An adapter frame for installation of a front and an accessory implement, such as a snowplow blade and a sidewing, on a vehicle having a coupling plate is disclosed. The adapter frame has a frame structure. The adapter frame also comprises a hitch coupling mechanism for removably coupling the adapter frame to the vehicle coupling plate. The adapter frame further comprises a front implement coupling receptacle mechanism for removably receiving a corresponding coupling mechanism arranged on a front implement support frame attached to a rear portion of the front implement, the front implement support frame coupling mechanism being adapted to be removably coupled to the vehicle coupling plate. The adapter frame also comprises an accessory implement coupling mechanism for removably coupling the adapter frame to the accessory implement. The adapter frame increases the implement reconfiguration capability of the vehicle. A method for installing the adapter frame is also disclosed.
