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.

Cultivator which is screwed on the rear face

A soil-working system for an agricultural soil-working machine, comprising a base element, which is designed to hold a bottom element, wherein the bottom element has at least one cutting element, and comprising an injection element for introducing substances into the soil material to be worked, wherein the soil-working elements are detachably or undetachably connected to a carrier element of the soil-working machine, wherein the detachable connections form an interlocking and/or frictional connection and wherein the elements at least partially form a protection against abrasive wear in relation to each other.

Soil-working system

Soil working tool for an agricultural machine, in particular a cultivator, which is fixed on a tool holder and has a tine-like region to which a preferably guide plate-like element is attached. In order to achieve an improved soil flow across the soil working tool with good wear protection and thus a sufficient service life of the soil working tool, the tine-like region has two side strips which run in the longitudinal direction of the soil working tool and have notch-like recesses extending in the transverse direction, and that an at least approximately smooth center strip region is located between the two side strips in the center in the longitudinal direction of the tine-like region of the soil working tool.

Soil working tool

The present invention relates to a tool system for an agricultural ground cultivating machine having a base part which communicates, by means of a releasable connection, with a carrier element, in particular with a tine of the agricultural ground cultivating machine, wherein the base part comprises a cutter and, adjoining the cutter, at least one hard material element, and wherein the carrier element comprises, in its end region pointing in the operating direction, laterally arranged wing shares which are fitted with hard metal plates. In this case, it is provided that the edge of the wing share which is fitted with hard metal plates runs up to a lateral surface of the carrier element. The present invention additionally relates to an associated wing coulter. The tool system has reduced wear and tear and consequently extended changing intervals.
