In a toolholder for mowers and choppers, there is a rotating tool carrier, to which the tools (1) are fastened pivotably about bolts (4) parallel to the axis of rotation of the tool carrier. The bolts (4) carrying at least one tool (1) are mounted at their ends in long holes (3), directed radially to the axis of rotation, of two mutually opposite tabs (2) fastened to the tool carrier and projecting approximately radially from this or of discs (2a) forming the tool carrier itself and are secured against axial displacement in the radially outer portion of the long holes (3). In order to achieve a secure bolt retention even with thin tabs (2) or discs (2a) and a short bolt, the two mutually opposite long holes (3) possess respectively projections (5) provided in the radially outer portion on their sides facing the other long hole and located on the long-hole side walls and the bolts (4) are provided with corresponding contractions (4b). …<IMAGE>… |
