Abstract

The automatic coupling incorporates an attachment frame (13) coupled to the hydraulic lifting devices (5) of a tractor, and to a jack (13). On the bottom of the frame (13) are jaws each with a housing in which is inserted a bar (66) fixed onto the fixed frame of the implement. On the jaws (15) is a locking hook (64) hinged on a shaft (65) and gripping the bar (66) in the recess of the jaws. A spiral screw (67) is fixed on one side onto a rod (68) forming part of the frame (63), and on the other side onto a pin forming part of a bar hinged on an axle (71) positioned as an extension of the hook (64). A rod (73) joined to a lever (74) is hinged on an axle.
