摘要:
A cutting head for a cord-type mower driven by an engine is disclosed. The cutting head includes a rotor capable of rotating about an axis and a bobbin with a cord wound on it. The bobbin can rotate relatively to the rotor about the axis in the rotor. The cutting head includes two types of cord feeding systems. The first cord feeding system automatically feeds a cord in response to cord wear. The second cord feeding system feeds a cord in response to a manual tapping operation executed during driving of the cutting head. The second cord feeding system disconnects one of the bobbin and rotor from the engine in response to the tapping operation.
