Abstract
A folding implement frame having seven sections in a use position and nine sections when folded. The frame design allows a frame having a width of greater than 27 meters to be folded into a transport position having a width of less than eight meters and a height of less than six meters. The hydraulic system transfers weight to the center frame section during folding and unfolding to enhance stability. The hydraulic system uses accumulators to minimize the amount of oil reduction in the tractor reservoir resulting from extension of the hydraulic cylinders of the implement. Implement raise and lower cycle times are minimized by a helper cylinder to lift the frame main section when the entire implement weight is on the main section and allowing a smaller cylinder to lift the frame main section in the use position for shorter cycle times to raise and lower the implement.
