April storms reach Lincoln from the west, out over the Oklahoma line, and after two days of rain the whole town turns a green so loud it looks lit from underneath. GrassWorks Manufacturing is out in the middle of that surge, when grass gains an inch overnight and every yard is asking for its first serious cut. Spring cleanup clears the winter's litter of sticks and matted leaves, then mowing, string trimming and edging bring the season back under control. The reward is immediate and unmistakable from the road, which few jobs can claim. Through the summer the rounds settle into a rhythm, staying a step ahead of grass that would rather run wild.
