The Carlton SP7015 series are the most powerful and versatile self-propelled portable grinders made; combining the convenience of a narrow 35-inch backyard machine with the high horsepower of a tow-behind unit to create an extremely productive stump cutter. The SP7015 series offer a huge 70-inch cutting arc while extending below ground 15 inches and above-ground height to an amazing 43-inches. Carlton’s exclusive patented turntable design keeps the weight low on the frame and the engine level during operation. This design also allows the use of a torque magnifying two-stage cutter wheel drive system. Carlton Model SP7015s are now equipped with a Tier 4 compliant turbocharged four cylinder diesel engine. These engines offer up to 12% more horsepower and 33% more torque than the previous models all while being smoother, quieter, and more fuel efficient. These engines do not require diesel exhaust fluid. Subscribe to J.P. Carlton Professional Tree Equipment’s YouTube Channel to hear about new videos as soon as they’re posted!
