This invention relates to the field of hydraulic log splitter technology, and more particularly to a dual-speed, dual-drive hydraulic log splitter, which overcomes the shortcomings of existing technologies. It includes a log splitting platform with an oil cylinder mounted on it. A cylinder is mounted at the top of the oil cylinder, and a splitting blade body is installed at the telescopic end of the cylinder. A motor, a main pump, and a hydraulic control valve are mounted on the outer wall of the oil cylinder. A motor pump is installed at the output end of the motor, and the hydraulic control valve also has a control mechanism for operation. When the cylinder descends, the device operates in two speeds. For small-diameter logs or logs that can be easily split, the fast speed is sufficient. When encountering large logs where the splitting force is insufficient, the valve core is pressed down to the second speed position for slow, high-force splitting operation, improving work efficiency. It also features two drive modes to enhance practicality in different operating environments. Furthermore, it requires both hands to operate, improving operational safety.
