Abstract: A mowing head includes a case, which is detachably attached to a rotary shaft located at a distal end of a manipulating rod of a mower, and a weed cutting tool, which is attached to the case. The bottom portion of the case is formed of resin. A protecting member is arranged in the bottom portion and insert molded using a material having an anti-wear resistance characteristic that is superior to that of the resin.

Abstract: A protection cover for a trimmer is disclosed. The protection cover includes a protection portion that is comprised of plural elastic members. The protection portion prevent chips such as grasses trimmed or small stones inside of the cover. Each of the elastic members is shaped to a strip in an embodiment. The protection cover also includes a member of adjusting a vertical position of the protection portion.

Abstract: 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.
