A robotic work tool system 200 comprising a robotic work tool 100, said robotic work tool 100 comprising a tool holder 160, e.g. in form of a disc, polygon, or comprising a plurality of arms, adapted to hold at least one tool 162 and adapted to be arranged in the robotic work tool 100, the tool holder 160 comprising at least one tool attachment means 164 and at least one spring attachment means 160a, 160b, 160c, wherein each tool attachment means 164 is positioned outside a respective spring attachment means 160a, 160b, 160c on a radius of the tool holder 160. The tool holder 160 is disc-shaped, polygon-shaped or comprises at least one rotating arm, and is equipped with two independent attachment means for each tool 162. By providing the tool holder with spring attachment means, plate springs could be attached to the tool holder as a further attachment means for the tools, which enables quick shifting of tools. To be published with FIG. 3.
