<p>The invention relates to an arrangement for coupling an implement attachment (30) to a working arm (10) of a working machine, wherein the arm (10) is connected to the implement attachment (30) through the medium of fastener sleeves (11, 14) and fastener pins (16, 17). The attachment (30) includes two side-plates (32, 33) which each carry two bushes (44-47) that include holes (56) for accommodating the fastener pins (16, 17). The bushes (44-47) have a circular guide portion (52) which fits into a circular hole (34-37) in respective side-plates (32, 33). The bushes (44-47) include a respective flange (50) which is connected to the side-plates (32, 33) by means of a fastener element (70). The hole (56) receiving respective fastener pins (16, 17) is positioned excentrically in relation to the guide portion (52) in respect of at least two of the bushes (45-47). The invention enables the implement attachment to be adapted readily to mutually different working arms.</p> |
