The invention relates to a hydraulic system applied to an agricultural vehicle. The hydraulic system comprises a hydraulic traveling system, which comprises an engine, a fuel tank, and a duplex plunger pump, a shunt valve, a damping hole, a left front wheel motor, a left rear wheel motor, a right front wheel motor and a right rear wheel motor which form a closed loop. In high speed driving, high pressure hydraulic fuel produced by the duplex plunger pump enters the left front wheel motor and the right front wheel motor, low pressure fuel output by the left front wheel motor and the right front wheel motor reenters the duplex plunger pump, and thus a closed circulation is formed; in low speed driving, high pressure hydraulic fuel produced by the duplex plunger pump is equally shunted into two ways of hydraulic fuel, one way of hydraulic fuel directly enters the left front wheel motor, the other way of hydraulic fuel passes a normally open solenoid valve to enter the right front wheel motor, finally the two ways of hydraulic fuel are gathered together and return to the duplex plunger pump, and thus the closed circulation is formed. The hydraulic system applied to the agricultural vehicle is driven by full hydraulic pressure, is a self-propelled machine, and can run without a tractor.
