HYDRAULIC CIRCUIT FOR SYNCHRONOUS LIFTOF FLEXIBLE FRAME IMPLEMENTSABSTRACT OF THE DISCLOSUREA hydraulic circuit for synchronous liftof an implement having a center frame and flexiblyconnected left and right wing frames, each framehaving an independent wheel assembly for raisingand lowering the associated frame. A rotary flowdivider is provided in a parallel connection ofhydraulic rams to actuate the wheel assemblies.The flow divider has a section sized to provide thenecessary flow to each ram so that all frames areraised and lowered in unison.
