The quick hitch coupler seeks to solve the problem of holding work attachments securely to the dipper arm of an excavator, while still allowing quick change of work attachments. The present invention also seeks to solve this problem in the simplest way possible. The coupler firstly uses a spring or other biasing means to keep the two jaws of the coupler held apart to secure the two pins of a work attachment, and it uses a hydraulic lock in conjunction with a hydraulic actuator to also hold the two jaws of the coupler held apart. But in addition to these two safety features, the coupler also uses a latch on the forward jaw which is controlled by movement of a slide which forms a part of a second or aft jaw of the actuator. The latch itself is includes a locking feature to prevent inadvertent release of the latch.
