Climb Tully Mountain on an August afternoon and Athol reveals itself as mostly forest, with the roofs and the mown yards showing through like clearings. Cutting Edge Lawn Care keeps a good many of those clearings — mowing through the heavy heat of late summer, trimming back the edges the woods are always trying to take again, hauling off the cleanups when the season turns. Grass grows hard here in July, and then it doesn't, and knowing the difference is most of the job. There is a particular pleasure in the last pass of the day: the smell of cut grass, straight lines, a lawn that looks finished. Serving Athol and the neighboring towns of the North Quabbin.
