Abstract:
An agricultural implement includes a hitch boom to which a pair of wing booms is pivotably connected. The wing booms are designed to fold forward from an extended position to a transport position. The wing booms are supported above a surface by wheels that provide the aforementioned support when the wing booms are in an extended position as well as the transport position. Maintaining surface contact of the wheels in both positions reduces the load placed on the hitch to which the hitch boom is coupled as well as the hitch boom itself. Multi-link draft links are connected between the hitch boom and the wing booms to provide support for the wing booms when the wing booms are in the extended position. The relative length of the draft links dictates how far the hitch telescopes when the wing booms are folded to the stowed or transport position.
