Patent ID: 7954262

Claim:
An adapter frame for installation of a front implement and an accessory implement on a vehicle having a coupling plate, the adapter frame comprising: a frame structure; a hitch coupling mechanism attached to the frame structure for removably coupling the adapter frame to the vehicle coupling plate; a front implement coupling receptacle mechanism attached to the frame structure and receiving a corresponding coupling mechanism arranged on a front implement support frame attached to a rear portion of the front implement, said front implement support frame coupling mechanism being adapted to be removably coupled to the vehicle coupling plate; and an accessory implement coupling mechanism attached to the frame structure for removably coupling the adapter frame to the accessory implement, wherein the hitch coupling mechanism and the front implement support frame coupling mechanism are matingly interfittable on the vehicle coupling plate, the hitch coupling mechanism comprises a pair of wedging engagement members shaped to be vertically inserted into corresponding apertures of receptacle structures on the vehicle coupling plate, and the front implement coupling receptacle mechanism comprises a pair of adapter receptacle structures with apertures that are shaped to vertically receive corresponding wedging engagement members on the front implement support structure.
