    摘要： The invention relates to a beet puller share having a base part which comprises a cutting edge, wherein one or several hard material elements which form deflecting faces on their top surfaces are arranged in the region of the cutting edge, wherein the deflecting faces transition into a surface region of the base part, and wherein the surface region forms a beet guiding zone, in particular, a beet ejecting zone. To improve the service life of the beet puller share and to improve the harvest yield connected therewith, it is provided according to the invention that the hard material elements are realized as cutting elements which form the cutting edge at least in regions and that the deflecting face of at least one cutting element is convexly curved and merges into the convexly curved beet guiding zone, in particular, beet ejecting zone.
