WORK MACHINE WITH AUXILIARY POWER UNIT AND INTELLIGENT POWER MANAGEMENT
First Claim
1. A work machine, comprising:
- a primary power unit having a rated primary output, said primary power unit being couplable with at least one primary load, said at least one primary load including a propulsion load;
an auxiliary power unit which is mechanically independent from said primary power unit, said auxiliary power unit having a rated auxiliary output which is smaller than said rated primary output, said auxiliary power unit being couplable with at least one external load, said at least one external load including an operator initiated load; and
at least one electrical processing circuit configured for selectively coupling said primary power unit with at least one said primary load, and for selectively coupling said auxiliary power unit with at least one said external load.

Abstract
A work machine includes a primary power unit having a rated primary output. The primary power unit is couplable with at least one primary load, including a propulsion load. An auxiliary power unit is mechanically independent from the primary power unit, and has a rated auxiliary output which is smaller than the primary output. The auxiliary power unit is couplable with at least one external load, including an operator initiated load. At least one electrical processing circuit is configured for selectively coupling the primary power unit with one or more primary loads, and for selectively coupling the auxiliary power unit with one or more external loads.
