Answer: THE POLLUTION. 

You read that right. In just 30 minutes, a 2-stroke gas-powered leaf blower expels THE SAME AMOUNT of hydrocarbon pollution as 352 Ford Raptor Pickup Trucks would driving in circles around your house over an equivalent time period.

But how can such a tiny tool release such a mind-boggling amount of pollution? It comes down to fuel efficiency, something a two-stroke blower FAILS. The machines heard roaring around our neighborhoods require a mix of oil and gasoline that fails to burn cleanly, and instead gets spewed into our air in the form of a dangerous ground-level ozone. Inhaling these toxins is a known public health threat, increasing the risk of cancer and childhood asthma. 

For the sake of the people we love, we must end this pollution parade. There's too many cleaner, quieter and safer tools to get the job done. 

TL/DR:

How'd we do the math? We looked at the methodology of the EPA federal test procedure (used in this Edmund's study) commonly called the “FTP-75.” In short, this test simulates stopping, accelerating, and general city driving. In 30 minutes of this “FTP-75” test, the driving distance would equal 11.04 miles, or alternatively stated, ~22mph on average. So since 30 minutes of gas leaf blower use is the equivalent hydrocarbon emissions to 3887 miles of Raptor driving, and since one truck would cover 11.04 miles in 30 minutes of this testing methodology, it would take (3887 miles/11.04 miles per hour per truck=352.083) or 352 Ford Raptor trucks running for 30 minutes to drive a combined 3887 miles. So in summary, this is to say that 352 trucks running for 30 mins (at an average of 22 mph in stop and go city driving) is the same hydrocarbon emissions as 1 gas leaf blower for 30 mins! Take your pick: 352 trucks or 1 blower!! It’s no wonder that the landscaping industry emissions now exceeds vehicles in CA and OR.
