Claim:
1. A loader coupler adapted to mate alternatively with both first and second associated attachment receiver structures, said loader coupler comprising: a one-piece cast steel body comprising left and right portions and upper and lower regions; left and right laterally spaced-apart outer rib mounts comprising respective outer mount pins connected to said body, said left and right outer rib mounts adapted to releasably mate respectively with left and right open hook portions of the second associated attachment receiver structure; left and right outer locking regions defined by said one-piece body and aligned respectively with the left and right outer rib mounts, said left and right outer locking regions adapted to receive left and right ear portions of the second associated attachment receiver structure, wherein: left and right laterally spaced-apart inner rib mounts connected to said body, said left and right inner rib mounts adapted to releasably mate respectively with left and right open hook portions of the first associated attachment receiver structure, wherein each of said left and right inner rib mounts comprise respective left and right inner mount pins each comprising: a pin body including a first end and a second end; and, a base plate connected to said first end; said pin body of said left inner mount pin extending between said second and third ribs of said left portion of said body, and said base plate of said left inner mount pin abutted with said third rib of said left portion of said body; said pin body of said right inner mount pin extending between said second and third ribs of said right portion of said body, and said base plate of said right inner mount pin abutted with said third rib of said right portion of said body; left and right inner locking regions defined by said one-piece body and aligned respectively with the left and right inner rib mounts, said left and right inner locking regions adapted to receive left and right ear portions of the first associated attachment receiver structure, wherein: a lock system connected to said one-piece body, said lock system comprising: (i) left and right first lock plungers that move between locked and unlocked positions relative to said left and right inner locking regions, respectively; and, (ii) left and right second lock plungers that move between locked and unlocked positions relative to said left and right outer locking regions, respectively, wherein: the respective mount pins of said left and right outer rib mounts removably connected to said one-piece cast steel body, each of said left and right outer mount pins comprising a pin body including a first end, a second end, and a base plate connected to said first end, wherein: said pin body of said left outer mount pin extends between the first and second ribs of said left portion of said body, and said base plate of said left outer mount pin is fixedly secured to one of said first and second ribs of said left portion of said body by at least one removable fastener; and, said pin body of said right outer mount pin extends between the first and second ribs of said right portion of said body, and said base plate of said right outer mount pin is fixedly secured to one of said first and second ribs of said right portion of said body by at least one removable fastener; said one-piece body further comprising a rear side including a left arm pin-on location adapted for pivoting connection of a left associated loader arm, a right arm pin-on location adapted for pivoting connection of a right associated loader arm, and a tilt actuator pin-on location located between the left and right arm pin-on locations and adapted for pivoting connection to an associated tilt actuators; wherein: said second rib on both said left and right portions of said coupler body includes a pin retaining aperture extending there through, and said second rib on both said left and right portions of said coupler body includes a pin locating stud that projects from said second rib toward said third rib; said second end of said left inner mount pin includes a recess that receives said pin locating stud on said left portion of said coupler body; said second end of said right inner mount pin includes a recess that receives said pin locating stud on said right portion of said coupler body; said coupler further comprising: (i) a left pin retaining fastener that extends through said pin retaining aperture on said left portion of said coupler body and that is threadably engaged with said left inner mount pin; and, (ii) a right pin retaining fastener that extends through said pin retaining aperture on said right portion of said coupler body and that is threadably engaged with said right inner mount pin; said pin retaining aperture on said left portion of said coupler body and said left pin retaining fastener extends through said pin locating stud on said left portion of said coupler body; and, said pin retaining aperture on said right portion of said coupler body and said right pin retaining fastener extends through said pin locating stud on said right portion of said coupler body.
