On Dale's fine recommendation, we have been purchasing a wide assortment of E-go battery-operated tools. We have the 20" electric
lawn mower (that I use to cut grass for fodder for my pigs/chickens/turkeys), chain saw, and string trimmer. We have one heavy-duty battery and 2 smaller regular batteries. I can mow for hours and cycle through all 3 batteries so there is no down time. The $500+ price tag for the mower was hard to swallow, but I got the heavy-duty battery and charger with it, and I'm delighted with how light and yet durable it is. I really put it through its paces and it "takes a licking and keeps on ticking". I have mown 3' grass with the mower, and it did as well as anyone could expect. I love it.
The chain saw is light, quiet and powerful enough to take down mid-sized
trees with ease. Plus it doesn't smell bad. These are all wins in my book. E-go's customer service is really wonderful, too.
The one item I'm not thrilled with is the string trimmer. We've been through 2 already, and they just don't
feed line the way they
should, and clog in heavy grass. My scythe is worlds better for cutting long grass, and using it is a similar physical strain. For trimming walkways and lawn edges the string trimmer is perfect, though.
