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.

An agricultural baler includes a baling chamber with a plunger that is provided to reciprocally move in the baling chamber. The baler further includes a pre-compression chamber with a slice pushing mechanism provided for periodically pushing a slice of crop material into the baling chamber. The plunger and the slice pushing mechanism are mechanically linked via respective driving systems to ensure synchronization, wherein a coupling is mounted in the mechanical link to adjust a synchronization timing.

A square baler including a baling chamber having a floor formed of spaced profiles, side walls and a top wall, and a density belt surrounding the baling chamber. The density belt is formed of a U-shaped frame having three beams welded to one another to define a floor beam for supporting the floor of the baling chamber and two upright beams for supporting the side walls of the baling chamber and a tensioning rod releasably secured to the upper ends of the two upright beams to prevent the upright beams from splaying apart.

A bale identification assembly has a binding material with identification tags at spaced intervals is used by a knotter system to bind a formed bale. A read module with an antenna transmits interrogator signals and also receives authentication replies from identification tags. The bale identification assembly has a bale drop sensor with a paddle. As a completed bale passes through the discharge chute, the completed bale interacts with the paddle causing the bale drop sensor to activate. Activation of the bale drop sensor activates the antenna for a specified active cycle, and during its active cycle, the read module assigns any identification tag that is sensed to the completed bale that is leaving the discharge chute. A controller receives information from at least one crop sensor and/or bale sensor and associates the information about the completed bale with the identification tag on the completed bale.

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 improved belt tensioning system for an agricultural round baler that increases belt tension to reduce slippage between the belts and the driving rolls during the initial stage of a bale forming cycle when the bale chamber is empty and as the belts are beginning to be rolled. The system includes an accumulator that is pressurized by the tensioning system as a bale is being formed. The accumulator pressure may then be directed to a hydraulic cylinder included in a bale density system to increase tension in the belts after a completed bale is ejected and the bale chamber is being reset for the next bale.

A method and system for determining bale properties of crop material bales includes transmitting a first microwave signal through a bale of crop material located within an agricultural baler at a first frequency and transmitting a second microwave signal through the bale of crop material at a different second frequency and calculating, with at least one computing device, a phase angle displacement between the first and second microwave signals and determining, with the at least one computing device, a bale property of the bale of crop material based at least in part on the calculated phase angle differential.

A bale compression device for receiving and compressing a bale of material. The device includes a press configured to compress the bale of material to a required compressed dimension, a binding applicator configured to apply a plurality of bindings around the bale of material prior to the bale being compressed, and a connector for connecting ends of each of the bindings to form a plurality of complete loops around the perimeter of the bale so that the plurality of loops act to hold the bale in a compressed state. The binding applicator acts to withdraw excess binding as the press compresses the bale, prior to the connector connecting the ends of each of the bindings, such that the complete loops are formed when the bale reaches its required compressed dimension.

A method of controlling the weight of bales made by an agricultural baler. The method includes: receiving a bale weight setpoint; receiving crop parameter data; and, while a bale is being made: receiving baler operating data relating to baling parameters; inputting the crop parameter data and baler operating data into a weight prediction model to generate a predicted final weight of the bale; and changing a baling parameter setpoint of one of the baling parameters based on the predicted final weight of the bale and the bale weight setpoint.

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.
