Abstract: Cutting blades and counterblades are presented having long edge life for chopping devices equipped with blades mounted on rotating drums and with counterblades which fit into the gaps between the blades, the blades and/or counterblades being produced by rolling at least one of the longitudinal edges of a piece of flat strip material to form a slightly rounded, prismatic cutting edge, the rolling being continued until satisfactory sharpness is obtained.

Abstract: A double-knot twine-knotter unit with twine tying having a plurality of double-knot twine knotters combined on one knotter drive shaft. Each double-knot twine knotter comprises at least one knotter drive disc, a knotter chassis, a knotter assembly and a blade lever. The knotter drive disc is fastened fixedly on the knotter drive shaft which can be driven about its axis. The knotter chassis carries a knotter assembly, which forms two knots following one another, and the blade lever which is driven by a cam track of the knotter drive disc. The knotter assembly is arranged so as to overlap in the axial direction of the knotter drive shaft with the knotter drive disc of the adjacent double-knot twine knotter on a part length of the knotter assembly.

Abstract: A twine knotter (10) for bale compactors comprises a knotting frame (11) with a knotting hook (9), supported rotatably on a knotting hook shaft (40), which forms a swivel pin in the knotting frame (11); with a hook part (41), projecting laterally from the knotting hook shaft (40), which hook part has a continuous through-opening (52) with an approximately rectangular cross section, this opening extending in the plane formed by the knotting hook shaft (40) and the hook part (41), the side boundaries of the opening being formed by cheeks (63, 64). A knotting tongue (44) is supported on the knotting hook (9) with freedom to pivot around a pivot pin (43), which is perpendicular to the plane formed by the knotting hook shaft (40) and the hook part (41) and which passes transversely through cooperating bores (65, 66, 67) in the cheeks (63, 64) and the knotting tongue (44).

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 second gearbox (3) with a second casing portion (7), which limits a second interior space (8) is connected with said first gearbox (2). 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).
