Abstract: A mechanism for folding the wings of a multi-section implement from a transversely extending working position to a latched, vertical transport position relative to the main section and return. The mechanism includes a hydraulic cylinder that extends between the main section and each wing and a support and latch assembly. This assembly includes a fixed support on the main section and a telescoping tube for each wing which has its outer end pivotally connected to the wing and its inner end pivotally attached to the support. A latch structure is attached to the inner end of each tube and includes a crank arm pivotally mounted on the latch structure and pivotally connected to the rod of a single cylinder. A lever extends from this connection to a slidable mount on a slotted hole in the fixed support. The latch structure has a spring loaded tongue that engages a ramp having an aperture therefor on the outer end of each tube to latch the inner and outer ends of each of the tubes together.

Abstract: An implement that includes a central subframe, a center frame, a pair of wing frames pivotally connected to the ends of the center frame for movement between a transversely aligned operating position and a rearwardly folded transport position, and a set of extendable transport wheels mounted on the rear end of the subframe generally adjacent the wing transport wheels, wherein the noted transport wheels provide the sole ground contact of the implement during transport for desirable handling characteristics.
