摘要： A concave section for a harvester includes a concave body having an upstream side, a downstream side, a leading end and a trailing end. The concave body defines an arcuate crop engagement face facing radially inwardly. A plurality of crop passage openings are defined through the arcuate crop engagement face. A cover is configured to at least partially cover at least some of the crop passage openings. The cover is carried by the concave body and is movable thereon between at least two different positions to adjust a degree of openness of at least some of the crop passage openings.

摘要： An agricultural cutting blade has top and bottom surfaces and mounting apertures extending through top and bottom surfaces. A cutting edge support surface (e.g. that may be a flat, pointed or rounded) is formed on the cutting blade body with the cutting edge support extending along a side of the cutting blade body transversely between the top and bottom surfaces. A clad material deposited upon the cutting edge support such as by laser cladding process. The clad material can be built up, that is layered in partial or full overlapping relation to provide at least 2 and often more than 4 layers of clad material at one or more locations. A cutting edge provided by the clad material that may be a ground surface into a laser clad bead.

摘要： A sickle bar assembly employs a plurality of laminated strips that are secured and that may be stacked vertically upon each other in abutting relation to form a sickle bar. The individual sickle sections are secured to the sickle bar in side-by-side relation. Laminated stacks may also be joined to each other by way of a splice joint to provide for even longer bar. The strips may be heat treated strips of steel as opposed to cold rolled steel or other high strength strip material.

摘要： A modular sickle bar having a knifeback for use in a crop harvesting header having a plurality of cutting sections fastened together and to a knifeback. The sections are locked together with use of a locking system which restrains relative movement of the joined sections along planes parallel to and perpendicular to the longitudinal axis of the knifeback when the crop harvesting header is in use.
