Abstract
An agricultural implement apparatus comprises a center section, inner foldable wings, outer foldable wings, and foldable wing extensions oriented substantially horizontally when in the field position. When in the transport position, the center section is horizontal, the inner wings extend vertically from ends of the center section, the outer wings extend downward and inward from upper ends of the inner wings such that lower ends of the outer wings are adjacent to each other, and the wing extensions extend downward and outward from the lower ends of the outer wings toward corresponding ends of the center section. A wing locking and folding apparatus includes an over-centering locking mechanism, and maintains an implement wing extension in alignment with an implement wing when in a field position, and folds the wing extension upward to a transport position.
