An agricultural implement apparatus includes a center section and wings pivotally attached to ends of the center section. Wing wheels are pivotally mounted to the wings about vertical axes. The wings can pivot from a transport position, where the wings extend rearward in alignment with the travel direction and where a rotational plane of each wing wheel is aligned with the corresponding wing, to a field position where the wings extend perpendicular from the center section and where the rotational plane of each wing wheel is perpendicular to the wing. Right and left wheel actuators pivot the wing wheels from the transport position to the field position as the apparatus moves in the operating travel direction by pivoting the right wing wheel such that a front edge thereof moves to the right, and by pivoting the left wing wheel such that a front edge there moves to the left.
