An agricultural harvester including a storage tank that includes a tank body and a tank cover assembly. The tank cover assembly has a travel state and an operational state. The tank cover includes a fabric wall element which is moveably connected to the tank body. In the operational state, the fabric wall element provides an upward extension of at least a part of the circumferential wall. In the travel state, the fabric wall element covers at least a part of the open top of the tank body. The fabric wall element includes a rigid area. The cover actuator assembly includes at least one cover actuator that is adapted to bring the tank cover assembly from the travel state into the operational state and vice versa, and to engage the fabric wall element at the rigid area.

A grain tank level sensing system for a combine which harvests grain. The combine includes an upwardly open grain tank fillable with harvested grain and a cover that is displaceable for closing off the open grain tank. An actuator displaces the cover between an open and close position and either single or dual ultrasonic sensors continuously detect the level of grain in the tank and generate a signal proportional to the level of grain in the grain tank. A control system receives the signal from the ultrasonic sensors and generates an indication of the level in the tank to a monitor and/or disables the actuator to initiate the closing function when the grain tank is full.

An elevator assembly for a harvester may include an elevator housing and an elevator extending within the elevator housing between a proximal end and a distal end. As such, the elevator may be configured to carry harvested crops between its proximal and distal ends. Furthermore, the elevator assembly may include a storage hopper extending from the elevator housing at a location adjacent to the distal end of the elevator. The storage hopper may include a conveyor extending within the storage hopper between a first end and a second end, with the conveyor configured to carry the harvested crops between its first and second ends towards a discharge opening of the storage hopper.

A combine harvester includes a threshing device 4 configured to perform a threshing process of threshing reaped grain culm in a threshing chamber 23, in which the threshing chamber 23 includes a threshing cylinder 31 configured to rotate around a front-rear axis X, and an arc-shaped receiving net 32 provided extending along an outer circumferential portion of the threshing cylinder 31, and a top plate 30 covering an upper portion of the threshing chamber 23 is supported detachably along the rotation axis direction of the threshing cylinder 31.

A harvester movable along a support surface. The harvester includes an inlet configured to receive crop, a blade configured to cut the crop into billet and extraneous plant matter, and a cleaning system configured to distinguish between billet and extraneous plant matter. Billet is directed toward a conveyor configured for discharging billet to a vehicle and extraneous plant matter is directed toward a hood. The hood includes a debris director defining an outlet configured to eject extraneous plant matter as residue onto the support surface. The outlet is disposed at an angle of residue ejection with respect to the support surface. The debris director is configured to adjust the angle of residue ejection with respect to the support surface.

An agricultural harvester includes a chassis and a grain tank carried by the chassis. The grain tank includes a frame having an opening formed therethrough; a pair of tank cover sections movably associated with the frame such that the tank cover sections can switch between an open position and a covering position relative to the opening of the frame; and at least one actuator linked to at least one of the tank cover sections and configured to selectively provide a switching force. The agricultural harvester further includes a force assistor or a brake linked to one of the pair of tank cover sections and configured to apply an assist force or a braking force, respectively, to one of the pair of tank cover sections but not the other of the pair of tank cover sections.

Disclosed is a grain harvesting articulated combine of a forward PPU, a rear grain cart, and an articulation joint that connects the forward PPU with the rear grain cart. The rear grain cart includes an ascending lift auger assembly that receives clean grain from the forward PPU and transports it upwardly for dumping into the rear grain cart. A generally horizontal drag auger assembly moves clean grain to a lower a lift auger assembly. A clean grain off-loading auger assembly is connected to the lower lift auger assembly by a slew bearing. The clean grain off-loading auger is retractable about its upper end and its upper end assembly is terminated with a spout adapted to direct clean grain generally downwardly. The clean grain off-loading auger assembly is rotatable from a grain off-loading position to a home position.

A combine that can accurately measure the weight of grain retained in a grain tank is provided. When a weight measurement signal is output from a measurement switch 66, a weight measurement decision unit 75 instructs a working state determination unit 71 to perform working state determination. If it is determined that the combine is in the working state, the weight measurement decision unit 75 does not instruct a load cell 39 to perform weight measurement.

A harvest analysis system, intended to be used in a machine (2, 3) for harvesting agricultural products, e.g. combine (2), forage harvester (3) or the like, comprising at least one image acquisition device (4, 40) and at least one processing unit (1), connected to said acquisition device (4, 40) and in turn comprising: at least one memory module (10) in which at least a first reference image is stored; and at least one comparison module (11, 12) configured to perform a comparison between the images of the harvested products, acquired by said device (4, 40) and said reference image.

A crop tank system has a crop tank for receiving harvested crop and a fill level sensor arrangement for detecting fill level information regarding the crop tank. The fill level sensor arrangement includes a radar sensor, which sends out and receives radar rays that, depending on the fill level of the crop contained in the crop tank, penetrate the crop contained in the crop tank and/or are reflected by the crop contained in the crop tank. The fill level sensor arrangement also includes an electronic sensor control, which determines the fill level information based on the received radar rays.
