An agricultural harvester includes a chassis, a cleaning system carried by the chassis, and a crop material elevator for receiving crop material that has passed through the cleaning system. The crop material elevator has a top-most end, a bottom-most end, a first inlet between the top-most end and the bottom-most end, and a second inlet between the top-most end and the first inlet. The agricultural harvester also includes an auger system for supplying crop material from the cleaning system to the crop material elevator. The auger system includes a first auger defining an auger axis for supplying crop material to the first inlet, a second auger defining a second auger axis, and a crop material conveyor for supplying crop material from the second auger to the second inlet.

An agricultural harvester comprises a feederhouse pivotally attached to a chassis, where the feederhouse defines a conduit for conveying crop material rearwardly from a front opening. A header interface frame is pivotally mounted to the feederhouse over the front opening to permit header pitch adjustment around a pitch adjustment axis. Upper and lower linear actuators are connected on one side of the feederhouse between the feederhouse and interface frame to control the pitch adjustment.

A combine harvester includes a feederhouse mounted to a chassis. The feederhouse is adapted at a front end to support a crop gathering header in a manner that places a front inlet in communication with a discharge opening of the header. The feederhouse defines a crop conveying passage and includes a chain and slat conveyor arranged in the passage to convey a crop stream rearwardly from the front inlet over a floor. A longitudinally-aligned ridge is provided on the floor for dividing the crop stream.

A system and related method of applying forage treatment material to harvested forage is provided. The system can include a mobile forage harvester having a chute, a vacuum source that produces a vacuum, and a bin that stores granular treatment material for dispensation. The chute can be joined with a catch tube having a catch opening. A tube can extend from the bin toward the catch tube, but can be separated from the catch opening by an open gap. The material can be dispensed from the tube into the open gap, and drawn across the open gap and into the catch opening with the vacuum so the material mixes with the harvested forage moving along the pathway in the chute under force of the vacuum. The bin, tubes and the open gap can be located in an interior compartment to protect them from the elements. A related method is provided.

A bubble up auger includes a tubular housing, a screw auger and a baffle. The tubular housing includes an inlet opening having a first width end adjacent a first end of the tubular housing and a second width end opposite the first width end. The baffle extends from the inlet opening, outwardly from the central longitudinal axis of the tubular housing and towards the first end of the tubular housing.

A feederhouse assembly (200) for an agricultural harvester (100) includes a feederhouse (200) having an inlet end (204), ea yaw frame (214) adjacent the inlet end (204) and arranged to pivot about a vertical axis (216) relative to the feederhouse (200), and at least one hydraulic cylinder (220) configured to apply a hydraulic force to rotate the yaw frame (214) about the vertical axis (216). A method of connecting a harvesting header to an agricultural harvester includes applying a first hydraulic force from at least one hydraulic cylinder to a yaw frame (214), moving the agricultural harvester toward the harvesting header, securing the harvesting header to the yaw frame (214), and applying a second hydraulic force from the at least one hydraulic cylinder to the yaw frame (214) to orient the harvesting header at a right angle with respect to a longitudinal axis of the agricultural harvester (100).

The invention relates to a self-propelled harvesting machine comprising:—a removable harvesting unit (6) which can be mounted at the front in the direction of travel (F);—a processing unit in the interior; and—a harvested material conveyor channel (5) connecting said harvesting unit, when mounted, to the processing unit. According to the invention, the self-propelled harvesting machine is characterised in that a receiving space which at least partially receives said conveyor channel when in the harvesting mode can have its width adjusted transversely to the direction of travel.

An agricultural combine including an agricultural harvester, a crop tank for harvested material, and an unloading auger assembly for unloading and discharging crop material. The auger assembly has inner and outer auger tubes pivotally connected to one another. The auger tubes pivot between a first position in which the auger tubes extend transversely and are coaxial and a second position in which the auger tubes form an angle. The auger tubes contain augers having first and second couplings at cooperating ends. The first coupling has two projections extending to cooperate with a single radial projection on the second coupling to provide improved engagement.

A feederhouse for a combine harvester comprises an endless conveyor having at least two traction means made of inherently flexible material circulating about the deflection rollers and offset from one another in the axial direction of the deflection rollers, between which conveying strips extend. The inner sides of the traction conveying strips are furnished with cams made of inherently flexible material. Anchor plates are embedded in each of the cams. A first fastener having a first head recessed within the individual cam extends through individual cams, through individual anchor plates and through individual conveying strips. The anchor plate comprises two non-circular openings, wherein the first fastener and the second fastener each have non-cylindrical outer circumferential surfaces received within the non-circular openings to inhibit rotation of each of the first fastener and the second fastener relative to the anchor plate.

An inclined conveyor for a combine harvester has two drive elements which define a conveying direction and revolve in a conveying duct. Conveying duct is divided into an overshot return duct and an undershot conveying duct by a separating element situated between the upper run and the lower run of the drive element. Drive element is interconnected by carriers situated transversely with respect to conveying direction that convey harvested crop in undershot conveying duct. The difference in speed between the carrier bars and harvested crop stream is eliminated, and at least reduced, by additional acceleration of harvested crop stream. Carrier bars serve as carriers, and as acceleration elements for the harvested crop. That is because the cross section of each of the carrier bars viewed in conveying direction, occupies at least 30% of the smallest internal cross section of undershot conveying duct.
