AGRICULTURAL HARVESTER WITH DUAL ENGINES AND ELECTRICAL POWER COUPLING
First Claim
1. An agricultural harvester, comprising:
- a first power unit having a first rated output, said first power unit being couplable with a first primary load, said first primary load including a threshing system load;
a second power unit having a second rated output, said second power unit being couplable with a second primary load, said second primary load including a propulsion load;
a first motor/generator mechanically coupled with said first power unit; and
a second motor/generator mechanically coupled with said second power unit, said second motor/generator being configured to electrically drive at least one external load, said second motor/generator and said first motor/generator being electrically coupled together.

Abstract
An agricultural harvester includes a first power unit having a first rated output. The first power unit is couplable with a first primary load, including a threshing system load. A second power unit has a second rated output. The second power unit is couplable with a second primary load, including a propulsion load. 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 is configured to electrically drive at least one external load. The second motor/generator and the first motor/generator are electrically coupled together.
