Stump grinding is a process that excavates the stump of the tree without removing the root. In this situation, a stump grinder is employed to mechanically grind out the stump, leaving fine sawdust as a residue. Typically, tree stumps are ground about 4” below the surface.
Since the stump is ground, it eventually mixes with the soil. This levels the ground and eliminates the need for extra filling. Being non-invasive, stump grinding does not actively remove the underground roots. Once the stump is ground out, the roots die and decay, becoming part of the soil.
On the other hand, stump removal involves pulling the stump from the ground. Normally, it requires the heavy use of force, and the machines employed have high-power requirements.
In essence, the process of stump grinding is preferred for many reasons. It is far easier to execute and uses efficient tools to get the job done. Unlike stump removal, which leaves the environment in a messy state, stump grinding provides a greater level of neatness and environmental friendliness.
