Abstract
A power distribution system includes a prime mover and a hydraulic drive system. The hydraulic drive system includes an accumulator to store energy and supplement that available from the prime mover. A control monitors torque imposed on the prime mover and utilizes energy stored in the accumulator to offload the prime mover when its operating conditions are to be changed. Effecting a change under reduced load conditions mitigates inefficient operation of the prime mover.
