摘要： An improved coupler assembly adapted for connecting a work implement to a prime mover. The main body portion of the coupler assembly has laterally spaced side plates, each of which includes first and second mounting-pin receiving slots having open mouths and apices. The mouths are adapted sequentially to receive first and second mounting pins secured to the work implement. The first slot is longer than the second slot, and the first slot incorporates a locating structure adapted to retain the first mounting pin within the mouths of the first slots before the second mounting pin is capable of being received within the mouths of the second slots. A locking sub-assembly having a rotator member extends laterally between the apices of the first slots. The rotator is mounted for rotation between a first and a second position. The rotator is adapted to engage the first mounting pin, when the rotator is in its first position, to retain the first mounting pin within the apices of the first slots. The rotator is also adapted, when in its second position, selectively to permit the first mounting pin to slide along the first slots after the second mounting pin is in substantial vertical alignment above the second slots.
