The streets in Chester run downhill toward the river and the ground between them tilts in every direction at once, a fact any mower learns in its first week of work. TMBR Mowing LLC takes those yards on through the growing season — cutting, string trimming the banks a deck cannot hold, edging walks and drives back to a clean line. Summer in this corner of Randolph County is humid and heavy, the kind of heat that makes an early start feel like mercy. By mid-morning there is a row of finished lawns behind the truck and the day still has some give left in it. Level, trimmed, tidy at the margins — the same standard on a slope as on flat ground.
