North Haverhill is farming country: hayfields laid out along Route 10, the fairgrounds waiting all year for August, tractors on the road at suppertime. United Ag & Turf keeps lawns in that same landscape, with mowing, trimming, edging and the spring and fall cleanups that follow a valley winter. There is a real difference between a mown field and a mown lawn, and the difference lives entirely in the finish. So the passes get overlapped, the corners get walked, the clippings get blown clear of the drive. Come evening the yard looks like the hayfield's tidier cousin, and that is a fine thing to leave behind.
