Abstract

A hinge connection for a wheel supporting, segmented cross shaft of a winged implement permits the wing to be folded to a transport position in any raised or lowered position of the implement. The hinge connection includes a pin carried by a laterally outer end of the main frame segment of the cross shaft which cooperates with a pair of slots in legs extending from the adjacent end of a wing frame segment of the cross shaft.
