ABSTRACT:
An attachment for tractors to permit connection with trailer couplings has a pair of plates, the outer of which carries a latch provided with a spring-loaded latching pin for releasable joinder with the couplings. The outer plate is reciprocated toward and away from the tractor by the piston shaft of a hydraulic cylinder, and a pair of rods guide the outer plate during reciprocation. After latching of the pin to the coupling the shaft is withdrawn to place the plates next adjacent each other, and before movement of the two vehicles, the plates are interconnected by a spring-loaded locking bolt carried by the inner plate.
