  • Noise

Generally, a lawnmower produces 90 dB to 110 dB sound. But most modern lawnmowers make a healthy noise level to ensure convenient operation use them. 

Compared to an air-cooled lawn mower, a liquid-cooled lawnmower creates less noise because the engine supplies water to the block and head that prevent moving parts from being closer to each other.
