Abstract: A loader coupler includes left and right inner rib mounts that mate with left and right ribs of a first type of attachment coupling structure. The coupler also includes left and right outer rib mounts that mate with left and right ribs of a second type of attachment coupling structure. Left and right plunger assemblies each move between a locked and unlocked position and each includes both a first lock plunger and a second lock plunger. The left and right first lock plungers extend into left and right inner locking regions when the left and right plunger assemblies are located in the locked position. The left and right second lock plungers extend into left and right outer locking regions when the left and right plunger assemblies are located in the locked position.

Abstract: A loader coupler includes a body with 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 are provided on the body and are adapted to mate respectively with left and right ribs of a first type of attachment coupling structure. Left and right inner locking regions are defined by the body and are vertically aligned with the left and right inner rib mounts, respectively. Left and right laterally spaced-apart outer rib mounts are provided on the body and are adapted to mate respectively with left and right ribs of a second type of attachment coupling structure. Left and right outer locking regions are defined by the body and are vertically aligned with the left and right outer rib mounts, respectively. A lock system includes left and right plunger assemblies that each move between a locked and unlocked position.
