I am unable to think of a single good reason to have a gasoline-powered lawn mower. Perhaps someone can enlighten me.

In the meantime, I noticed an excellent tutorial on how to convert gasoline mowers to electric, and recharge them with solar.

Compare the silent, clean and simple electric/solar model to even the smallest lawnmower gasoline engines that pollute 93 times as much as an automobile engine.

The NYT points out that 6 million gasoline mowers were shipped into California in one year. That is the equivalent of 600 million car engines pumping toxic fumes and noise into residential areas. Why?
