    摘要： A chopper blade for use in an agricultural harvester chopper to chop crop residue comprises a blade body and a hard face. The blade body comprises a cutting edge of the chopper blade. The hard face is applied on a surface of the blade body, and is harder than the blade body. The hard face comprises a serration pattern along a cutting edge such that the cutting edge wears to the serration pattern to match the serration pattern to form corresponding serrations in the cutting edge with the serration pattern becoming part of the cutting edge of the chopper blade during use of the chopper blade.

    摘要： A chopping blade for cutting against a shear bar has a main body made of hardened steel. The blade body is formed with at least one cutting-edge region, a fastening region for fastening the blade to a carrier and in each case a transition region between the cutting-edge region and the fastening region. The main body bears a hard material coating in the cutting-edge region. The hardness of the main body is uniform throughout over all regions. A chopping drum carries a multiplicity of these chopping blades on its periphery and, upon rotation of the chopping drum, the chopping blades cut material upon running up against a stationary shear bar.

    摘要： In a forage harvester which has an automatically adjustable shearbar mechanism for adjusting the distance between the shearbar and a rotating cutterhead, rotation of the cutterhead is determined by the use of essentially steady state signals without substantial transient components.

    摘要： An apparatus comprising a pair of associated chopper drums, including a top chopper drum and a lower chopper drum. The chopper drum defines an axial cylindrical bore having a rotational axis into which is mounted a drive shaft (not shown) that is keyed radially to drive the chopper drum. Radially spaced from the rotational axis are a plurality of outwardly facing recesses defined by walls of a body of the chopper drum. Each recess extends longitudinally along the periphery of the chopper drum end-end to provide a recess for mounting a corresponding plurality of cutting blades. Each recess is defined by a longitudinally extending lower wall and an opposed and circumferentially spaced. The cross sectional profile of the chopper drum is generally consistent throughout its length and includes a plurality of ridges and troughs with the ridges built up to define therein the recesses, the ridges being interposed by the troughs. A higher side wall provides support for the cutting blade and is inclined relative to a plane extending radially outwardly from the rotational axis. The opposed smaller side wall supports a wedge clamp.

    摘要： A crop processing and/or conveying element for a forage chopper has a body that can be mounted on a carrier that can be set in rotation and is furnished with a hard material layer that comes into contact with crop during operation. The hard material layer is connected in a form-fitting manner to the body.
