A flat fold hinge assembly for implement frame sections that fold substantially greater than 90 degrees includes a modular hinge having first and second hinge portions that bolt solidly to the frame sections. A folding cylinder is protectively cradled between the sides of a cast mounting bracket closely adjacent the frame tube. Floating links are connected to the rod end of the cylinder generally below the main pivot which is offset above the frame tube a distance substantially less than most previously available hinge structures for compact storage of the wing frame close to the inner frame. The design, preferably utilizing four cast components, is more compact than previous designs so the frame sections fold more compactly. The simple mounting arrangement provides versatility in locating the hinge assembly to accommodate a wide variety implement configurations and implement attachments. The hinge structure acts to reinforce the tubular frame construction and distribute heavy loads transferred from implement attachments and tools. A mounting area on the hinge facilitates connection of additional hardware such as a wing support tube truss.
