摘要： 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.

摘要： The present invention relates to a shank chisel with a chisel head and a chisel shank, wherein the chisel shank has a securing element receptacle in which a securing element is arranged. In order to be able to make simple installation of the shank chisel in a chisel holder possible in a safe and maintenance-optimized manner of operation, it is provided according to the invention that a clamping element is adjustable relative to the chisel shank in such a manner that at least one part of the outer contour of the securing element is changed. The invention furthermore relates to a corresponding fixing assembly for a shank chisel in a chisel holder.

摘要： The invention relates to a tool system having a bit holder and a shank bit, the bit holder comprising a bit receptacle that comprises a first and a second diameter region that lead into one another via a transitional segment (taper), a bit shank of the shank bit comprising a first and a second cross-sectional region that lead into one another via a transitional segment. With a tool system of this kind, a wear-optimized design results from the fact that the transitional segments of the shank bit and of the bit holder are arranged spaced away from one another in the direction of the longitudinal center axis of the shank bit, in order to form a resetting space.

摘要： A round-shank pick having a pick head and a pick shank that includes a supporting element pierced along its longitudinal center axis by a mounting hole with an inside diameter for receiving the pick shank. A collar height, measured in the direction of the longitudinal center axis between an end, facing away from the seat surface, of the centering extension and the seat surface or between the end of the centering extension and an inner termination of a recess that is integrally formed in the supporting element in an indented manner with respect to the seat surface, is configured such that the ratio between the inside diameter of the mounting hole in the supporting element and the collar height is less than 8, and/or that the collar height is greater than an axial clearance of the pick mounted in a pick holder.

摘要： The present invention relates to a pick, in particular, a round shaft pick, having a pick head and a pick shaft, having a support element which has a centring lug on the underside thereof, wherein the centring lug has a centring surface which extends inclined with respect to the central longitudinal axis of the pick and merges into a seat surface. To this end circumferential channel according to the present invention is disposed in the transition region from the centring surface to the seat surface and the depth of the channel relative to the seat surface is greater than or equal to 0.3 mm. The pick has an optimised rotatability and thus a low wear.
