Abstract:
1. An arrangement for coupling an implement attachment to a working arm of a working machine, comprising: an implement attachment having two side-plates which each carry two bushings having openings defined therein for receiving fastener pins; the side-plates have a circular hole defined therein, the bushings being adapted to fit in the circular hole; the bushings being secured to the side-plates by a fastener element; each bushing having a round guide portion, each round guide portion being rotatable within one of the circular holes of the side-plates, each guide portion having an opening defined therein for receiving one of the fastener pins; and the openings being eccentrically positioned in at least one of the bushings for each side-plate so that a rotational positioning of the bushings is selectable to align the eccentric openings of the bushings with a position of the fastener pins prior to securing the bushings with the fastener element wherein each fastener pin is locked to the round guide portion by a second fastener element that is screwed into a screw-threaded hole in the round guide portion.
