Ashburnham's ground is glacial leftovers — sand, cobble and granite ledge shouldering up through the lawns like knuckles. Dirt Works Pro mows, edges and trims across that uneven footing, learning where the deck has to lift and where the turf runs deep and easy. It takes a certain touch to keep grass looking even over a hillside that changes character every ten feet. Spring cleanups pull out the sticks and grit winter left behind; autumn cleanups take the leaves off before the ground locks up. A lawn that looks level on land that plainly isn't isn't luck — that is the whole accomplishment of the job.
