摘要

The toothed system is provided for a tool for a ground working machine and involves a holder part (4) fitted to a tool, to which a toothed part is releasably arranged as an exchangeable or replaceable part in itself provided for ground working. The toothed part includes a rear shaft and a holder part with a hollow space (14), which when collaborating with the toothed part receives the shaft and provides a common connection (A,B) for accommodating loads. The loads are accommodated via a predetermined coupling geometry including special counterposed, mutually collaborating contact surfaces and at least release surfaces arranged on the toothed part and the holder part.
