Abstract
A farm implement supported by at least one wheeled support mounted on a pivot arm extending from a wing and at least one tracked support on a main carrier. The tracked support can be rotated about a primary rotational axis and the wheeled support being rotatable about a secondary rotational axis. The pivot arm can be rotated to position the wheeled support to elevate or lower the wing. The rotational of the pivot arm also changes the alignment of the secondary rotational axis of the winged support relative to the primary rotational axis of the tracked support to prevent berming when maneuvering the farm implement.
