An auxiliary power system for an agricultural implement includes a variable speed hydraulic drive motor configured for receiving hydraulic oil from a tow vehicle, an electric alternator coupled with and driven by the hydraulic drive motor, and at least one auxiliary electrical component onboard the implement which is coupled with and adapted to receive electrical power from the alternator. At least one load indicator provides an indication of a dynamic cumulative electrical load of the one or more auxiliary electrical components. An electrical processing circuit is coupled with the at least one load indicator and the hydraulic drive motor, and is configured to vary the speed of the hydraulic drive motor, dependent on the indicated dynamic cumulative electrical load.
