The disclosed invention provides an automatic, rotating agricultural system that rotates around a central pivot point in either a full rotation or a partial arc to irrigate, plant and/or harvest a field. The agricultural system includes a center pivot frame, a plurality of frame segments connected to each other, and a feed storage bin connected to the center pivot frame and the frame segments. The frame segment includes a section frame including wheels to enable movements, a cutter trolley beam extends in a radial direction of the section frame, a cutterhead coupled to the cutter trolley beam to cut forage or crop, a radial conveyor that moves the cut forage or crop in the radial direction of the section frame, and a cutter conveyor that moves the cut forage or crop from the cutterhead to the radial conveyor.

A crop cutting device including a crop guiding surface, a plurality of parallel knives, and an actuating mechanism for moving the knives between a retracted inoperative position below the crop guiding surface and an extended operative position. A portion of the knives projects above the crop guiding surface. A plurality of movable operating members is associated with respective ones of the plurality of knives and movable from a first position in which the knives are in the retracted inoperative position, to a second position in which the knives are in the extended operative position. A support frame holds the operating members in a sliding relation to the support frame. The knife insert assistant is coupled to the support frame and configured for blocking a sliding movement of the operating members relative to the support frame during a movement of the support frame from the retracted position to the employed position.

A harvesting machine comprises a crop conveying channel with a movable bottom flap coupled to a hydraulic actuator controlling the position of the flap and a crop throughput sensing arrangement with a pressure sensor adapted to sense a hydraulic pressure in the hydraulic actuator.

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 crop cutting device including knives pivotally mounted below a crop guiding surface. Each knife is pivotable between a retracted position in which it is located below the guiding surface and an extended position. At least a cutting edge of the knife projects above the surface. A selector mechanism selectively holds spring loaded parts of operating members to maintain the corresponding knife in its retracted inoperative position while the operating member is moved to its second position. The selector mechanism includes a shaft carrying a plurality of cam elements which are mounted on the shaft and arranged to be moved to a position for blocking a respective spring loaded part upon rotation of the shaft from a non-holding to a holding position.

An agricultural baler including a bale chamber; a feeder duct communicating with the bale chamber; and a feeder operable within the feeder duct to accumulate a charge of crop material therein and then stuff that accumulated charge into the bale chamber. The baler further includes a conveying channel and a conveyor operable in the conveying channel to convey the crop material along a bottom wall of the conveying channel toward the feeder duct. The bottom wall of the conveying channel is adapted to be moved away from the conveyor; and the lower end part of the bottom wall of the feeder duct is attached to the movable bottom wall of the conveying channel.

A large square baler for performing a baling operation to form square bales includes a pickup unit for picking up crop lying on the ground, a cutter unit for cutting picked up crop into at least one predetermined cut length, a pre-compression chamber, a stuffer device, a bale chamber for forming a square bale from flakes of crop pre-compressed in the pre-compression chamber, and a tying system for binding the square bale. The stuffer device is configured to pre-compress the crop into the flakes in the pre-compression chamber and transport the flakes into the bale chamber. The cutter unit is controlled in dependence on a tying operation conducted by the tying system and on at least one parameter representing the square bale size.

A conveying device (1) for picking up a sward of crop material from the ground and feeding the crop material to, for example, a baler (4), comprises a conveying channel (28) through which the crop material is conveyed from a pick-up mechanism (18) to the baler (4) by a feed rotor 34. The conveying channel (28) comprises a base (30) comprising an upstream base part (43) and a downstream base part (44). The upstream base part (43) is pivotal adjacent its upstream end (45) about a transversely extending first pivot axis (57). The downstream base part (44) is pivotal about a second transversely extending second pivot axis (76) towards the downstream end (51) thereof. The downstream end (46) of the upstream base part (43) is supported on a pair of first resilient mounting members (59) and the upstream end (50) of the downstream base part (44) is supported on a pair of second resilient support members (85) through a pair of carrier arms (78) which are pivotal about a transversely extending carrier pivot axis (74). The resilience of the first and second resilient support members (59) and (85) is such that on the force with which crop material is being urged by the feed rotor 34 against the upstream and downstream base parts (43) and (44) exceeding respective first and second predefined values, the first and second resilient support members (59) and (85) yield, thereby permitting downward displacement of the downstream end (46) of the upstream base part (43) and the upstream end (50) of the downstream base part (44) in order to permit crop material to pass through the conveying channel (28) without becoming jammed between the feed rotor (34) and the upstream and downstream base parts (43) and (44).

A crop cutting device including a crop guiding surface, a plurality of parallel knives, and an actuating mechanism for moving the knives between a retracted inoperative position below the crop guiding surface and an extended operative position. A portion of the knives projects above the crop guiding surface. A plurality of movable operating members is associated with respective ones of the plurality of knives and movable from a first position in which the knives are in the retracted inoperative position, to a second position in which the knives are in the extended operative position.

The knife insert assistant is coupled to the support frame and configured for blocking a sliding movement of the operating members relative to the support frame during a movement of the support frame from the retracted position to the employed position.

An agricultural baler including a bale chamber, a feeder duct communicating with the bale chamber for charges of crop material to be transferred from the feeder duct into the bale chamber; and a feeder operable within the feeder duct to accumulate a charge of crop material therein and then stuff that accumulated charge into the bale chamber. There is an opening in the bottom wall of the feeder duct and at least one door hingedly attached to an edge of the opening, the edge being the edge of an end part of the bottom wall of the feeder duct, and the end part of the bottom wall to which the door is hingedly attached, is movably arranged relative to the top wall of the feeder duct.
