Rake, Don't Blow

Although leaf blowers may seem cool and convenient, they are extremely polluting, and much less green than simply raking fallen leaves the old-fashioned way.

In one year's time, that little 2-stroke leaf blower engine you hear buzzing up the street pumps out as much smog-forming pollution as many cars, according to the California Air Resources Board, the state's air quality agency. Lawn and garden equipment made before 1997 is responsible for as much as 5% of ozone-forming pollution, according to the Environmental Protection Agency. In addition to the ozone-forming volatile organic compounds, these engines produce fine dust and soot that can damage lung tissue, triggering asthma attacks and other health problems.

Fortunately, regulators have taken notice, and are encouraging manufacturers and the buying public to upgrade to newer, cleaner (as well as quieter) models. Look for electric models, or those approved by the California Air Resources Board, since California has standards that exceed those in other states. When you do use lawn equipment, follow these EPA tips to reduce air pollution:

• Always follow the manufacturer's guidelines for maintenance, and perform routine tune-ups.
• Change the oil and clean or replace air filters regularly, and use the recommended fuel-oil mixture for two-stroke engines.
• For lawn mowers, keep blades sharp and clean the underside of the mower deck.
• Winterize your equipment each fall.

But the cleanest way to clear leaves and storm debris is still to get your hands on a rake.
