A flexible folding agricultural implement includes a frame with a number of independent frame sections each supporting a plurality of ground working tools via front and rear ground engaging and depth adjustment wheels. Each frame section is attached to the adjacent section(s) via front flexible link connectors and rear ball joints. Each front flexible link connector is a bar pivotably attached at one end to the center point of one frame section, and, at the other end, to a front corner of an adjacent frame section in alignment with the respective rear ball joint and a scissor limit stop is positioned around each bar which scissor limit stops limit the amount of relative twist between adjacent frame sections to prevent roll over and to allow the link connectors to be made rigid such that they can act as pivot supports for the respective frame sections as they are folded for transport.

[ What is claimed is:] [1.] An agricultural implement comprising:a. first and second independent frame sections positioned adjacent to each other, at least one of said frame sections comprising a folding frame section adapted to be raised for transport and lowered for operation, each said independent frame section being arranged to support a plurality of ground working tools;b. a flexible link connector connected to and extending between said frame sections, said flexible link connector allowing the attached frame sections to twist up or down with respect to each other; andc. a scissor limit stop connected to said flexible link connector, said scissor limit stop serving to limit the relative up and down movement between the frame sections when said folding frame section is in the lowered, operating position thereof.
