North of Battle Creek the land lifts into low ridges, and the yards up there catch the wind and the full afternoon sun. Impact Lawn & Landscape L.L.C. mows them on a weekly turn — even passes laid in stripes, trimming close around trees and posts, edges cut sharp along drives and walks, mulch worked into the beds, cleanups in spring and fall. July heat is the test; keep the height right and the color holds through it. Standing at the road afterward, watching the lines run straight across a whole front yard, is the best part of the day. Then the trailer gate goes up and the route moves on.
