The invention relates to a shear bar (), in particular for a forage harvester or another agricultural or silvicultural machine, having a carrier () that comprises a cutting region (); a plurality of cutting elements () being set alongside one another in the cutting region (); the cutting elements () comprising a partial edge and at least some of the partial edges forming a cutting edge () that is embodied to form, with a knife bar, a cutting engagement for the material to be shredded; the cutting edge () forming a transition between a cutting surface () that is constituted by the cutting elements () and extends transversely to the cutting direction, and an exposed surface () that extends substantially in a cutting direction and indirectly or directly adjoins the cutting edge (). 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 (), which is embodied as a sintered part made of hard material having an infeed bevel () profiled on in the sintering process, is provided on or in the row of cutting elements (); the infeed bevel () being carried over indirectly or directly into the cutting edge (); and the infeed bevel () being arranged at a tilt with respect to the cutting edge () in such a way that it is arranged with a setback with respect to the exposed surface () and toward the cutting surface ().

Shear bar

A blade tip, and a tool combination having a blade tip, for an agricultural soil cultivation machine. The blade tip has a base part including a cutter, a cutter carrier, a guiding element and a receptacle for fastening the blade tip to a tine of the agricultural soil cultivation machine. The base part has a receptacle covered by covering portion. The guiding element has a plug attachment held in the receptacle, and a form-fitting connection preventing movement of the guiding element out of the receptacle, provided between the blade tip and the guiding element.

Blade tip and tool combination having a blade tip

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.
