ABSTRACT:
A tool bar having a hollow central section and oppositely extending offset hinged wings movable from a generally horizontal, transversely extending working position to a folded transport position. A hydraulic cylinder is positioned in the central section adjacent each wing and has its rod end pivotally connected to a pair of sliders below their center position for an effective lever action about the offset hinge with the sliders substantially spanning the hollow central section. The rod end is also pivotally connected to a pair of links via a slotted connection, with the links also being pivotally connected to the ear of a wing. The sliders reduce wing fall as the cylinder moves the wing from the working position approximately 180.degree. to a transport position on top of the central section or vice versa. The slotted link connection prevents binding of the sliders against the central section during the procedures.
