A feeder unit for an agricultural baler includes: a first rotor including a plurality of first extensions extending therefrom, the first rotor being configured to rotate about a first axis of rotation at a first rotation speed; and a second rotor arranged in parallel with the first rotor relative to the axis of rotation and including a plurality of second extensions extending therefrom that intermesh with the plurality of first extensions, the second rotor being configured to rotate about a second axis of rotation at a second rotation speed that is different from the first rotation speed.

A control system for controlling a cutting operation performed by at least one controllable components of an agricultural baler on a wrapping material incorporating a plurality of electronic identifiers is disclosed. The control system ensures that an electronic identifier is not damaged when the cutting operation is performed.

An agricultural system including an agricultural baler and a control unit. The agricultural baler includes a pick-up arrangement for collecting plant matter. The pick-up arrangement includes a roller for feeding crop into the baler. The baler further includes a pick-up drive shaft for moving the roller at a desired rotational speed. The pick-up drive shaft is connected to the roller by a clutch for selectively transferring power between the pick-up drive shaft and the roller. The control unit is configured to: receive clutch-status-data indicative of an engagement status of the clutch; determine a speed-control-signal for varying the rotational speed of the pick-up drive shaft based on the clutch-status-data; and provide the speed-control-signal to a driveline for driving the pick-up drive shaft.

A crop cutting device including a crop guiding surface including parallel slots. A row of knives pivotally mounted below the guiding surface is pivotable between a retracted inoperative position in which it is located below the guiding surface and an extended operative position, wherein the knives project above the guiding surface. An actuating mechanism includes movable operating members. Each operating member is associated with a respective knife and is movable from a first position in which the knife is in its retracted position to a second position in which the knife is in its extended position. Further, there is included a lifting mechanism for raising at least a part of each knife above the guiding surface, while the operating members are in their first position.

A baler includes a housing forming a baling chamber. The baling chamber has an inlet that defines an inlet width perpendicular to a central longitudinal axis of the baler. A pre-cutter is disposed forward of the inlet along the central longitudinal axis and includes a cutter width perpendicular to the central longitudinal axis. The cutter width is substantially less than the inlet width. A crop distributor is disposed between the pre-cutter and the inlet and conveys the crop material from the pre-cutter to the inlet. A pick-up head is disposed forward of the pre-cutter and lifts the crop material from the ground and conveys it to the pre-cutter.

A shredding and baling apparatus provided includes a shredding assembly operatively connected to a baling assembly via a conveyor. A rotatable drum with cutting teeth spirally arranged along the drum is preferably centered within a lower portion of an intake hopper for cutting through material as it is fed into the hopper. Fixed cutting teeth are preferably arranged in a row or rows along each of the longitudinal sidewalls of the hopper, adjacent the cutting drum. A touch screen display and computer may be used in combination with sensors to monitor and control the shredding and baling operation, and a hydraulic system is used to drive the components. The shredding and baling assembly is preferably designed in an industrial size to handle high volumes of material and may be driven or transported from one location to another.

A baler for hay, straw, grass, and similar feed materials is provided. The baler communicates compressed material from a vertically inclined compression passage formed in between opposing conveyer belts to a central area of a baling chamber for baling. A plunger within the baling chamber can reciprocate in two directions to form bales which are tied and discharged from both ends of the baling chamber.

Baling apparatus including a baling chamber having a splitting knife for dividing crop material picked up from a field to discharge divided bales simultaneously. Bale depth control means allows production of bales of predetermined selected depths (or widths) by repositioning the roof of the baling chamber, using extensions to alter the crop-engaging surface of a plunger movable in the baling chamber and repositioning the splitting knife.

A conveyor for a baler has a feed bar with first and second bar parts connected by a coupling such that, from a stop position, the bar parts are rotatable relative to each other in a rotational direction against a restoring force and coupled to each other in the stop position to prevent rotation in opposite rotational direction. The conveyor conveys crop within a collection chamber toward a press chamber in collection mode and from the collection chamber into the press chamber in feed mode by feed tines of the first bar part. The conveyor guides the first bar part in collection mode by a feed collection lever of the second bar part and by force transmission via the coupling and guides the first bar part in feed mode partially by a feed lever of the first bar part by rotating the bar parts relative to each other.

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.
