Stump Grinding

A stump grinder is a stand-alone power tool or equipment attachment that removes tree stumps by means of a rotating cutting disk that chips away the wood. Stump grinders come in a variety of sizes from the size of a lawn mower to nearly as big as a large truck. Most accomplish their task by means of a high-speed disk with specially designed teeth that grind the stump and underground roots into small chips. A typical stump grinder incorporates a cutter wheel with fixed carbide teeth. The cutter wheel movements are controlled by hydraulic cylinders to push the cutter wheel through the stump and to raise and lower the cutter wheel.
