My neighbors with electric lawn mowers were not able to keep their grass cut. I was able to cut my grass, no problem, with my gas mower, and my lawn was the envy of the neighborhood. Especially when I fired up the propane grill.
Two years ago, I bought an EGO 56-volt battery powered lawn mower.
It is vastly superior to the many gas-powered mowers I have owned.
Those of us who do not obsess over un mowed lawns during a slight power outage fare better than those still using a gas-powered mower
