Disclosed is a hydraulic control valve assembly of automatic steering system for agricultural machine including a proportional directional valve (). A balancing valve () is arranged between the proportional directional valve () and the steering cylinder. A first shuttle valve () is arranged between the proportional directional valve () and the balancing valve (). The first shuttle valve () is positioned on one side of the proportional directional valve (). An overflow valve () is positioned on another side of the proportional directional valve (). The overflow valve () is connected to a second shuttle valve () and a logic valve () respectively. The hydraulic control valve assembly has a large control power, a rapid response, and is more suitable for the autonomous navigation operation of agricultural machine. Moreover, the system saves more energy, such that the autonomous navigation operation of agricultural machine is more stable.
