A male coupler portion includes a frame having a front region and a rear region that is pinned to the machine. A first pair of hook engaging mounts are adapted to be received respectively by first and second hooks of a female coupler portion; a first pair of openings are adapted to receive first and second ears of a female coupler portion; first and second lock members are movable between an unlocked position and a locked position to engage the ears of the female coupler portion.
