A September Saturday on a street of porches in Hackettstown has a soundtrack, and mowers are most of it. RH Lawn Service is one of them, moving property to property with the same order every time: cut, trim, edge, blow the walk clean, leave nothing behind but lines. Late-season grass grows slower and cuts cleaner, so the results hold all week — which is when a lawn earns its keep, sitting there looking settled. Spring brings the cleanup and the mulch, autumn brings the leaves, and the middle is honest weekly mowing. Simple work, kept up, is what makes a block look loved.
