Hydrostatic drive land leveller

The invention discloses a static hydraulic-transmission land leveller. The variable hydraulic pump in the static hydraulic-transmission system is transmission-linked with the engine by the coupling, the outupt axes of variable hydraulic motors are respectively transmission-linked with the input axes of deceleration balance boxes and the outer axes said boxes are respectively transmission-linked with the wheels. It has advantages of simple construction, reliable transmission and speed changing and low cost and so on.
