The Toro STX-38 is a professional 38 HP self-propelled stump grinder with a 22.25-inch hardened cutter wheel. At 18 inches below grade, 52-inch head swing arc, and 1,750 lb machine weight, it removes stumps completely on any species for replanting or hardscape installation.
01
Large-Diameter Hardened Cutter Wheel
The large-diameter cutter wheel armed with multiple hardened grinder teeth delivers aggressive stump material removal on any wood species and stump size. Substantial wheel thickness and professional tooth count provide controlled cutting force with every sweep.
02
Dual Hydrostatic Traction Drive
Independent dual hydrostatic drive motors enable precise zero-radius turning and smooth positioning around stumps, roots, and landscape features without manual machine repositioning, allowing efficient movement into and out of every cutting position.
03
Wide Cutter Head Sweep Arc
A generously wide sweep arc removes stump material across the full stump diameter in fewer passes, significantly reducing job time per stump compared to machines with limited swing travel while minimizing the need to reposition the machine.
04
Deep Below-Grade Cutting
The cutter head reaches well below ground level, removing the stump and upper root structure to a depth sufficient for replanting, laying sod, or installing hardscape directly over the former stump location without future heaving or root regrowth.
05
Self-Propelled Hydrostatic Travel
Hydrostatic self-propulsion drives the machine between stump locations, across properties, and around obstacles without manual pushing or pulling, significantly reducing operator fatigue on multi-stump job days and large property cleanups.
06
Compact Towable Design
The compact dimensions and towable weight allow the STX to be trailered to any jobsite with a standard pickup, maneuvered through residential gate openings, and positioned in backyard locations inaccessible to truck-mounted or larger self-propelled stump grinders.
