Loew's Kobalt brand 21" I believe, 80 volt rear-wheeled powered mower, was a close-out our son bought for his house, approx. 11K sq ft. apart from the building, rear porch & driveway/sidewalk, call it something between 6-7K sq. ft. Was offered with one ? amp hr battery of moderate capacity, he got a more-powerful one also. I borrow it now for our home, and it does the cut of a slightly smaller yard on the larger of the two batteries. You hit taller grass, it speeds up. No issues in 2 seasons. I was skeptical at first when he said he was getting one, but truthfully I like it more than my Craftsman 21" front-wheel powered 6 HP IC engine mower. That's a few years old, bought new, and for some reason it's become temperamental. I disassembled and cleaned the carburetor within the past year, and flushed the gas tank, new sparkplug, new air filter, but suddenly it decided not to work. I borrowed our son's electric, and was impressed by how easy it operates. I mentioned getting one to replace my gas mower, he told us just come & borrow it whenever; we're < 1 mile apart, so that's convenient. Height adjustment is easy.
