The U.S. Environmental Protection Agency found that lawn and garden equipment small engines are responsible for 10% of air pollutants nationwide.
In metropolitan areas, the concentration of lawns causes this percentage to increase, in some instances to 33%.
One old gas powered lawn mower running for an hour emits as much pollution as driving 650 miles in a 1992 model automobile.
A fully charged battery pack will allow 35 minutes of cut time. With a person walking 2 mph while mowing, nearly 1/4 of an acre will be mowed per charge. (The Journal of Turfgrass Management estimated the average U.S. lawn size was 1/5 of an acre.)
