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.
摘要翻译：本发明涉及一种特别涉及具有拾取头和拾取轴的拾取头，其具有在其下侧具有定心凸耳的支撑元件，其中定心凸耳具有倾斜的倾斜面相对于拾取器的中心纵向轴线并且合并成座表面。为此，根据本发明的圆周通道设置在从中心面到座面的过渡区域中，并且通道相对于座面的深度大于或等于0.3mm。该选择具有优化的可旋转性，因此具有低磨损。

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.
