Abstract
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 ().
