ABSTRACT:
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.
