Mid-June in Harlem Township is all sprinkler hiss and cut-grass smell, the kind of morning where a lawn grows an inch overnight and dares you to keep up. Lawncare Unlimited keeps up — mowing on a set weekly rotation through Machesney Park, trimming out the fence lines and light poles, edging the drives back to a clean margin. The neighborhoods here run long and level toward the Rock River, and level ground shows off a straight pass beautifully. Clippings get blown off the concrete before the truck moves, because a finished yard includes the sidewalk. Come November the season closes with a cleanup that takes the leaves off the turf before winter sets on it.
