Abstract

A tool bar having a hollow central section and oppositely extending offset hinged wings movable from a generally horizontally 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 pivotally connected to a pair of rollers substantially spanning the hollow central section and to a pair of links via a slotted connection, with the links also being pivotally connected to the ear of a wing. The rollers reduce wing fall as the wing moves 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 rollers against the central section during the procedures.
