A tow ball adaptor for coupling an implement hitch to a tow ball includes a plate. A first hole in the plate is complementary to and configured to insert a tow ball that is coupled to a vehicle. A coupler is coupled to the plate and configured to couple to the tow ball to retain the tow ball in the first hole. A cutout that extends into the plate is substantially complementary to and configured to insert an implement hitch. A plurality of third holes in the plate extends linearly between the first hole and the cutout. The third holes are complementary to and positioned to selectively align with a pair of orifices that is positioned singly in an upper and a lower tongue of the implement hitch. A hitch pin is inserted through the orifices and the third hole to couple the implement hitch to the plate.
