Meet the Vortex Excavator Stump Grinder
The Vortex Excavator Stump Grinder features a high-torque radial piston motor and integrated direct drive system, converting nearly 95% of hydraulic flow into real horsepower. Its oil-bath enclosed hub eliminates external couplers and constant greasing, reducing downtime and maintenance needs.
The asymmetrical, high-strength alloy steel wheel provides excellent visibility while grinding and evenly distributes workload across 12 replaceable cutter teeth, rock guards, and abrasion-resistant wear plates. Built from A572 Grade 50 steel, the rugged housing can grind stumps up to 18 inches below ground. An elongated rubber chip guard absorbs debris impact and minimizes chip buildup, keeping your work area cleaner and safer.
Whether you’re clearing land, preparing sites, or handling forestry work, the Vortex Excavator Stump Grinder delivers reliable, consistent, and heavy-duty performance for excavators.
