Eterra Attachments Stump Grinder | Vortex | 27"-31" Cutting Wheel | 18"-20"+ Cutting Depth | For Standard & High-Flow Skid Steers
DESCRIPTION
The Eterra Vortex Skid Steer Stump Grinder Attachment is designed for heavy-duty stump removal, capable of grinding stumps up to 18 inches below ground. Featuring a high-torque radial piston motor, this grinder converts 95% of hydraulic energy into horsepower, ensuring efficient performance with minimal energy loss. The direct drive system with an enclosed oil bath hub eliminates external couplers, reducing maintenance and increasing reliability.
Built with high-strength ASTM A572 Grade 50 steel, the Vortex is engineered to withstand demanding conditions. The asymmetrical alloy steel cutting wheel enhances visibility for precise positioning, while replaceable cutting teeth and rock guards extend the lifespan of components. A rubber chip guard controls debris, ensuring a cleaner and safer workspace.
