An attachment system for an implement (l) f which is arranged to be connected, at least in a working position, to a three-point implement linkage (21) on an implement carrier (2) and is provided with at least one wheel (15), which is arranged to support the implement (1) in the transport position (T), characterized by connection pins (128) which are arranged to be connected to the lower three- point connectors (211a, 211b) of a three-point implement linkage (21) are arranged to be adjustable between a retracted working position (W) and a transport position (T) displaced in a direction away from an implement frame (11). The system allows for an easy transition between a working position where the 3 point connector is used, and a transport position where the implement can be easily transported
