Trencher Teeth — 8 Piece Set (Cup, Shark or Carbide)

Which teeth do you actually need?

That depends on what you're digging into, not on what machine you own. This is the question that decides whether a set of teeth lasts a whole season or just one afternoon — and most sellers of teeth don't actually ask it.

• Sand and loam: standard cup teeth. Fastest digging, cheapest set.
• Clay: shark teeth. Cup teeth pack full of clay and stop cutting.
• Rock and frozen ground: carbide teeth. Anything else will wear out two full sets in a single day.

Not sure which ones came off your machine?

Send us a photo of a worn tooth and tell us which trencher it came from. We'll tell you which set fits.

Other sellers in this business hand you a measurement form instead — overall length, hole count, bolt size, and the spacing between holes. That means going out with a tape measure to measure a part you already own, on an attachment you already bought. We'd rather just look at the photo.

Getting the photo right

Lay the tooth flat, shoot it straight-on and from the side, and set something next to it for scale — a tape measure or a coin both work. If you can, include a shot of the chain link it bolts to as well. That tells us the pitch and width of your chain, not just the tooth style, and it's the fastest way to get you the right set on the first try.

When to replace them

Most sellers in this business don't publish a clear rule for this, so here is ours: replace the teeth once the carbide tip is gone and you're cutting with the bare steel body. Running past that point wears out the holder — the metal piece the tooth bolts into — and a holder costs a lot more to replace than a tooth does.

Rock and frozen ground wear teeth about three times faster than normal digging. If you're working in either one, buy a spare set up front instead of losing a day later waiting on a parts order.

Signs beyond "worn down to bare steel"

• The chain skips or bounces instead of biting in. That usually means one or more teeth are worn shorter than the rest, so the chain rides up instead of cutting evenly.
• A tooth is missing outright. A missing tooth throws the chain out of balance. You'll feel it as extra vibration, and it speeds up wear on the teeth that are left.
• Chipped or cracked carbide on an otherwise fresh tooth. That's usually a rock or buried object, not normal wear. Check the rest of the chain for other chipped teeth before you go back to digging in the same spot.
