Patent ID: 8240970

Claim:
A loader coupling system comprising: an arm coupler and a link coupler each adapted to mate with an associated attachment, said arm coupler comprising: a body adapted to be connected to and extend between first and second spaced-apart arms of an associated loader machine, said body comprising first and second mounts located respectively adjacent the opposite first and second ends of the body, said first and second mounts comprising respective first and second convexly curved mount faces adapted to abut stop faces of respective first and second stop blocks of the associated attachment first and second plunger pins located respectfully at opposite first and second ends of said body; at least one plunger actuator operatively connected to the first and second plunger pins, said at least one plunger actuator selectively operative to move the first and second plunger pins between a retracted position and an extended position, said first and second plunger pins projecting outward from the respective first and second opposite end of the body a greater distance in the extended position as compared to the retracted position, wherein the first and second plunger pins are adapted to extend into apertures defined in first and second arm attachment ribs of the associated attachment, respectively, when the first and second plunger pins are located in the extended position; said link coupler comprising: a tilt link including a first end adapted to be pivotally connected to a control link of the associated loader machine and a second end including a hook adapted to selectively engage and retain a cross-pin of the associated attachment; a lock system connected to the tilt link and adapted to selectively capture the cross-pin of the associated attachment in the hook.
