Saturday morning in Willow Run sounds like sprinklers ticking and a mower two streets over. Bros That Mow Landscaping, LLC is often that mower — cutting, edging, blowing the clippings clear so the sidewalk goes back to being a clean gray ribbon. Fall shifts the work to leaves and one last low cut before the ground goes hard. Then the same trucks come through with plows and shovels, out ahead of the coffee. It is a straightforward trade, done in daylight and in the dark.
