摘要： A protection element for an earth-working implement includes a flat plate having a wearing portion on a side of the flat plate facing a distal end of the earth-working implement. A lower portion of the flat plate forms an attachment portion provided with notches, projecting portions, or a combination thereof configured to engage with the earth-working implement. When the attachment portion is engaged with the earth-working implement, the protection element is configured to project above a plane coinciding with a top surface of at least a portion of the earth-working implement proximal to the protection element such that the portion of the earth-working implement proximal to the protection element is shielded from a flow of loose mass during use of the earth-working implement. The wearing portion is arranged at an upper portion of the flat plate. The attachment portion is arranged at a lower portion of the flat plate.

摘要： A wearing-part arrangement for a leading edge of a soil-working implement includes a point configured to be releasably attached to the soil-working implement. The point has a pointed front portion and a transverse elevation projecting from an upper face thereof. At least the front portion is mirror-symmetrical around a longitudinal axis of the point and has first and second oblique faces diverging in a direction of a socket on the point and merging with a first side edge surface and a second side edge surface. The first oblique face is bounded by a first cutting edge, and the second oblique face is bounded by a second cutting edge. When the point is attached to the soil-working implement, at least a rear portion of the second oblique face and the second side edge surface adjacent to the second oblique face project beyond a side edge of the soil-working implement.

摘要： A device for automatically adjusting the working width of the first plough body of a plough in accordance with the variable working width of subsequent plough bodies. A first hydraulic cylinder displaces a rear frame section laterally. A second hydraulic cylinder pivots the rear frame section to adjust a transverse spacing of the plough bodies. The first hydraulic cylinder includes a multi-stage cylinder. A first cylinder stage forms a main lateral control, and a second cylinder stage forms an automatic working-width control for the first plough body. The second cylinder stage is in hydraulic-fluid communication with the second hydraulic cylinder in a master-slave configuration. The second cylinder stage is master or the slave depending on a moving direction of the cylinder stage and the second hydraulic cylinder being slave or the master. Piston diameters are matched to provide a correction of a lateral displacement of the front frame section.

摘要： An assembly for attaching a replaceable wearing part to a leading edge of an implement includes a wearing-part holder configured to be received and fixed to a supporting surface formed at the leading edge of the implement and a replaceable wearing part. One of the wearing-part holder and the wearing part forms an attachment projection and the other of the wearing-part holder and the wearing part forms a corresponding socket. The attachment projection and the socket are provided with corresponding, cooperating guide portions. The guide portions of the wearing-part holder are formed as guide faces racing the supporting surface and being slanted relative to the supporting surfaces in a direction falling when moving away from the leading edge.
