Eterra Vortex Excavator Stump Grinder
Eterra’s Vortex Stump Grinder removes tree stumps efficiently with a high-torque radial piston motor and direct drive system that converts 95% of hydraulic energy into cutting power, ideal for excavators requiring case drain.
Key Features
The V27 model uses a 27″ non-symmetrical wheel (18–30 GPM) while V31 handles high flow (30–45 GPM) with a 31″ wheel; both feature 12 teeth, 3 rock guards, oil-bathed enclosed hub (no greasing), Grade 50 steel housing, and upgraded rubber guard to contain chips. Anti-cavitation design eliminates check valves, reducing failure points; high-visibility wheel and protected lead tooth enhance safety and precision. Footrest included; cuts 18–20″ below ground.
Model Options
V27 for standard flow (450–700 RPM), V31 for high flow (450–735 RPM); skid steer and mini versions also available for versatility.

Vortex grinder, universal excavator mounting plate, hydraulic hoses, flat-faced couplers, case drain line/coupler, owner’s manual.
