Today was the day. I can't push the date up anymore. The lawn looked like a shaggy dog. No sweat! Pop the battery into the Kobalt and life is good. No noxious fumes billowing into my face, no oil to check and no smelly gas cans. Ladies, if you are the only one that cuts the grass you might want to look into this. Lowe's carries the Kobalt and Home Depot has the Eco. I bought the largest because of my big lot. Different sizes means different prices. They are also very quiet. You are not annoying the neighbors at dinner time.
