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 baler apparatus has a cylindrical bale-forming chamber defined by a set of compression elements positioned around the circumference of the bale-forming chamber, and drive means configured to drive rotary movement of the compression elements. At least one of the rotary compression elements is configured to provide a reduced level of traction relative to a bale in the bale chamber, as compared to at least the majority of the other rotary compression elements.

A pickup unit of an agricultural baler that includes a frame, at least one draper belt, at least one belt actuator operably connected to the at least one draper belt, a first auger and a second auger each being rotatably connected to the frame and located above the at least one draper belt, and a first and a second auger actuator respectively operably connected to the first and second auger. The pickup unit also includes an electrical processing circuit operably connected to and configured for adjusting the at least one belt actuator, the first auger actuator, and the second auger actuator so that a rotational speed of the at least one draper belt, the first auger, and/or the second auger is increased or decreased to evenly distribute the crop material as the crop material is transported to the bale chamber.

A system for controlling a position of a pickup on a baler comprises a sensor, a processing element, and a pickup pivot mechanism. The sensor monitors a ground area, senses a presence or absence of a windrow, and outputs a sensor signal with a first level and/or data value indicating the presence of the windrow and a second level and/or data value indicating the absence of the windrow. The processing element receives the sensor signal, and outputs a pickup signal with a first level and/or data value when the sensor signal has the first level and/or data value and a second level and/or data value when the sensor signal has the second level and/or data value. The pickup pivot mechanism receives the pickup signal, lowers the pickup when the pickup signal has the first value, and raises the pickup when the pickup signal has the second value.

A system for adjusting a tractor speed based on a performance of a pickup of a baler comprises a flow rate sensor, a processing element, and a tractor speed controller. The flow rate sensor senses a flow rate of a crop into the pickup and outputs a flow rate signal with a level that varies according to the flow rate of the crop into the pickup. The processing element receives the flow rate signal, receives a speed signal regarding a speed of a tractor pulling the baler, compares the flow rate from the flow rate signal with the speed from the speed signal to generate a comparison result, and outputs an electronic speed signal with a level that varies according to the comparison result. The tractor speed controller is configured to receive the speed signal and adjust a speed of the tractor according to the level of the speed signal.

An agricultural baler including a bale chamber; a plunger; a feeder duct; and a rotor feeder unit. The rotor feeder unit includes a rotor feeder unit bottom distant from a rotor feeder forming a lower boundary of a conveying channel through the rotor feeder unit. The rotor feeder unit also includes scrapers placed in a conveying direction behind the rotor feeder. The scrapers extend in between the tines and have a leading face cooperating with the tines. The agricultural baler further includes a position adjuster configured to displace the leading face of the scrapers relative to the rotor feeder unit bottom, and to displace a top wall and/or the bottom wall of the feeder duct, in order to adjust the volume of the feeder duct.

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.

The invention relates to an agricultural working apparatus for use in forage harvesting and to a corresponding method with tines rotating about an axis A with corresponding tine ends. A device for changing the distance between the tine ends and the ground is also provided, as well as a sensor device for measuring a stubble height. An evaluation unit, in particular a decision support system, is provided to which the sensor device supplies measurement signals for the stubble height and which can determine a position of the tine ends as a function of the measured stubble height. A control device controls the device for changing the distance of the tine ends in order to set the determined position of the tine ends.

An axle arrangement for a baler having a chassis includes a first axle having opposite ends and a pair of suspension cylinders, with each suspension cylinder positioned at a corresponding end of the first axle to accommodate generally vertical loads. The first axle is coupled with the chassis to accommodate generally horizontal loads. A second axle has opposite ends and a pair of suspension cylinders, with each suspension cylinder positioned at a corresponding end of the second axle to accommodate generally vertical loads. The second axle is coupled with the first axle to accommodate generally horizontal loads.
