Those electrics seem only good for an hour of mowing, then take 10 hours to recharge.There are electric riders now. But they seem overpriced and there isn't much selection. I know Ryobi has a tractor and I think they now have a zero turn. They use golf cart batteries for these, not lithium ion. I have a self propelled push mower by Ryobi and I like it. But it sometimes needs a second battery to finish my less than half acre lot. It works fine but it should for what it costs. The lack of noise is nice but if I had to pay for my battery powered mower, I would not have it (I got it under the HD seeds program).
