  • 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: 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: 7757470
    Abstract: A tine carrier arrangement for a reel of a harvester for cereals has a tine carrier (1) rotatably attached on the reel around a rotational axis D. An adjustment element (3) is connectable to an adjustment arrangement of the reel for rotating the tine carrier (1) around the rotational axis D. The connection mechanism detachably connects the tine carrier (1) and the adjustment element (3) to each other to enable different rotational positions of the tine carrier relative to the rotational axis D.
