Battery operated all the way (depending on yard size). For me I can easily do around all the edging, fence (inside and out), and anything else I need and not have to worry about mixing gas & oil.
just for fun I googled "Kobalt gay"
my suspicions were confirmed
I just bought the dewalt trimmer yesterday and I like it
If you get that kind of performance out of the 20v that would be more than enough for my yard. by thinner batts do you mena like 3 amp? The only thing I need to decide then is if I want to jump up to the 60v so I can use that batt for icefishing. Could always buy just the batt for fishing I suppose but if I have the 60v batt I might as well have the bigger trimmer...
