There is a rhythm to a mowing route through Charlotte's older subdivisions: pull in, drop the deck, walk the yard for sticks, go. M7 Lawn Services keeps that beat through the long green middle of summer, finishing in the late-afternoon light when the stripes across a front lawn stand out the way they are supposed to. Trimming tightens the yard around the mailbox posts and the porch steps; edging gives the driveway a border you could follow with your eye. Little things, repeated on time, add up to a street that looks settled. The route holds Charlotte, Potterville, Dimondale and Eaton Rapids.
