A Saturday morning in Franklin Township has a soundtrack, and a good part of it is mowers. Sean's Lawn Mower is one of them — mowing, edging, string trimming and seasonal cleanups, yard by yard, at the scale where you know whose dog barks at the gate. Small operations get to be particular: the same height every visit, the trimmer run along the fence line, the drive blown off before the truck moves an inch. Nothing about the work is complicated. It only has to actually get done, on the day it was supposed to happen.
