Abstract

A device for the automatic coupling of agricultural machines to tractors, comprises two members attached one to each of the power lift arms, and a third member attachable to the top link. An agricultural machine is coupled to the two members by raising the lift arms, and to the top link by reversing the tractor. Each of the two members comprises a pair of plates linked by a brace and provided with a clamping piece. The end of a power lift arm is inserted between the plates, brace and clamping piece, and secured by a pin through a hole. The coupling bar of the machine is guided by chamfers into a slot where it is retained by a catch which may be pivoted or sliding, and spring-loaded.
