Late in autumn the marsh grass out toward the bay goes the color of old brass, and Northfield swaps one set of equipment for another. Tnt Cutting Edge Lawn Care spends the green half of the year mowing, trimming and edging on a steady turn, then clears the leaves out of every bed before the cold locks in. Once storms start rolling through, the blades go on the trucks — driveways scraped down to the surface, walkways opened, salt laid where ice gathers near the steps. The best moment in either season is pulling away from a property that is completely squared away. Grass in June, snow in January, the same unhurried attention to both.
