A threshing mechanism is formed with a first threshing drum and a second threshing drum disposed one behind the other in a direction of crop flow. A first concave encloses the first threshing drum and the second threshing drum in sections in a circumferential direction. A second concave encloses the second threshing drum in sections in the circumferential direction. The concaves are displaceable in a radial direction of the threshing drums and are formed with at least one crop-processing device disposed at the first concave. The first concave and the second concave are swivellable about a common axis connecting the concaves. The enclosure of the second threshing drum by the first concave and the second concave is approximately identical.

A combine harvester includes a separating device that extends in a longitudinal direction of the combine harvester. In front of the separating device, a tangentially disposed feed drum is installed. The feed drum is configured with substantially axially parallel guide plates on a circumference thereof. The substantially axially parallel guide plates bear against the jacket surface of the feed drum via support elements. The support elements extend between adjacent guide plates in the circumferential direction and, extend between the adjacent guide plates in the radial direction across an entire free jacket surface of the feed drum.

Combine harvester with transverse feed drum

A self-propelled combine harvester has a threshing mechanism composed of at least one aggregate selected from the group consisting of a threshing part, a working unit, and both, at least one stripping unit which is assigned to the at least one aggregate, and at least one rotary chamber configured on the at least one stripping unit on a circumference of the at least one aggregate.

A method for changing throughgoing openings on separation area of a concave in an agricultural harvester in which the concave is composed of at least one frame, a plurality of beater strips and wires together forming the concave separating area, arranging at least one adjusting device under the concave separating area, and adjusting a width of the throughgoing openings by the at least one adjusting device; and a device for performing the method is provided.

Round balers include bale shaping elements which define the boundary of the bale forming chamber. One part of the bale shaping elements can be swung by an attached structural arm into the bale forming chamber. The amount the elements are swung into the chamber is defined by the tensional forces on a spring. These tensional forces can be manually adjusted using a device, in a stepwise manner. One embodiment includes a handheld lever and a stepped shift-gate.

Baler with adjustable bale densities

The present invention relates to a round baler for agricultural crop material having a press chamber for pressing the crop material and a wrapping device for wrapping the fully pressed round bales of crop material, wherein the wrapping material is secured on a web roll. The web roll is provided with a brake rod acting on the outside diameter of the bale. The essential characteristics of the invention are that a brake rod is affixed to one lever arm of a two-armed pivot lever and the effective linkage point of a plurality of tension springs is positioned the other lever arm. The linkage point's position is automatically variable relation to a stationary pivot point of the pivot lever as a function of the respective diameter of the web roll.
