  • The US EPA Small Engine Exposure Study measured operators of petrol lawn mowers, string trimmers, chainsaws and riding tractors (leaf blowers were not among them): short-term carbon monoxide exceeded 120 ppm for some equipment, and CO and PM2.5 exposures may exceed air-quality standards in some uses.

What this means for you

Two-stroke engines burn a fuel-oil mix inefficiently, producing high levels of unburned hydrocarbons and fine particles right at head height. Battery models eliminate the exhaust.
