I've been really happy with my electric zero turn mower I bought a few years ago. It was time to replace my old riding mower anyway. Like you, I bought mine from Lowe's. No $100 annual oil, oil filter, and air slip change. No gas for mowing about 1 acre of grass (not counting the woods or the house) about 20 times per year. And no power added to my power bill because every week when I'm done I always plug it into a 120V outlet that's intermittently powered, only when my home solar batteries are charged enough to power the home without the grid.
Who cares if it's about to get dark that day and there won't be enough spare power to charge the mower's batteries? I don't need it charged again for another week. At some point over the next week I'll have plenty of sunlight to power that outlet and charge the mower by the time I have to mow again.
