A log splitter of the type having a vertical frame formed of two spaced H-beams, a support movably mounted on the frame, a wedge assembly mounted on the frame, and a power drive for splitting a log by forcing the wedge into the log, and which includes two counter-balancing constant force springs arranged to apply an upward force to the wedge assembly sufficient to keep it from moving downwardly when the wedge assembly is not clamped to the frame, the springs being positioned in channels of the H-beams and connected between the ends of the H-beams and opposite ends of the wedge assembly with the object of reducing the physical exertion required in the operation of the log splitter and at the same time reducing the risk of personal injury that might be caused by a free falling wedge assembly.
