Patent ID: 7819202

Claim:
An agricultural implement apparatus comprising: a center section mounted on main wheels oriented to carry the center section in a forward operating travel direction; right and left wings pivotally attached to corresponding right and left ends of the center section about substantially vertical wing pivot axes; right and left wing wheels mounted at outer locations on the corresponding right and left wings operative to support the wings for travel in the operating travel direction; wherein the wing wheels arc pivotally mounted to the wings about substantially vertical right and left wheel axes; wherein the wings can pivot from a transport position, where the wings extend rearward from ends of the center section and are oriented substantially in alignment with the operating travel direction and where a rotational plane of each wing wheel is substantially aligned with the corresponding wing section and with the operating travel direction, to a field position where the wings extend substantially perpendicular from ends of the center section and where the rotational plane of each wing wheel is substantially perpendicular to the wing and aligned with the operating travel direction; a right wheel actuator operative to pivot the right wing wheel from the transport position to the field position as the apparatus moves in the operating travel direction by pivoting the right wheel about the right wheel axis such that a front edge of the right wing wheel moves to the right; and a left wheel actuator operative to pivot the left wing wheel from the transport position to the field position as the apparatus moves in the operating travel direction by pivoting the left wing wheel about the left wheel axis such that a front edge of the left wing wheel moves to the left.
