A mowing finger arrangement has a lower element and an upper element connected to each other and forms two mowing fingers. A space is formed to accommodate a cutting device between the lower element and the upper element. The two mowing fingers are connected to each other via, respectively, a connection web on the upper element and on the lower element on a rear end of the mowing finger, when viewed in working direction. At least one of the connection webs has, at least portion wise, an off-set to provide an enlarged distance between the connection webs.

Mowing finger arrangement

A mowing finger arrangement and mowing bar for finger bar mowers of a harvester, as well as a method for manufacturing mowing fingers has an upper and lower element connected together to form at least one mowing finger.

A sieve for a thresher, especially a combine-harvester, for the separation of grain-like field fruits from stalk-like and chaff-like components has channels () extending parallel to a longitudinal axis (). The channels () are open to a first side A, from which they are loaded. The channels () are delimited by a bottomand laterally following flanks () which include openings (). Air guide following channels () are open to a second side B, which face away from the first side A. The two air guide channels () are arranged in a direction transverse to the longitudinal axis () and are separated by a continuous separation wall (). The separation wall () extends between two neighbouring channels () which extend parallel to the longitudinal axis (). In these separated air guide channels (), respectively, the openings () of only one of the two channels () separated by the air guide channels () are open.
