I took the blade off of my mower today, I have a guy sharpen the blade for me when it needs it. He also runs a small engine repair shop. He said he is going to have more business than he can handle because gas powered lawn mowers are going away. Several lawn mower companies have already discontinued gas powered mowers, replacing them with electric mowers. He said people are going to hold on to their gas powered mowers as long as possible, meaning he'll be doing repairs and rebuilds. He said people are finding out the batteries for these mowers only last about 2 years, then they have to be replaced. Replacement cost is as much as the mower was. Battery technology needs to be better to bring replacement costs down if they're going to shove these things down everyone's throats...
