating the fluid chamber into a piston side and a rod side, a cylinder rod coupled to the piston on the rod side and configured to move at least one of the density doors, a piston fluid port, and a rod fluid port; and a fluid supply circuit fluidly coupled to the fluid chamber and configured to supply working fluid to the fluid chamber, the fluid supply circuit including a fluid supply controller that is selectively switchable to a first fluid supply mode and a second fluid supply mode, the fluid supply circuit being configured to supply working fluid to only the piston side when in the first fluid supply mode and to supply working fluid to both the piston side and the rod side when in the second fluid supply mode.

An agricultural baling machine including: frame; a connection point for attaching to a towing vehicle; a plunger in a bale-forming chamber; a driveline for taking power from the towing vehicle and causing reciprocal rectilinear motion of the plunger in the bale-forming chamber; and a drawbar assembly that provides a mechanical link between the connection point and the frame. The drawbar assembly includes: a lower drawbar member and an upper drawbar member, wherein both members extend in a longitudinal direction of the baling machine from the frame towards the connection point; and wherein the lower drawbar member is spaced apart from the upper drawbar member in a vertical dimension such that one or more components of the driveline are accessible from the side of the baling machine through the drawbar assembly.

An agricultural baler includes a main bale chamber extending in a bale forming direction from an inlet end to an outlet end. The main bale chamber includes a plurality of stationary walls and a plurality of movable density doors positioned downstream from the stationary walls, relative to the bale forming direction. The stationary walls include a ceiling, a first side wall and a second side wall. A plunger compresses and moves the crop material from the inlet end towards the outlet end of the bale chamber. The baler is characterized in that the first side wall, the second side wall and/or the ceiling comprises a constriction surface, which constricts the main bale chamber in a direction transverse to the bale forming direction.

An agricultural baling machine including: a frame; a connection point for attaching to a towing vehicle; a plunger in a bale-forming chamber; a driveline for taking power from the towing vehicle and causing reciprocal rectilinear motion of the plunger in the bale-forming chamber; and a drawbar member that provides a mechanical link between the connection point and the frame. The drawbar member is rotatably coupled to the frame such that the height of the connection point relative to the frame of the baling machine is adjustable.

A mobile baling machine including a rotary input shaft connected by way of a driveline to a rotatable flywheel; and a drive converter that converts rotation of the flywheel to reciprocal rectilinear motion of a plunger, in a bale-forming chamber forming part of the baling machine, in manner forming plant matter in the bale-forming chamber into a compressed form; the driveline including one or more clutches for controlledly transferring rotary drive between the input shaft and the flywheel, wherein the driveline includes a transmission including driveline components defining at least first and second selectable transmission ratios between the input shaft and the flywheel; and wherein the baling machine includes or is operatively connected to one or more controllers that selectively engage a relatively lower, first said transmission ratio or a relatively higher, second said transmission ratio in dependence on conditions prevailing in the baling machine.

The present invention generally relates to a baling press for baling cotton gin trash and other particulate biomass feedstock. The baling press generally comprises an infeed chute assembly, a compression ram assembly, an extrusion chamber assembly, a strapping storage and dispensing assembly, and a strapping insertion assembly. The present invention also relates to methods of producing a bale with the baling press and a bale generated by said baling press and described methods.

Herein described is an automatic bale strapping mechanism for dispensing, cutting, and securing strapping material around a bale of material being formed by a baling press. The automatic bale strapping mechanism can be an integral component or series of components to a conventional baling press. The bale strapping mechanism includes a draw and cutter assembly comprising a mobile draw carriage that draws strapping material a predetermined distance for cutting. The bale strapping mechanism can also include a dispensing mechanism which dispenses strapping material and an insertion assembly which carries strapping material through an extrusion chamber chute of a baling press. Also described are methods of automatically drawing and cutting strapping material.

An agricultural harvesting machine having a multiple stage compression system includes first and second compression systems. The first compression mechanism partially compresses the crop material in a compression chamber. The second compression system having first and second compartments each having at least one open end and positioned rearward of the compression chamber. The second compression system has a first position in which the first compartment is aligned with the compression chamber and the second compartment is operatively positioned with a second compression mechanism. The second compression system has a second position in which the second compartment is aligned with the compression chamber and the first compartment is operatively positioned with a second compression mechanism. The second compression system includes a binding system operatively associated with the second compression mechanism. At least one of the first and second compartments rotate between the first and second positions.

A system and method for packaging pine straw and a packaged mass of pine straw made therefrom, the method including providing an electronically-controlled system configured for packaging pine straw, the system including system logic that controls conveying, fluffing, cleaning, compressing and packaging of the pine straw, and using the system to compress a mass of pine straw into a rectangular mass of pine straw and enclosing the rectangular mass of pine straw within a flexible plastic sheet thereby forming a substantially rectangular packaged mass of compressed pine straw.

A bale wrap mechanism including a frame including a wrap chute formed from one or more perimeter walls, where the wrap chute includes a wrap axis extending longitudinally therethrough, and where the one or more perimeter walls at least partially define a passageway, a first rail fixedly coupled to the frame, a first shuttle movable along the length of the first rail, where the first shuttle includes a second rail that is transverse to the first rail, a second shuttle movable along the length of the second rail, wherein the second shuttle includes a mounting point, and a shaft coupled to the mounting point, where the shaft is configured to rotatably support the roll of wrap material thereon, and where the shaft is configured to travel along a wrap path during a wrapping process, where the wrap path surrounds the passageway, and where the wrap path is non-circular in shape.
