A folding implement frame is disclosed having seven sections when in afield use position and nine sections when folded. The frame design allows aframehaving a width of greater than 27 meters to be folded into a transportpositionhaving a width of less than eight meters and a height of less than six meters.Thehydraulic system is used to transfer weight to the main or center framesectionduring folding and unfolding to enhance frame stability. The hydraulic systemusesone or more accumulators to minimize the amount of oil reduction in thetractorreservoir resulting from extension of the hydraulic cylinders of theimplement.Implement raise and lower cycle times are minimized by providing a secondhelper cylinder to lift the frame main section when the entire implementweight ison the main section and allowing a smaller cylinder to be used for lifting theframemain section in the field use position for shorter cycle times to raise andlower theimplement for turns in the field.
