ABSTRACT:
A level lift system for an implement in which a main frame is flexibly connected to outrigger frames with a wheel assembly carried by each frame. A hydraulic ram is operably connected between each frame and the associated wheel assembly with the rams connected in parallel and with a rotary flow divider interposed in the connection with one end of said rams, whereby fluid pressure is directed to said one end when connected with a pump and fluid is exhausted from said one end when connected with a reservoir. Flow to and from said one end being at substantially equal rates regardless of the relative resistance encountered by said rams.
