Choosing the Right Stump Grinder

A stump grinder uses a spinning wheel fitted with carbide teeth to chip a tree stump down below ground level, letting you replant, pave, or reclaim the space. It's far faster and cleaner than digging, chemicals, or burning. The right machine depends on how large the stumps are, how many you'll grind, and whether you want a self-powered unit or a PTO attachment for a tractor.

Engine power and cutting wheel size determine how quickly you grind and how deep you can go, while the number and quality of carbide teeth affect cutting speed and longevity. Walk-behind and towable gas models suit homeowners and landscapers, self-propelled units ease bigger jobs, and PTO grinders harness a tractor's power for heavy commercial clearing.

Gas vs. PTO Stump Grinders

Gas-powered stump grinders are self-contained and portable, ideal for homeowners, landscapers, and rental use without a tractor. PTO stump grinders mount to a tractor's three-point hitch and draw power from the PTO shaft, delivering strong grinding force for large-scale clearing without a separate engine. Choose gas for standalone flexibility or PTO if you already run a suitable tractor.

Frequently Asked Questions

How deep does a stump grinder go?

Most stump grinders remove the stump several inches below grade, enough to replant grass or landscape over the area. Cutting depth varies by model, so check the specs if you need to clear roots for paving or construction. Grinding lower simply takes a few more passes.

What size stump grinder do I need?

Match engine power and wheel size to your stumps and workload. Smaller gas units handle occasional homeowner stumps, while higher-horsepower walk-behind, self-propelled, and PTO machines tackle large stumps and frequent commercial work. For steady use or big stumps, choose more power and a larger cutting wheel.

What is a PTO stump grinder?

A PTO stump grinder attaches to a tractor's three-point hitch and is driven by the power take-off shaft rather than its own engine. It's a durable, cost-effective option for anyone who already owns a tractor in the required horsepower range, and it delivers strong grinding power for heavy jobs.

Are the cutting teeth replaceable?

Yes. Our stump grinders use replaceable carbide teeth, so as they wear you can swap individual teeth rather than the whole wheel. This keeps grinding fast and efficient and extends the life of the machine. Keeping sharp teeth on hand is key to smooth cutting.
