Abstract
A hybrid male coupler portion for a front-end loader mates selectively and interchangeably with first and second different female coupler portions. The coupler portion includes a frame. The frame includes: (i) first and second arm pin-on locations adapted for connection to associated first and second arms, respectively; (ii) at least one tilt member pin-on location adapted for connection to an associated tilt member; and (iii) first and second coupler halves. Each of the first and second coupler halves includes: a first hook-engaging mount; a first rib locking location aligned with the first hook-engaging mount; a second hook-engaging mount; a second rib locking location aligned with the second hook-engaging mount; and, a plunger pin slidably connected to the frame and movable between an extended position and a retracted position. The plunger pin, when extended, is adapted to engage and retain an associated female coupler portion rib ear located in one of the first and second rib locking locations.
