Abstract The invention discloses an electro-hydraulic walking system of a skid steer loader and a control method, and relates to the technical field of engineering machinery, and the control method comprises the following steps: acquiring action information of a handle; the displacement control valve is controlled to act according to the action information of the handle, and the control current output to the displacement control valve is controlled; the displacement of the walking main pump and oil outlet of the oil outlet are controlled through the displacement control valve so as to control the rotating speed and the rotating direction of the first motor and the second motor. According to the control method, the action of the displacement control valve and the control current are controlled in an electric control mode, and compared with a hydraulic control mode in the prior art, automation and remote control of the control process can be achieved easily; in addition, a hydraulic rubber pipe is replaced by the electr
