There is a need for a combine harvester which may enhance the detection precision of a gain culm sensor by reliably bringing grain culms into contact with the grain culm sensor. The combine harvester includes: a harvest frame 11 that receives grain culms cut by a reaping device; a rake-in auger 12 that is disposed within the harvest frame 11 so as to be rotatable about a rotary axis X1 extending in a right/left direction of the harvester body, and that conveys the grain culms inside the harvest frame 11 in a right/left direction of the harvester body and rakes in the grain culms toward the rear of the harvester body; and a feeder 13 that is communicatively connected to a rear wall of the harvest frame 11, and that conveys the grain culms raked in by the rake-in auger 12 toward the rear of the harvester body. A grain culm sensor 25 that detects the presence of the grain culms when coming in contact with the grain culms is disposed at a grain culm feed port 24a in the feeder 13.

A combine unload control system having a grain tank for storing grain and at least one auger for unloading grain from the grain tank. The control system also includes a first auger cover proximate to the at least one auger, having one or more first auger cutouts disposed on a portion of the first auger cover and a second auger cover proximate to the at least one auger and having one or more second auger cutouts disposed on a portion of the second auger cover. The control system further includes a controller configured to control amounts of grain to pass through the one or more first auger cutouts and the one or more second auger cutouts and flow to the at least one auger by causing the first auger cover and the second auger cover to move relative to each other.

A crop pick-up header (2) according to the invention comprises a frame (10) and a rotatable reel (13) configured to collect crops from the ground, as well as a rotatable auger (20) provided with two oppositely wound helicoidal flights (26). The auger is rotatable about its central axis with respect to a pair of support arms (21) which are themselves pivotable relative to the frame, so that the pivoting movement of the arms results in lowering or raising the auger. The height position of the auger (20) is a function of the crop throughput and of the auger's rotational speed. The header of the invention is equipped with at least one sensor (30) configured to measure the height position of the auger or a parameter representative thereof. The header comprises or is coupled to a control unit (31) configured to control the auger's rotational speed as a function of the detected height position, determined through the sensor (30). In particular, the auger speed is lowered when the auger drops below a predefined height, so that lower throughput is compensated by a lower auger speed, thereby ensuring efficient chopping in a harvester to which the 20 header is coupled, even when the crop yield drops below a given level.

A header has a cutterbar table that is movably mounted to a frame and configured to cut a standing crop, an intake auger mounted to the frame and configured to receive the cut crop; the intake auger further being configured to rotate, during a normal state, in a predetermined direction, and to rotate, during a corrective state, in a predetermined reversed direction, an actuator assembly configured to displace the cutterbar table relative to the frame, thereby changing a distance between the cutterbar table and the intake auger, a control unit configured to, upon receipt of an error signal indicative of a need to operate in the corrective state control the actuator assembly to displace the cutterbar table away from the intake auger to a safe operating position, prior to controlling the intake auger to rotate in the predetermined reversed direction.

A Header for an agricultural harvester. The header includes a connector adapted to be connected to a feeder of the agricultural harvester. The header further includes a cutter bar and a first lateral crop transporting mechanism to move crop material towards a first opening at the connector. The header further includes a second lateral crop transporting mechanism provided at a distance from the first lateral crop transporting mechanism. The second lateral crop transporting mechanism is provided to move crop material towards a second opening at the connector, the second opening being different from the first opening.

An auger gap detection and control system for an agricultural harvester includes a controller including a memory and a processor. The controller is configured to receive a sensor signal indicative of an image of harvested crop material within a feederhouse of the agricultural harvester. The controller is also configured to analyze the image to measure a diameter of at least one ear of corn of the harvested crop material within the feederhouse. The controller is further configured to determine an initial size of an auger gap between an auger and a trough of a header of the agricultural harvester based on the diameter of the at least one ear of corn, the trough being located beneath the auger.

A bubble-up auger assembly for an agricultural vehicle includes an auger at least partially surrounded by an outer tube. A bracket is configured to be non-rotatably connected to a rockershaft of the agricultural vehicle for rotation about a first axis. A slide rod is connected to the outer tube and the bracket. The slide rod is configured to cause the auger to move between a raised position and a lowered position in response to rotation of the bracket. In the lowered position of the auger, an axis of rotation of the auger is oriented oblique to the first axis.

The stripper is a flange member supported on the upright backboard of a crop harvesting header to span a gap between the backboard and a cross auger. The cross auger is supported above a draper on the header to assist in guiding the cut crop being conveyed by the draper to a central rear discharge of the header. The stripper flange member extends forwardly towards the cross auger at an upward inclination so as to be oriented at an angle of greater than 90 relative to a portion of the backboard of the header immediately below the stripper flange member. The stripper flange member is thus better oriented to guide cut crop which rises up the backboard to be deflected forwardly into the cross auger, instead of acting as a stop to accumulate cut crop thereon when the flange member is oriented perpendicularly to the backboard.

A harvesting header has a set of centrally disposed conditioner rolls disposed in a center opening of the header configured to condition crop as the header moves across a field in a direction of travel. The harvesting header includes a cutter bed including a plurality of rotary cutters extending across the path of travel of the header, each rotary cutter being rotatable about an upright axis. At least one crop conveying spinner is mounted outboard the center opening on either side of the center opening. Each crop conveyance spinner has an upright disc having a plurality of paddles attached to a front face of the disc. The disc is mounted for rotation on a shaft, the shaft forming a spinner axis, wherein the spinner axis is perpendicular with the impeller axis.
