Been thinking here. All the new rav are batteries. Thinking maybe trying it but strictly to my residential crews. They see little trimming compared to our large accounts. That way if things break, things don't start, etc maybe try a battery powered unit. Yes, we always have extra's but its running back to shop, its lost time bc the trimmer doesn't start - could be hole in fuel line which happens, leaky gasket out of the tank, slowly dripping gas down the leg, on the boots, on the grass. I don't know - anyone going or doing this route? I have looked at the dewalt ones which I have like 50 batteries. I looked at Toro's and the ecore. But...what about rain, damp weather. Gas powered ones, who cares, we trim in the rain, sit in the back of the truck in the rain during the day, etc.. That's a concern with battery units.
