ABSTRACT:
An automatic hitch with safety lock may be mounted on a tractor or the like and has two laterally opposed jaws and a hook member pivotally connected therebetween and provides completely automatic latching and unlatching to an upstanding pin provided on a wagon or trailer. The latch has a combination release and spring operator for remotely retracting the hook member and unlatching the pin from the hitch. A safety lock has a lock shaft which rides a shoulder on the hook member and prevents the hook member from being retracted to an open position until the lock shaft is retracted from a position adjacent the shoulder. The safety lock may be remotely operated and has a spring biasing it into the locked position. A manual lock pin may be inserted to effectively disable the automatic operation of the hitch. A mounting plate is used to attach the hitch to a tractor or other vehicle and shock absorber springs are provided between the hitch portion and the mounting plate.
