A tow frame for agricultural implements, such as seed drills, is provided. The tow frame includes a primary subframe for attaching to a tow vehicle and to an agricultural implement. A pair of wing subframes are hingedly mounted on opposite sides of the primary subframe. Second and third implements may be coupled to the wing subframes. The tow frame is foldable between a field configuration with the implements substantially transversely aligned and a transport configuration with the wing subframes folded rearwardly whereby the second and third implements are each positioned partly behind the first implement.
