That would be a super tool for the gardener.
I use my big Ryobi battery hedge trimmer for harvesting weeds...thus weed control. It does a 24" swath. Like you, I don't often pull weeds out by the
root. It depends upon the situation, but usually I just cut weeds off close to ground level. Using the hedge trimmer I can weed an area in the fraction of the time it would have taken to hand pull it.
My battery hedge trimmer is one of my favorite tools.
