Abstract: A header for an agricultural vehicle. The header includes a header frame and an elongate sickle knife mounted along a leading edge of the header. The header further includes an actuator for reciprocally moving the elongate sickle knife in its longitudinal direction relative to the header frame between a first position and a second position over an intermediate position. At least one accumulator extends between the header frame and the elongate sickle knife to accumulate energy during a first movement of the elongate sickle knife from the intermediate position towards at least one of the first position and the second position, and to release accumulated energy during a second movement of the elongate sickle knife opposite to the first movement.

Abstract: In a sickle cutting system, it has been found that a significant decrease in cutting inefficiency, which is measured by calculating the area of the cutting process where crop is not immediately cut but is instead pushed forwardly by engagement with a surface of the system, can be obtained by a combination of one or more of the features where the cutting stroke is reduced from the conventional length of 3.0 inches to a value of the order of 2.0 inches; the length of the cutting edge of each knife blade is increased to a length greater than 2.2 inches; the width at the rear of the ledger surface of each guard is increased to greater than 1.0 inches; and the front edge of the blade is formed with an apex to shed crop material to one or other side of the apex.

Abstract: In a sickle cutting system, it has been found that a significant reduction in average stubble length, which is calculated based on the distance crop is pushed forwardly without cutting occurring, can be obtained by a combination of one or more of the features where the cutting stroke is reduced from the conventional length of 3.0 inches to a value of the order of 2.0 inches; the length of the cutting edge of each knife blade is increased to a length greater than 2.2 inches; the width at the rear of the ledger surface of each guard is increased to greater than 1.0 inches; and the front edge of the blade is formed with an apex to shed crop material to one or other side of the apex.

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).

Abstract: A mowing finger for finger bar mowers of harvesting machines having first and second opposing finger parts each formed of flat material. The first and second finger parts are fixedly secured to each other to define a gap therebetween for mowing action between them. The mowing finger has a tapered front portion located forward of the blade gap and a rear portion secured to a finger bar. One of the first or second finger parts includes a twisted portion twisted around the longitudinal axis of the mowing finger and fixedly secured to the other end of the finger parts to provide increased rigidity to the mowing finger. At least one vegetation-excluding deformation is formed in the first or the second finger parts in the area of the blade gap and extends into the blade gap to narrow and obstruct the blade gap against the accumulation of plant matter therein.

Abstract: A knife guard filler finger assembly is provided with a mounting plate, rearwardly opening slots in the mounting plate which are positionable over bolts and beneath the lugs of original equipment fingers, the bolts securing the mounting plate to the cutting platform of a harvester, and fingers which project forwardly of the mounting plate and are located between the original equipment fingers of a harvester cutter platform. When fitted to a cutting platform, the filler fingers are generally positioned between, and at the same level as, the existing knife guard fingers.

Abstract: The present invention is an improved cutter guard having means for positioning the guard in either a first position or a second position upon a respective cutter bar assembly. The positioning means includes a pair of partially overlapping openings aligned along an axis. The overlapping areas of the pair of openings define a reduced passageway which prohibits a bolt inserted into one of the openings from moving across the overlapping areas into the other opening.

Abstract: Pointed shear fingers are formed, preferably in multiples, from a flat metal plate which is blanded out to the required outline. The blank is formed in a die which offsets the projecting finger portions and simultaneously creates a convexity of the bottom surface bordered by angled edges or bevels, the forming also producing a concavity in the top of each finger, leaving a flat V-shaped marginal portion which provides shearing edges in conjunction with the formed bevels of the bottom side. Shear fingers are separated by clean-out recesses which are formed in the blanking operation.
