Hydraulic system for self-propelling tomato harvesters

The utility model relates to a hydraulic system for agricultural harvesting machines, in particular to a hydraulic system for self-propelling tomato harvesters. The hydraulic system comprises five independent hydraulic circuits, which share an oil tank, and a wind cooler and a return oil filter are arranged on a main return oil passage. The hydraulic system has the advantages of stable transmission and reliable performance, and can easily carry out a variety of complex mechanical actions, such as lifting, transmission and steering, and when the hydraulic system is used along with a corresponding tomato harvester, the tomato harvester can have a power system with excellent performance, and thereby can carry out tomato-harvesting operation at high quality and high efficiency.
