ABSTRACT:
A hybrid electric lawnmower is described which includes a first and a second electric motor operating blades and the ability to drive the motors from either 120 VAC line voltage or from a battery pack. There is a user selectable power selection switch for switching between DC or AC power and also a boost and conserve feature which allows for increased speed of the blade as necessary. Running the mower at the conserve setting prolongs battery pack duration per charge. Power supply and control systems allow the user to select operation of the motors in either series or parallel configuration depending on the power source.
