Lawn Mowers that Don't Use Gas

Recently I've been testing a spate of "gasless" outdoor power tools: trimmers that run off lithium-ion batteries or propane, chainsaws that work on nickle-cadmium batteries and mowers, including a $3299 riding one from Ariens, propelled by electric motors and lead acid batteries.

In this Wall Street Journal story and video, you can see many of the tools in action and get a glimpse of where they perform well and where they fall short. The goal of the new breed of outdoor equipment is less maintenance, fewer emissions.
