Simple Steps to Reduce Mower Emissions
 Mow late in the day - To reduce the amount of ozone that will form, mow after 7pm. Avoid mowing altogether on Ozone Alert! days. The harmful ozone causing fumes emitted by mowers are nitrogen oxides (NOx) and volatile organic compounds (VOC). These are more likely to form harmful ozone when the weather is hot and sunny. Mowing in the evening will help reduce the amount of ozone that forms.
Keep your equipment well-tuned - Well tuned equipment runs more efficiently, uses less fuel, and emits less pollution. Keep your blades sharpened, too. This simple practice will not only benefit your lawn making it more resistant to disease, but you will mow quicker and that means less air pollution and less wear and tear on your body, too!
Avoid gas spills - Save money and protect the air we breathe by using a funnel or a spill-proof can. Americans spill and estimated 17 million gallons of gasoline each year refueling small engines such as lawn care equipment. The vapor from gasoline spills is also a cause of air pollution.
Spill proof gas cans are available in stores.
