FAQs
How long do teeth last on a stump grinder?
The life of stump grinder teeth depends on how often you use your PTO stump grinder and what kind of material you’re cutting. For occasional property owners, carbide teeth for stump grinder setups like Farmry’s can last through dozens of medium-sized stumps—sometimes over 60—before needing rotation or replacement. If you’re grinding hardwood or working in rocky soil, they may wear down faster. The good news? Each tip is packaged as a replacement part, so it’s easy to swap out when needed—no complicated tools required.
Can you sharpen carbide stump grinder teeth?
Technically, yes—but it’s not recommended for most users. Carbide teeth for stump grinder setups are super hard—that’s what makes them last so long—but that also means they require diamond wheels or professional sharpening services. Instead of sharpening, most users prefer rotating or replacing them. Farmry’s replacement parts are affordable and pre-aligned, which saves time and ensures consistent grinding.
What’s the difference between steel and carbide teeth for stump grinder?
The main difference is durability. Steel teeth are cheaper but wear out fast—especially when hitting dirt, rocks, or frozen roots. In contrast, carbide teeth for stump grinder models stay sharper 2–3 times longer and are better for heavy-duty jobs. They create cleaner chips and need fewer replacements. For pros or anyone with lots of stumps to clear, carbide is the smarter choice in both performance and long-term value.
How do I know when to replace stump grinder teeth?
Look for signs like slower cutting, more vibration, or irregular-sized chips. A clean-cutting pto stump grinder should make uniform mulch. If you're seeing dust or burnt wood instead of chips—or if the cutting diameter feels reduced—it's likely time to rotate or replace your stump grinder teeth. Farmry teeth come with a simple bolt-on system, so it’s a nice and quick process, even for first-time users.
