Abstract
An agricultural harvester includes a first power unit and a second power unit. The first power unit is couplable with a first primary load, including a threshing system load. A first temperature sensor associated with the first power unit provides a first output signal. A second temperature sensor associated with the second power unit provides a second output signal. A first motor/generator is mechanically coupled with the first power unit, and a second motor/generator is mechanically coupled with the second power unit. The second motor/generator and the first motor/generator are electrically coupled together. At least one electrical processing circuit is coupled with the first temperature sensor, second temperature sensor, first motor/generator and second motor/generator. The at least one electrical processing circuit is configured for selective bidirectional transfer of electrical power between the first motor/generator and the second motor/generator, dependent on the first output signal and the second output signal.
