A hydraulic power system having first and second hydraulic power converters in which the speed of the second power converter is proportional to the speed of the first power converter. The first hydraulic power converter includes a plurality of hydraulic power producing elements. At least one of the power producing elements provides power for power driving, and at least one of the power producing elements pumps hydraulic fluid. The hydraulic fluid is connected to and drives the second hydraulic power converter at a speed proportional to the speed of the first power converter.
