Abstract

The invention refers to a fast coupling device of agricultural machines at tractors, especially in sowing. The fast coupling device of agricultural machines at tractors, according to this invention, consists of a male brace comprising a U-shaped frame (3) equipped with two position searching devices (7) that, during the movement of the tractor, position the sowing drill symmetrically by means of limiters (8) that touch the front surface (d) of some plates (9) on the female brace (B), after lifting the male brace (A) with the side rods (1), the bolts (4) with shift on the lower inclined surfaces (b and c) of the plates (9), thus opening a stop device (10) and then its closing and maintaining in this position by means of a hook (11) stressed as the stopping device (10) each by a spring (12), where the hook is solitary with a lever (13).<IMAGE>
