PROBLEM TO BE SOLVED: To provide a working machine in which weeds are hard to be grown over a long term without increasing a burden of a worker.SOLUTION: A working machine 1 includes: a rotating body 12 rotationally driven by an engine body 21 in the case of work for mowing weeds from the ground a magnet 74 fixed to the rotating body 12 and rotating along with the rotating body 12 and a coil 73 provided in contiguity with the rotating body 12, and generating a high voltage capable of destroying cell membranes of the weeds when the magnet 74 rotating along with the rotating body 12 approaches and passes. The high voltage generated by the coil 73 is applied to grass growing from the ground.
