ABSTRACT:
An implement wing weight transfer apparatus is provided according to the invention for an implement having a first panel hinged to a second panel, with the first panel capable of folding with respect to the second panel. The implement wing weight transfer apparatus comprises a biasing device, with a first end of the biasing device being fixedly connected to the second panel and a second end of the biasing device being slidably connected to the second panel, a first weight transfer link, having first and second ends, with the first end rotatably connected to the second end of the biasing device, and a second weight transfer link, having first and second ends, with a first end rotatably connected to the second end of the first weight transfer link and with a second end of the second weight transfer link rotatably connected to the first panel, wherein in a transport mode the first and second weight transfer links fold up to allow the folding of the first panel with respect to the second panel, and in an operational mode the biasing device exerts a weight transfer bias tension on the first and second weight transfer links.
