The decibels of lawn mowers are louder, and they are less developed as electric vehicles. At present, most of the energy supply on the market uses fuel or electricity. Therefore, we improved the power supply method of the lawn mower, and fed back the noise made by agricultural vehicles to ourselves. With sound wave and solar energy as the main power generation, seismic wave power generation as a supplement, so that the machinery can achieve the purpose of energy saving and carbon reduction. By changing the power generation module of the machine, the lawn mower can achieve the effect of energy reuse.
