An improved frame for a drawn agricultural implement, such as a planter, includes a telescoping main frame. The main wheel set is mounted to a sliding carriage to support the central main frame, and may be moved between a forward and a rear position. As the main frame extends, the wing sections fold forwardly. When the wing sections in the illustrated embodiment are completely folded, hydraulic cylinders slide the main wheel set forwardly so that the down load on the hitch is reduced for road transport. Conversely, during the unfold cycle, the hydraulic cylinders return the wheel set to the rear position, and the wings are then extended (i.e., unfolded) for field use.
