The fairgrounds fill in late August and the whole town smells like fried dough and trampled grass, which is a good reminder of how much punishment a lawn can absorb. Lawnsmith Landscape Construction Inc. keeps Marshfield yards on the other side of that — regular mowing, clean edges, trimming where the machine cannot go, cleanups spring and fall. Once the gates are chained shut and the snow starts, the trucks turn to plowing drives and opening walks ahead of the morning. The pleasure is in the change of gear: one week a mower deck, the next a plow blade. Both jobs come down to showing up when you said you would.
