Abstract: A coupler assembly for coupling implements of the type having two connecting pins, to a vehicle. The coupler has a body component that is connectable to the vehicle, and the body component includes a forward recess for receiving a first connecting pin of an implement. The coupler also has a movable component which is supported by the body component and which is movable through a range of travel relative to the body component. The movable component includes, or forms a part of an aft recess for receiving a second connecting pin of the implement. An actuator selectively moves the movable component relative to the body component. A rear locking member is a part of the movable component and a rear lock actuator allows the rear locking member to be employed to prevent the second connecting pin from exiting the aft recess.
