A woody biomass baler having a baling chamber adapted to receive woody biomass material and a compression system adapted to compact the material into a parallelepiped bale in the baling chamber, wherein the baling chamber has a front wall that acts as a reciprocating compression platen corresponding in dimensions to the width W and height H of the bale, opposing upper and lower walls corresponding in dimensions to the length L and either of the W and H of the bale, and opposing sidewalls corresponding in dimensions to the L and the other of the W and H of the bale, and wherein each chamber wall selected from among the upper wall, the lower wall, and each of the sidewalls can withstand a distributed force perpendicular to the selected chamber wall of between (0.11Pp psiAw) pounds and (0.3Pp psiAw) pounds, wherein 0.11 and 0.3 are Poisson's ratio values, Pp is the maximum pressure that the compression system can apply to woody biomass material in the chamber, and Aw is the area of the selected chamber wall expressed in square inches.

An agricultural baler including a baling chamber and a pre-compression chamber, the baling chamber including at least one movable wall. The agricultural baler further includes multiple sensors and a controller adapted for controlling operation of the agricultural baler based on inputs of the multiple sensors, wherein a first subset of the multiple sensors is related to a first feature and a second subset of the multiple sensors is related to a second feature. The controller is configured to control the operation of the agricultural baler in a first time period until the first feature is within a first predetermined range, and to control the operation of the agricultural baler in a subsequent time period, until the second feature is within a second predetermined range.

An agricultural baler with a pre-compression chamber configured to introduce a slice towards a baling chamber. The baling chamber includes a plunger provided for reciprocally moving in the baling chamber, the reciprocal movement having a power movement. In use, during the power movement, slices of crop material are compressed into a bale and the bale is pushed through the baling chamber. The baling chamber further includes at least one movable wall for exercising a compression force to the crop material in a direction transverse to the propelling movement so that, in use, the at least one movable wall provides a counter pressure for the propelling through the baling chamber of the bale. The agricultural baler further includes a controller adapted to influence a compression force of the at least one movable wall at a predetermined moment of the power movement to reduce the counter pressure.

An agricultural baler includes a hydraulic circuit with a first hydraulic cylinder connected between the first end of the first axle and the chassis, and a second hydraulic cylinder connected between the second end of the first axle and the chassis. At least one sensor senses a position of the chassis relative to the first axle. An electrical processing circuit is coupled with the hydraulic circuit and the at least one sensor. The electrical processing circuit controls operation of the hydraulic circuit, and includes an operator input device for selectively: 1) raising the chassis of the baler relative to the first axle, 2) lowering the chassis of the baler relative to the first axle, or 3) automatically returning the chassis of the baler to a predetermined operating height relative to the first axle, dependent upon an output signal from the at least one sensor.

A baler implement may include a frame, a first panel, a plunger, and a hook mechanism. The frame has a central longitudinal axis. The first panel partially forms a compression chamber for compressing crop therein. The plunger is operable to reciprocate within the compression chamber to provide a compressive force to compress crop material in the compression chamber into a flake against a plurality of other flakes of a currently forming bale and is operable to move the currently forming bale through the compression chamber. The hook mechanism is positioned on the first panel and is operable to engage the currently forming bale inside the compression chamber to resist the compressive force applied by the plunger to increase compression of the crop material within the compression chamber.

A baler including a baling chamber that includes a bale-forming channel including an inlet end and an outlet end, a plunger mounted within the channel for compressing bale material in the channel and driving the compressed bale material towards the outlet end of the channel, and a rotary drive mechanism for driving reciprocating movement of the plunger, and an additional drive mechanism for driving the compressed bale material towards the outlet end of the channel, thereby reducing torque in the rotary drive mechanism.

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.

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.
