Powered by Mean Green Lithium Energy Modules, our mowers offer all day mowing with extreme power and stealthy operation. With available horsepower exceeding most commercial gas mowers in their classes and maximum torque from the start, Mean Green Mowers prove that cordless electric mowers can be powerful and extremely quiet. The loudest our mowers will get is 80 db, where gas mowers are 95-100 db. For every 6db difference in sound, noise doubles. So, our 80db mower is less than half the noise of a 86db mower.
