Abstract (en)
A tool 1 is coupled to a work machine 3 by an assembly comprising a tool mounting body 110 connected to the tool 1 and a machine mounting body 130 connected to the work machine 3. The machine mounting body 130 comprises one or more first connectors 33, 34 which releasably engage the tool mounting body in a mounted position relative to the machine mounting body, and one or more second connectors 50. Each second connector is movable relative to the machine mounting body in a first stage of movement in a first direction D1 from a release position to an engaged position, in which the tool mounting body 110 may be retained in the mounted position on the machine mounting body 130, and then in a second stage of movement in a second, different direction D2 from the engaged position to a lock position in which the tool mounting body 110 is locked in the mounted position in fixed relation to the machine mounting body 130 to transfer forces between the work machine 3 and the tool 1.
