GET TO KNOW THE VORTEX The Vortex Stump Grinder features a high torque output radial piston motor which is highly efficient, converting close to 95% of the hydraulic energy into horsepower. The direct drive system is an oil bath enclosed hub system, meaning there are no external couplers and nothing to grease. The asymmetrical high strength alloy steel wheel provides great visibility and features replaceable teeth, rock guards, and abrasion resistant wear plates. UNDER THE HOOD The Vortex Stump Grinder for Skid Steers utilizes an extremely efficient hydraulic radial piston motor that converts your machine's hydraulic flow directly into grinding power. Capable of grinding hard and soft woods, the asymmetrical cutting wheel not only provides great visibility, but also maximizes the life of the cutter teeth.
