DUAL SOURCE STARTER SYSTEM FOR AN ENGINE

A gasoline grass trimmer includes an internal combustion engine (ICE) (15), a starter system (1) configured to start the engine (15). The present invention relates to an engine starter system (1) that can transmit external rotating force or using internal Pulling Wheel System (4, 8) generated rotational force through the 'Dual Force Clutch' (7), 'Buffering Spring' (9) and drive the 'Driving Plate' (2) to start the (ICE) (15). The present invention states that external rotational force from electrical power driven device (5.1 and 5.2), such as power tool, can be applied through the 'External Rotating Force Connector' (5) to start up the ICE. Or if such electrical power driven device electrical rotating device is not available, the ICE can also be started by the built-in Pulling Wheel System (4, 8) of this Dual Source Starter System.
