ABSTRACT:
A quick coupler for connecting and disconnecting an implement such as a bucket to and from a machine such as an excavator. In an example, the quick coupler includes a frame having recesses configured to receive pins located on the implement. The quick coupler includes first and second securing latches that are movable between latched and unlatched positions for removably latching the pins of the implement in the recesses. A rocker assembly and a connector link are provided for moving the second latch between latched and unlatched positions.
