TORO STX-38 Stump Grinder: Real-World Field Testing Results
When you’re investing in professional stump grinding equipment, you need to know it can handle the toughest jobs on your list. That’s why we took two brand-new TORO STX-38 stump grinders out for comprehensive field testing on real stumps – and the results speak for themselves.
I’m Chris Doosey, owner of Mower Supastore, and I wanted to show landscape professionals and hire shops exactly what this machine can do when faced with different stump sizes and hardness levels. Whether you’re grinding out typical tree stumps or tackling massive specimens over a metre wide, the STX-38’s performance might surprise you.
Why We’re Testing the Toro STX-38 Stump Grinder
The TORO STX-38 has become one of the most talked-about stump grinders in the Australian market, and for good reason. With its Intelli-Sweep technology, fully hydraulic operation, and track-driven design, it promises to deliver professional results with less operator fatigue and better fuel efficiency.
But specifications on paper only tell part of the story. Landscape contractors and equipment hire businesses need to see how these machines perform in real conditions, on Australian hardwoods, in actual working situations. That’s exactly what this field test delivers.
The Test Setup: Two Different Stump Challenges
To give you a comprehensive view of the STX-38’s capabilities, we set up two distinctly different grinding scenarios:
Test 1: Standard Tree Stump
Our first test stump represents what most professionals encounter daily – a typical tree stump from a mature tree that’s been felled. This is your standard residential or commercial job where the tree has been cut close to ground level, leaving a stump that needs grinding before landscaping can continue.
In this test, you’ll see how the STX-38’s Intelli-Sweep feature automatically adjusts the cutting head speed based on load. When the cutting wheel encounters denser wood, the system intelligently slows down to maintain optimal cutting power without bogging down the engine. This isn’t just a convenience feature – it translates directly to fuel savings and longer blade life.
Test 2: Large Diameter Stump (1 Metre Wide, 700mm High)
The second stump presented a much bigger challenge – approximately one metre in diameter and standing 700mm above ground. This is the type of stump that separates professional-grade equipment from hobby machines. It’s the job that hire shops need equipment to handle, and landscape contractors can’t afford to turn away.
This test really demonstrates why the STX-38’s fully hydraulic operation matters. There are no belts to slip or break under heavy load, no tension adjustments needed mid-job. The hydraulic system delivers consistent power directly to the cutting head, even when you’re removing this much material.
Key Performance Features We Observed During Testing
Intelli-Sweep Technology in Action
The standout feature during both tests was definitely the Intelli-Sweep system. This technology automatically monitors the load on the cutting wheel and adjusts the sweep speed accordingly. When grinding through tougher sections of wood, you could hear the sweep slow down slightly, maintaining consistent cutting power and preventing engine bog-down. This means:
- Less operator intervention required
- More consistent grinding results
- Better fuel efficiency across the job
- Reduced wear on cutting teeth
Track System Stability
The track-driven design of the STX-38 proved invaluable, especially during the large stump test. The wide footprint and low centre of gravity kept the machine stable even when removing large amounts of material. The tracks also mean you can work in soft ground conditions without sinking or creating damage – crucial for maintaining professional job sites.
Ground Speed and Productivity
Between grinding jobs, the STX-38’s ground speed of 4.5 mph makes a real difference. When you’re moving between multiple stumps on a property or loading the machine on and off your trailer, that extra speed adds up to significant time savings over a work week.
Electronic Fuel Injection Benefits
The Kohler EFI engine started first time, every time during our testing. Electronic fuel injection means consistent performance regardless of temperature or altitude, easier starts on cold mornings, and generally less maintenance compared to carbureted engines.
Who Should Consider the TORO STX-38?
Landscape Professionals
If you’re a landscaping contractor who regularly encounters stump removal as part of site preparation, the STX-38 offers the perfect balance of power and maneuverability. At just 34 inches wide, it fits through most standard gates while still delivering commercial-grade grinding performance. The hydraulic system and Intelli-Sweep technology mean less time adjusting settings and more time completing jobs.
Equipment Hire Businesses
For hire shops, the STX-38 ticks all the boxes. It’s tough enough to handle demanding customers and challenging stumps, yet the TX-style controls make it relatively easy for first-time users to operate safely. The track system reduces the risk of damage to customer lawns, and the fully hydraulic operation means fewer belt replacements and adjustments – that’s less downtime and better return on investment.
Tree Services and Arborists
If stump grinding is a regular part of your tree services, the efficiency gains from the Intelli-Sweep system and the ability to handle stumps up to 18 inches below grade make the STX-38 a serious productivity booster. The machine’s stability on slopes and uneven terrain is particularly valuable for tree service professionals working in varied conditions.
Technical Specifications at a Glance
Here are the key specifications that make the TORO STX-38 such a capable machine:
- Engine: Kohler Command PRO ECV980 EFI (38 HP)
- Cutting Wheel: 22.25 inches diameter
- Maximum Cutting Depth: 18 inches below grade
- Cutting Height: Adjustable up to 35 inches above grade

- Ground Speed: 4.5 mph for efficient transport
- Drive System: Full hydraulic with track drive
- Weight: Approximately 1,750 lbs
The STX-38 combines power with practical dimensions
Real-World Advantages We Noticed
Beyond the manufacturer’s specifications, here’s what stood out during our field testing:
No Belt Maintenance: The fully hydraulic system means you’ll never lose time to broken or slipping belts mid-job. This is huge for hire shops and busy landscape contractors.
Fuel Efficiency: The Intelli-Sweep system’s ability to optimize cutting speed based on load means you’re not wasting fuel running the cutting head at maximum speed when it’s not needed.
Operator Comfort: The TX-style controls are intuitive, and the machine’s stability reduces operator fatigue during long grinding sessions.
Professional Results: Both test stumps were reduced to chips efficiently, with consistent grinding depth and minimal secondary cleanup required.
Comparing Stump Grinder Options
When shopping for a professional stump grinder, you’ll encounter everything from basic walk-behind models to large tracked machines. The STX-38 occupies a sweet spot – it’s powerful enough for commercial work and large stumps, compact enough to access residential properties, and efficient enough to operate profitably.
Compared to belt-driven stump grinders, the hydraulic system provides more consistent power delivery and eliminates one of the most common maintenance headaches. Compared to larger tracked grinders, the STX-38’s 34-inch width means you can access more job sites and still deliver professional results.
Investment Considerations
Quality professional equipment represents a significant investment, but the right machine pays for itself through improved productivity and reduced maintenance costs. The TORO STX-38’s combination of Intelli-Sweep technology, fully hydraulic operation, and EFI engine positions it as a smart long-term investment for businesses serious about stump grinding services.
