Stump grinding is the process of removing a stump that is currently lodged in the ground through the use of a machine called a "stump grinder." This machine has a large heavy duty wheel-blade with sharp teeth. The blade spins around rapidly until the stump is "ground" out. The stump grinder works like a chipper at ground level. We make passes back and forth over and through the stump with the machine until the stump is ground 4-12 inches below the surface.
