A feeder for a combine harvester. The feeder includes a housing and a conveyor assembly mounted in the housing. The conveyor assembly includes a frame having lateral support arms, and moveable belts guided by sprocket wheels. The sprocket wheels are mounted on a drive shaft proximate an outlet section of the housing and on a conveyor shaft proximate an inlet section of the housing. The sprocket wheels are mounted on a drive shaft proximate an outlet section of the housing and on a conveyor shaft proximate an inlet section. The conveyor assembly is equipped with a first and second tensioning mechanism, the first mechanism being configured to push the conveyor shaft forward with respect to the frame, the second mechanism including spring-operated tensioning arms and tensioning rolls mounted above the support arms.

A first threshing section 15 and a second threshing section 16 are provided. The first threshing section 15 includes a first threshing drum 17 that rotates about a left-right-oriented axis, and the second threshing section 16 includes a second threshing drum 28 that rotates about a body front-rear-oriented axis. The second threshing drum 28 includes a rotary support shaft 29 extending along a front-rear direction, a plurality of rod-shaped frame bodies 30 that are arranged side by side extending along the front-rear direction and at and interval in the peripheral direction, radially outward of the rotary support shaft 29, and threshing teeth 31 attached to the frame bodies 30.

An agricultural harvester includes a threshing assembly configured to thresh crop material received from a feeder of the agricultural harvester. The threshing assembly, in turn, includes a concave and a rotor positioned relative to the concave such that a gap is defined between the concave and the rotor. Furthermore, the agricultural harvester includes an actuator configured to move the concave relative to the rotor to adjust a size of the gap. Additionally, the agricultural harvester includes a tailings assembly configured to receive incompletely threshed crop material that has passed through the concave. Moreover, the agricultural harvester includes an imaging device configured to capture image data depicting the incompletely threshed crop material present within the tailings assembly and a computing system communicatively coupled to the imaging device. As such, the computing system is configured to determine an amount of the incompletely threshed crop material present within the tailings assembly based on the captured image data. In addition, the computing system is configured to control an operation of the actuator based on the determined amount of the incompletely threshed crop material present within the tailings assembly.

A combine crop trash removal system for mounting to a combine corn harvester using hydraulically driven air blowers coupled to the combine header control system for reduction and/or removal of stalks, leaves, dirt and dust type material from accumulating on the combine feeder house and obscuring the operators view of the operating combine header during operation of the combine harvester for corn picking. The air blower may also be driven electrically or pneumatically. The operator of the combine harvester controls the crop trash removal system from the operator cab of the combine harvester.

A combine harvester includes a rotor cage surrounding a rotor, a threshing space defined between the rotor cage and the rotor, and a transition section defining an infeed to the rotor cage. The transition section is mounted to the rotor cage at a location upstream of the rotor cage. The transition section has an inlet for receiving the crop material. The harvester also includes a crop conveying drum for conveying crop material to the inlet of the transition section and beneath the rotor. The crop conveying drum is at least partially encased by a shroud. The transition section includes a bottom wall, two side walls each having lower portions extending substantially vertical with respect to the bottom wall, and curved side walls each extending between the bottom wall and one of the side walls. The bottom wall is substantially tangential to a lower portion of the shroud.

A header for an agricultural harvester including an infeed conveyor having a fore end and an aft end, a center knife drive disposed adjacent to and forwardly of the infeed conveyor, and a knife drive cover covering the center knife drive. The knife drive cover includes a main body substantially covering an entire width of the center knife drive, and a seed saver extending rearwardly from an aft end of the main body. The seed saver is substantially planar, includes a width substantially the same as a width of the infeed conveyor, and defines a plane substantially parallel to a longitudinal axis of the infeed conveyor. The seed saver is integrated with the knife drive cover. As such, the seed saver is secured to the header without need for metal brackets and other associated mounting hardware.
