eenI'm getting up in years, mow and acre and a half, and the Toro I used for trim and clean was driving me into the ground. Today my Son bought me a fathers day gift of a greenworks 40V lithium mower at Lowes. It has two batteries, 110 minutes of endurance and the cool part is it uses one battery at a time so you can charge one while you use the other. I trimmed 1.5 acres today and didn't deplete both batteries but I intentionally drained them both to recharge from zero for the first time. So far I'm good to go with a light weight composite mower for this old man
