摘要： A cultivator for an agricultural soil processing machine, which includes a base part which has a cutting element on a cutter support. The base part has at least one screw receiving area for securing to a support, in particular a tine of the agricultural soil processing machine. The screw receiving area is designed as a blind hole with an inner thread and is recessed into a cultivator support surface aligned opposite the tool advancing direction of the cultivator, or the screw receiving area is designed as a through-bore with an inner thread and is covered by at least one wear protection element in the tool advancing direction.

摘要： The invention relates to a shear bar (20), in particular for a forage harvester or another agricultural or silvicultural machine, having a carrier (21) that comprises a cutting region (30); a plurality of cutting elements (31) being set alongside one another in the cutting region (30); the cutting elements (31) comprising a partial edge and at least some of the partial edges forming a cutting edge (32) that is embodied to form, with a knife bar, a cutting engagement for the material to be shredded; the cutting edge (32) forming a transition between a cutting surface (32.1) that is constituted by the cutting elements (31) and extends transversely to the cutting direction, and an exposed surface (32.2) that extends substantially in a cutting direction and indirectly or directly adjoins the cutting edge (32). A shear bar of this kind can be configured to be break-resistant with little complexity in terms of parts and manufacture if provision is made that an infeed element (34), which is embodied as a sintered part made of hard material having an infeed bevel (34.6) profiled on in the sintering process, is provided on or in the row of cutting elements (31); the infeed bevel (34.6) being carried over indirectly or directly into the cutting edge (32); and the infeed bevel (34.6) being arranged at a tilt with respect to the cutting edge (32) in such a way that it is arranged with a setback with respect to the exposed surface (32.2) and toward the cutting surface (32.1).
