The tooth has a bent grubber shaft (1) loaded by a spring (3). The grubber shaft is pivotably arranged on a support (10) of a grubber by a holder (4), and includes a share blade (12) at a lower end. The grubber shaft is pivotable around a transverse axle (2) attached to the holder, where the transverse axle is arranged above the support and in a pulling direction of the grubber before a tip (21) of the share blade. The spring is designed as a leaf spring arranged between the holder and a guide (17). The guide includes two side parts (18), which are spaced at a distance from each other. |
