Used the 20v Dewalt chainsaw yesterday on and off a 5hr clean up where I cut down and limbed out 7 trees ranging from 14” ,12” some 6” and a couple 3” trees . The 14” and 12” were easily 28/30’ full trees. I purposely ran the Dewalt to see how it would handle it. Filled the oil twice as well changed the 5.0 battery once. There were a couple high cuts I needed the extended reach Echo to make for safety but other than that the Dewalt cut the rest. Never had to get the big saw out of the trailer. Love that lil saw!!
