The LTC Stump Grinder was developed by a land clearing contractor to solve stump disposal problems created by restrictions on burning and burying land clearing debris. The LTC Stump Grinder is designed to grind stumps and the underground root structure. It turns a relatively slow 200 to 250 rpm, and develops tremendous torque. Competitive grinders turn over 1,000 rpm and are not capable of grinding stumps below ground. The slow rotational speed and high torque characteristics of the LTC Stump Grinder allow it to work in extremely rocky terrain where competitive grinders are not practical.
