Implement coupling device and a machine provided with such a device

Implement coupling device on a working machine;

• the device comprising
• a coupling means provided with a first shaft;
• an engagement means provided with a second shaft arranged parallel to the first shaft;
• at least one linkage comprising a first portion connected to the first shaft and a second portion connected to the second shaft, which first and second portions are connected by a pivot joint;
• and
• a wedge means arranged to be removably mounted between the first and second portions which wedge means is fixed in position to prevent relative movement of the first and second portions when an implement is attached to the coupling device;
• wherein the coupling means and the engagement means are displaceable relative to each other in a direction at right angles to the first and second shaft axes to attach or release the implement;
• wherein at least one of the first and second portions making up the linkage is detachably fixable to its respective shaft by a locking means receivable in a longitudinal recess at right angles to the shaft axis and engagable with a tangential recess in the outer surface of the shaft;
• and the locking means provides a datum point determining an axial projection of the shaft relative to the linkage portion.
