A hoseless hydraulic system is provided which addresses certain safety and efficiency issues known in the art. The hydraulic system includes a shell, an accumulator disposed within the shell, a hydraulic pump at least partly disposed within the shell, and at least one hydraulic motor at least partly disposed within the shell. High pressure fluid communication conduits are substantially located within the shell. The only communication across the shell boundary is mechanical power in, mechanical power out, control signals in, and sensor signals out.
