1. A method of dissipating power in a propelled machine having an electric drive, comprising:
- converting undesired power to electric power by the electric drive; and
driving an internal combustion engine with at least a portion of the electric power prior to substantially dissipating power with a resistive grid by providing at least another portion of the electric power to the resistive grid.

16. A method of dissipating undesired power in a propelled machine having an electric drive, comprising:
-
driving an internal combustion engine by the undesired power; providing undesired power to at least one of an energy storage component and an electric powered accessory of the propelled machine; providing undesired power to a resistive grid after the driving an internal combustion engine by the undesired power reaches a maximum limit; and applying at least one brake of the propelled machine. - View Dependent Claims (17, 18, 19, 20, 21)

22. A propelled machine, comprising:
-
a first means for dissipating undesired power, including an engine means; a second means for dissipating undesired power, including a resistive grid; a third means for dissipating undesired power, including a brake means; an electric drive; and a controller configured to prioritize the use of one of the first, second, and third dissipating means so that the dissipating means having the highest priority dissipates power to a predetermined limit if more than one dissipating means is required, wherein the first dissipating means has a first priority, the second dissipating means has a second priority, and the third dissipating means has a third priority.
