Our Weed Eater/Whacker or whatever is from Home Depot thee green brand, Can't remember name electric. It spins faster and does a great job an is lighter but it won't do 3-4 acres of edges stream and home etc.
One of our blowers is same brand electric and works very well but is no long winded enough for entire length of driveway nor near as strong as our backpack blower. They get energy density of batteries about four times more and they might outsell gas. I need to do some trimming but our self propelled mower is still too much now so a light weight electric self propelled might be a great thing for me.
