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 large square baler includes a frame and a baling chamber for forming a bale. A support beam is attached to the frame and extends to a distal second end. A support structure is attached to the second end of the support beam. A track is attached to the support structure and includes an endless loop defining a path. A rotational drive is attached to the support structure and includes a crank rotatable about a rotation axis. An arm is coupled to the crank and includes an elongated slot. A carriage is attached to the arm and moves on the track along the path. The carriage supports a transverse face wrap roller for wrapping the transverse faces of the bale. A portion of the crank extends through and is moveable within the elongated slot such that a distance between the carriage and the rotation axis is variable.

A bale binding mechanism is configured to form crop material into a bale. The bale binding mechanism includes a baling needle and a twine tensioner. A baler chassis presents a baling chamber in which the bale is formed. The baling needle is shiftable up and down relative to the baling chamber, with the needle being shiftable to advance twine upwardly along an end of the bale. The twine tensioner is configured to maintain tension on a tensioned twine section extending between the twine tensioner and the needle, with the tensioned twine section defining a twine feed axis. The twine tensioner includes a tension device that restricts upward advancement of the tensioned twine section. The twine tensioner also includes a shiftable guide element. The guide element is shiftable into and out of a twine feed position associated with upward advancement of the tensioned twine section, with the guide element operable to define an offset twine section offset from the twine feed axis in the twine feed position. The twine tensioner includes a cutting device that severs the offset twine section when a twine over-tension condition causes the guide element to shift out of the twine feed position toward the twine feed axis.

A bale binding mechanism is configured to wrap twine around a bale of severed crop material. The bale binding mechanism broadly includes a baling needle, a twine tensioner, and a sensor. A baler chassis presents a baling chamber in which the bale is formed. The baling needle is shiftable up and down relative to the baling chamber, with the needle being shiftable to advance twine upwardly along an end of the bale. The twine tensioner is configured to maintain tension on a tensioned twine section extending between the twine tensioner and the needle, with the tensioned twine section defining a twine feed axis. The twine tensioner includes a tension device that restricts upward advancement of the tensioned twine section. The twine tensioner also includes a shiftable guide element. The guide element is shiftable into and out of a twine feed position associated with upward advancement of the twine section, with the guide element operable to define an offset twine section offset from the twine feed axis in the twine feed position. The sensor is operably associated with the guide element to sense guide element movement corresponding to a twine over-tension condition, with the bale binding mechanism restricting twine from being passed out of the twine tensioner in response to the sensed twine over-tension condition.

A knotter system for a baler includes a needle and a tucker arm for delivering a needle twine and tucker twine respectively, a twine receiver for holding the needle and the tucker twine, a billhook assembly including a billhook with a lower and an upper lip being mounted rotatably around an axis and being arranged for receiving the needle and the tucker twine, a twine finger for guiding the twine. Further, a driver is foreseen to make the billhook perform a first full rotation during the first knot forming cycle and a second full rotation during the second knot forming cycle. The knotter system is configured such that, at the end of the second knot forming cycle, a bale movement of a bale in the baler exerts a pulling force on the twines which removes the twines from the billhook.

A wrapping system includes: a material roll configured to hold a roll of wrapping material; a knife assembly comprising a movable knife that is configured to cut wrapping material that comes off the material roll; a sensor associated with the material roll and configured to output a drawn material signal; and a controller. The controller is configured to: receive the drawn material signal; determine a length of wrapping material that is drawn from the material roll; output a cut signal to the knife assembly when the drawn length of wrapping material reaches a defined length; determine a length of wrapping material that is drawn from the material roll after outputting the cut signal; and output an excessive wrap signal when the length of wrapping material drawn after outputting the cut signal exceeds a threshold length.

A mistie detection system comprising a baler configured to form bales from crop material. The baler includes a least one baling chamber configured to compress crop material into bales and at least one knotter assembly configured to tie securement lines around the bales. The system additionally includes one or more image sensors mounted to the baler and configured to monitor one or more of the knotter assembly, the securement lines, and the bales. The system further includes a control system configured to receive image data from the image sensors to determine if a mistie event has occurred.

A device and a method for attaching a label for identifying a bale to an elongate flexible object, wherein the device comprises storage means for the label and attachment means for attaching the label to the elongate flexible object, and wherein the label, on its edge, has an opening which is adapted to attach the label to the elongate flexible object.
