  • Patent number: 8955298
    Abstract: 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.

  • Patent number: 8806845
    Abstract: 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. The mowing finger arrangement serves to guide a mowing sickle and forms counter cutting edges for the sickle blades arranged on the mowing sickle. An abutment on the upper element delimits upward movement of the mowing sickle when a downward force is exerted on the face end of the sickle blades.

  • Patent number: 8464506
    Abstract: A mowing finger arrangement has a lower element (4) and an upper element (3). The lower (4) and upper (3) elements are connected to each other and form two mowing fingers (1, 2) and a blade gap (15). The blade gap (15) guides a mowing sickle between the lower element (4) and the upper element (3). The lower element (4) forms lower counter cutting edges (20, 21). The upper element (3) forms upper counter cutting edges (22, 23) for the mowing sickle. The two mowing fingers (1, 2) are connected to each other via a rear (26) and a front (29) connection web on the upper element (3) and via a rear (35) and a front (34) connection web on the lower element (4). The two front connection webs (29, 34) of the lower element (4) and the upper element (3) define part of the blade gap (15).

  • Patent number: 7104882
    Abstract: 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 (2, 2a, 2b) extending parallel to a longitudinal axis (1). The channels (2, 2a, 2b) are open to a first side A, from which they are loaded. The channels (2, 2a, 2b) are delimited by a bottom 3 and laterally following flanks (4, 5) which include openings (9). Air guide following channels (10, 11) are open to a second side B, which face away from the first side A. The two air guide channels (10, 11) are arranged in a direction transverse to the longitudinal axis (1) and are separated by a continuous separation wall (13). The separation wall (13) extends between two neighbouring channels (2, 2a) which extend parallel to the longitudinal axis (1). In these separated air guide channels (10, 11), respectively, the openings (9) of only one of the two channels (2, 2a) separated by the air guide channels (10, 11) are open.
