Abstract: A quick coupler for coupling an implement to a work machine is provided with a control system that substantially prevents inadvertent and unintended release of the implement from the machine. Inadvertent and unintended release of the implement is prevented by requiring two separate switches to be actuated to release the implement. Actuation of one switch supplies pressurized fluid to a fluid circuit connected to an actuator operable to release the implement from the machine. However, the pressurized fluid supplied in response to actuation of the one switch is not sufficient to activate the actuator. Concurrent actuation of a second switch raises the pressure of the fluid supplied to the actuator fluid circuit to a level sufficient to activate the actuator, thus releasing the implement.
