Gasoline-powered engines seem to be on their way out, as people become more aware of their contribution to global warming. While cars have experienced the most significant disruption by electric engines, lawn mowers are catching up. The preference of electric lawn mowers is growing (see top products in UK), not just for their energy efficiency, but also for the fact that they are quiet. However, like the electric car engine, electric lawn mower engines have a limitation of range. A common question by people looking to buy them is, how much lawn can an electric lawn mower handle?
