PROBLEM TO BE SOLVED: To provide a technique enabling a cutting blade to be driven with sufficient torque even by a small motor. SOLUTION: The bush cutter is equipped with an operation rod, a cutting blade unit installed in the front terminal of the operation rod, a body unit installed in the rear terminal of the operation rod, and a transmission shaft installed in the inside of the operation rod. A cutting blade is supported rotatably by the cutting blade unit. A motor for driving the cutting blade is installed in the inside of the body unit. A first speed-reducing mechanism is installed in the body unit, and a second speed-reducing mechanism is installed in the cutting blade unit to enable the output torque of the motor to be amplified by two stages.
