Abstract: A quick coupler provides a way to securely lock implements to the coupler utilizing a design which receives hooks at connection locations and then directs pins into pockets at a rear of the implement. Instead of directing the pins along a pocket axis (as is done in the prior art), the pins are directed at an angle relative to the pocket axis thereby securely connecting the coupler to the implement. In fact some embodiments can have a pin extension system spaced from a wedge plate surface defining the pocket of the implement.

Abstract: A hybrid male coupler portion for a front-end loader mates selectively and interchangeably with first, second or third different female coupler portions. The coupler portion includes a frame having first and second arm pin-on locations adapted for connection to associated first and second arms, respectively; at least one tilt member pin-on location adapted for connection to an associated tilt member; and first and second coupler halves including first, second and third hook-engaging mounts, first, second and third rib locking locations aligned with the respective hook-engaging mounts, plunger pin(s) slidably connected to the frame, movable between locked and retracted positions possibly moving toward the center line of the frame when locked or in opposing directions.

Abstract: 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.
