The invention provides a supporting leg hydraulic system, an operation vehicle and a control method. The supporting leg hydraulic system comprises a first supporting leg, a second supporting leg, a hydraulic assembly and a control valve. The hydraulic assembly comprises a first oil way, a second oil way, a first hydraulic cylinder, a second hydraulic cylinder and a control valve, wherein the firsthydraulic cylinder communicates with the second oil way and is connected with the first supporting leg, and the second hydraulic cylinder communicates with the second oil way and is further connectedwith the second supporting leg; and the control valve is connected with the first oil way and further connected with the first hydraulic cylinder and the second hydraulic cylinder, and the control valve is used for controlling the first oil way to communicate with the first hydraulic cylinder and the second hydraulic cylinder at the same time or communicate with one of the first hydraulic cylinder and the second hydraulic cylinder. By means of the technical scheme, the supporting leg unfolding efficiency of a user is effectively improved, the labor intensity of the user is reduced, the convenience of supporting leg unfolding work of the user is improved, and potential safety hazards are reduced.
