PURPOSE: A grass cutter is provided to improve a working efficiency of a worker and to improve power performance by emitting heat from an internal engine to outside. CONSTITUTION: A grass cutter comprises an engine(120), a rotor, a clutch, a body pipe(100), a cutting blade(114), an air guide, and an air hole. The engine generates power by combusting fuel in a combusting chamber. The rotor rotates the power of the engine. The clutch controls whether a rotatory power generated by the rotor should be transferred to the cutting blade or not according to a selection of a user. The pipe controls a working location and direction by a grasp of a user. The cutting blade rotates by the rotatory power transferred through the body pipe. The air guide and the air hole respectively guides and discharges air generated by the rotation of the rotor to outside. |
