The Eterra Vortex is a skid steer stump grinder for taking hardwood and softwood stumps down below grade on land-clearing and tree-removal jobs. A high-torque radial piston motor spins an alloy steel wheel so an operator can grind a stump to chips and move to the next without a tow-behind grinder.

A direct-drive, oil-bath hub puts the motor power straight to the wheel and removes the external couplers and greasing that slow other grinders, and rock guards and wear plates spread the load across the wheel. This is built for tree-service and land-clearing crews that grind stumps regularly and need a wheel and drive that hold up to rock and grit.

Common Applications

  • Stump removal and grinding on tree-service and land-clearing jobs
  • Grinding stumps below grade to clear lots and right-of-ways
  • Following tree removal to take hardwood and softwood stumps down to chips

Selection Notes

  • Two wheel sizes: a 27-inch standard-flow wheel and a 31-inch high-flow wheel.
  • Rated for skid steers supplying 18 to 45 GPM; a case drain is required.
  • Cuts 18 to 20 inches below grade depending on the wheel.
  • Confirm hydraulic flow, case drain, and the coupler for your machine with the supplier before ordering.
