Claim:
A loader coupler comprising: a body comprising a front region, a rear region, an upper region, a lower region, and left and right lateral sides, a tilt actuator pin-on location, and left and right arm pin-on locations; left and right laterally spaced-apart inner rib mounts provided on the body and adapted to mate respectively with left and right ribs of a first type of attachment receiver structure; left and right inner locking regions defined by the body and vertically aligned with the left and right inner rib mounts, respectively; left and right laterally spaced-apart outer rib mounts provided on the body and adapted to mate respectively with left and right ribs of a second type of attachment receiver structure; left and right outer locking regions defined by the body and vertically aligned with the left and right outer rib mounts, respectively; a lock system connected to said body, said lock system comprising: a first actuator comprising both left and right first lock plungers that each move in response to fluid pressure in said first actuator between locked and unlocked positions along a first plunger axis; a second actuator comprising both left and right second lock plungers that each move in response to fluid pressure in said second actuator between locked and unlocked positions along a second plunger axis that is parallel and spaced-apart from said first plunger axis; wherein: said left and right first lock plungers extend into said left and right inner locking regions when located in their locked positions; said left and right first lock plungers are at least partially withdrawn from said left and right inner locking regions when located in their unlocked positions; said left and right second lock plungers extend into said left and right outer locking regions when located in their locked positions; and, said left and right second lock plungers are at least partially withdrawn from said left and right outer locking regions when located in their unlocked positions.
