Mower with Engine-Driven Blade and Electrical Propulsion of the Invention A self-propelled robotic or autonomous mower includes an internal combusti on engine directly driving mowing structure such as a single blade or reel, or multiple blades or reels. Drive wheels are driven by one or more electric motors powered from a source including batteries and an engine-driven alternator. A controller connected between the wheel motors and the source and to a navigation system controls the wheel drive and steers the mower over a selected path. The mowi ng structure may be driven from the engine through a direct clutched or unclutched connection to the engine drive shaft, a belt drive, a hydraulic drive, or another similar direct drive arrangement which eliminates the limitations of an electric bla de or reel drive.
