Abstract: The invention relates to 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. The cultivator is characterized by reduced wear.

Abstract: The present invention relates to 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.

Abstract: The invention relates to a blade tip and to a tool combination having a blade tip for an agricultural soil cultivation machine, wherein the blade tip has a base part which has a cutter and a cutter carrier, and a guiding element attached to the blade tip, wherein the blade tip has a screw receptacle for fastening to a tine of the agricultural soil cultivation machine. Here, provision is made for the base part to have a receptacle which is covered by means of a covering portion in the tool feeding direction, for the guiding element to have a plug attachment which is held in the receptacle, and for a form-fitting connection, which prevents any movement of the guiding element out of the receptacle, to act in the region of the receptacle between the blade tip and the guide element.

Abstract: 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.

Abstract: 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.
