We have no back yard (paved drive/patio), no grass in side yard and a very small amount of grass in the front yard (lots of flower beds). Because of health problems (we're well into our 70's), we still use a lawn service to mow and weedeat twice a month. But when we get a lot of rain like this past month, and it needs mowing in-between visits from the service, like this month, my husband uses the ERGO battery-operated mower bought at Lowes. He is very pleased with it and has had no problems to date. If fully charged, it will do the entire yard (front and side street section) in one full charge.
