An agricultural vehicle including plurality of engines, a plurality of mechanical loads, a plurality of electrical generators, a plurality of electrical loads, at least one load sensor, and a controller. The plurality of engines includes a first engine and a second engine. The plurality of mechanical loads includes a first mechanical load and a second mechanical load. The first mechanical load is coupled to the first engine and a second mechanical load is coupled to the second engine. The plurality of electrical generators includes a first generator and a second generator. The first generator is coupled to the first engine and the second generator is coupled to the second engine. The plurality of electrical loads can be separately coupled to the first generator or the second generator. The at least one load sensor is configured to produce a signal representative of the first mechanical load on the first engine, the second mechanical load on the second engine, a sum of electrical loads on the first generator, and/or a sum of electrical loads on the second generator. The controller is configured to shift at least one of the plurality of electrical loads between the first generator and the second generator dependent upon the signal.
