Self-powered stump grinders are excavator attachments capable of grinding stumps fast without hydraulics or dedication to a carrier.
Units are powered with Cummins 170- or 275-horsepower engines. Sneller says all the power goes directly to the patented cutting wheel for optimal grinding. Patented teeth are quick and easy to change with no bolts. Remote control operation and heavy construction help operators grind up to 6 acres per day, according to the company.
