Stump Grinder Teeth — Carbide, 4 Piece Set

Teeth are consumable. Plan for that.

Stump grinder teeth wear out faster than any other part we sell. Rocky ground wears them about three times faster. If you're grinding anywhere near stone, buy a spare set at the same time as your first one. Running on dull teeth costs you more in slow machine hours than a new set of teeth costs.

How to tell they're worn out

Most sellers in this business don't publish a clear rule for this, so here is ours: replace the teeth once the carbide tip has rounded off and the tooth is rubbing instead of cutting. You'll hear it before you see it — the machine has to work harder, and the wood chips get smaller.

If you keep running past that point, you start wearing out the pocket — the metal socket the tooth sits in. Pockets are welded on, not bolted on, so replacing one is a much bigger job than replacing a tooth.

Other signs it's time to replace, beyond rounding off

• Chipped or cracked carbide: usually means the tooth hit a rock or buried metal. A chipped tip doesn't get better — it gets worse, fast, once the crack starts catching debris.
• A bent shank: the tooth body itself is bent, not just worn down. That's a sign of overload, not normal wear. Check the rest of the wheel for other bent teeth before you go back to work.
• A sheared or stripped bolt: if a bolt keeps working loose or snaps, it's usually been loose for a while, taking impact instead of holding tight. Replace the bolt along with the tooth — don't reuse a bolt that's already been hammered.

Rotate before you replace, if you can

Some stump grinder teeth are built with more than one cutting edge, so a tooth that's dull on the working face can sometimes be rotated in its pocket for a second edge instead of replaced outright. If yours still look sound otherwise — no chips, no cracks — ask us whether your teeth are the rotating type before you order a full set. On a heavy-use week, check all the mounting bolts before you start; a bolt that works loose under vibration is how a tooth goes missing mid-job.

Which ones fit your grinder

Send us a photo of a worn tooth and tell us the model of your grinder. That's the whole process.

Other sellers hand you a form instead, asking for hole spacing and bolt sizes. That means going out to your machine with a tape measure, to measure a part you already own, on a machine you already bought. We'd rather just look at the photo.

Getting the photo right

Set the tooth on something flat, shoot it straight-on and from the side, and include something for scale — a tape measure or even a coin next to it works. If you can pull the tooth out of its pocket, include a shot of the empty pocket too. That one photo answers almost every question we'd otherwise have to ask you back.
