Abstract: A mowing blade that performs an oscillating linear motion, has a blade bar, with at least two bar sections that are located one behind the other along a longitudinal axis. The front faces of the sections abut one another and have respective recesses. The thickness of the bar sections is reduced in recessed areas. A connecting fish plate, which can for example be constructed from a high strength material, is placed in the recesses. The blade sections, bar sections and fish plate are connected by cap screws and securing nuts. A blade section covers the butt joint between the two bar sections. The configuration enables absorption of inertial forces caused by the backwards and forwards reciprocating motion and compressive forces that result from the motion in the connection region.

Abstract: A gear arrangement (1) with a lubricant supply for driving agricultural equipment has a first gearbox (2) with a first casing portion (5) which limits a first interior space (6).

A connecting channel (27) connects the two gearboxes (2, 3) so that lubricant in the first interior space (6) flows into the second interior space (8). The gear arrangement (1) further includes a connection mechanism (33) to supply lubricant to the two gearboxes (2, 3). The connecting channel (27) is arranged such that the lubricant in the first gearbox (2) flows through the connecting channel (27) into the second gearbox (3) when the lubricant exceeds a minimum filling level (30). An air-venting unit (34) in the form of a channel is provided in the first gearbox (2).

Abstract: A control for a structural assembly oscillatingly supported around a swivel axis on a base unit in a harvesting machine and including a cutter table inclinably supported about an axis of rotation relative to a conveyor channel, has an hydraulic operation cylinder. The inclination of the cutter table relative to the conveyor channel is effected by the hydraulic operation cylinder pivoted at one end to the conveyor channel and at the other to the cutter table. An hydraulically loaded relief cylinder, the pressure medium of which is cushioned by a pressure reservoir, is installed with one end to the conveyor channel and with the other end to the cutter table so as to balance a position of the cutter table relative to its point of rotation by the force of the relief cylinder.

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.
