A cleaning system for an agricultural harvester includes: at least one sieve; a cleaning blower directed at the at least one sieve and configured to supply a cleaning air flow directed at the at least one sieve; and a conveyor assembly configured to supply crop material to the at least one sieve. The conveyor assembly includes: a conveyor frame; a shaker coupled to the conveyor frame and configured to shake the conveyor frame; and an endless conveyor carried by the conveyor frame and including a conveyor loop with a substantially solid surface and a conveyor driver coupled to the conveyor loop, the conveyor driver being configured to selectively rotate the conveyor loop.

Pickup belt headers may include a ramp disposed in a gap formed between a first endless belt of a pickup belt assembly and a second endless belt of a transfer belt assembly. Fingers may be provided on the first endless belt, and the fingers may be deflected, such as by pivoting or bending, in response to engagement between the fingers and the ramp to avoid contact between the fingers and the second endless belt.

A header for a combine harvester includes a conveyor belt for conveying crop material in a conveyance direction, and an adjusting device for adjusting a tension of the conveyor belt. The adjusting device includes a cable that is movable with respect to a frame member of the header. A portion of the cable that is either directly or indirectly attached to one end of a roller for the conveyor belt extends either parallel to or substantially parallel to a tensioning direction of the conveyor belt for adjusting the tension of the conveyor belt. The conveyor belt may be an infeed conveyor belt or a lateral conveyor belt of a draper header, for example.

A draper head has a draper head frame and an attachment frame for connection to a feeder housing of a harvester. The draper head frame is connected to swing arms facing in working direction and having front ends movable vertically. The front ends of the swing arms are connected to a blade angle section provided with cutting elements. A center draper belt frame is pivotably arranged at the draper head frame and has a center draper belt disposed thereat. Transverse conveyor belts convey crop transversely to the working direction to the center draper belt which conveys crop rearwardly toward a discharge opening of the draper head. A rotary conveyor is arranged upstream of the discharge opening for conveying the crop toward the discharge opening. A rotation axis of a rearward shaft of the center draper belt and a rotation axis of the center draper belt frame are concentrically arranged.

A harvester has a main frame defining a front and a rear, and an inlet for receiving first portions of a crop. The inlet is disposed proximate the front of the main frame. The harvester also includes a separator for processing the first portions, at least one outlet downstream of the separator for ejecting the processed first portions, a boom extending proximate the front of the main frame for reaching un-processed crop, and a topper coupled to the boom for cutting second portions of the crop. The topper includes a cutter for cutting the second portions, a conveyor for receiving the second portions from the cutter, and an outlet disposed proximate the conveyor. The conveyor is configured to transport the second portions towards the outlet for ejecting the second portions towards the field.

A coupling mechanism for coupling a crop conveyor unit 15, for creating a swath behind an agricultural machine, to a mounting structure 10 attached to an agricultural operating unit, e.g. a mower 21. The coupling mechanism consists of gendered elements 65/66, at least one of which is tapered, such that the connection is self-guiding into the engaged configuration. A quick coupling method is described where the conveyor unit 15 is rolled on wheels to locate the male element 11 underneath the female element 12. The mounting structure is raised such that the male element engages the female element and optional locking pins secure the engaged parts together. Quick de-coupling is performed by reversal of the coupling method.

Two-sided cleaning arrangements for an endless belt for an agricultural header are disclosed. An endless belt with a two-sided cleaning arrangement may include a crop carrying surface and first and second cleaning features disposed in first and second edge regions, respectively, of the endless belt. The first and second cleaning features may extend above or be recessed below the crop-carrying surface.
