The subject innovation is, the motor receiving portion formed on the bottom internal fisherman and lower through which the rotation shaft of the motor for driving the blade, the through-hole is a fisherman; Cover unit covering the rotary shaft is formed in the upper parts of the through-hole for penetrating the containment; Spaced power transmission to be provided for each pair of one end rotatably coupled to said cover section bar; Blade which is coupled with the rotary shaft in the lower receiving part rotating with the rotation of the rotating shaft; And equipped with a moving part coupled to the cover portion and the wheel; includes, the electric motor is a fisherman, a ratchet gear for transmitting power in one direction, while rotation is combined with the rotating shaft; A first gear coupled to the transmission shaft engages with the ratchet gear; Coupled to the transmission shaft and a second gear provided in the lower portion of the first gear; Third interlocking gear coupled to the ratchet gear in the lower rotating shaft and fit the second gear; The coupling to the axis of rotation and said third connection portion being joined to the lower portion of the gear; being coupled to each end and rotation of the including, and the power transmission of the pair of bars are connected to a pair of each of the other end bar, connected to a pair of each other end of the rotating shaft and being coupled to pivotably shown coupled rotating shaft connected to rotation, the connecting portion is lower is projected through the lower through-the blade bar is characterized by a manually bush cutting machine which is connected to the connection portion.
Thus, according to the present invention, does not use a motor or engine noise pollution and it can prevent the exhaust pollution as well as the weight is lighter is easy to carry and store.
Further, according to the present invention, because even a user unfamiliar with the lawn mower can be used easily, while controlling the moving speed of the blade compared with the self-winding bush cutting machine it is possible to prevent the risk of safety accident.
