ABSTRACT:
An electric starter for a walk-behind, powered, rotary cultivator having a gasoline engine having a crankshaft and a recoil starter connected to the gasoline engine. The electric starter includes an electric motor connected to the crankshaft between the recoil starter and the engine so that activation of the electric motor starts the engine and the recoil starter can also be used to start the engine; a battery connected to the electric motor; a start switch between the battery and the electric motor; and a battery charger. The electric starter is intended for use on cultivators generally having less than about 2 horsepower. The recoil starter is intermittently engageable with the crankshaft through the electric motor. The electric motor may also act as a generator supplying electric current to the battery to charge the battery.
