Troy Bilt Chipper 12 Chipper Shredder Flails/Hammers Troy-Bilt 1756904, 1915700HT and 1915700ZMA

What It Is

These flails/hammers are replacement cutting teeth for Troy-Bilt Chipper 12 shredder chippers. They shred leaves, brush, and yard waste into fine mulch inside the machine’s chamber.

Fitment & Compatibility

• Exact fit for: Troy-Bilt Chipper 12 models 1756904, 1915700HT, and 1915700ZMA. Also compatible with OEM part numbers 1756904 and 1915700.
• Check your model number – located on the engine cowling or frame tag. Do not rely on machine name alone.
• Measure your old flail – these are approximately 4.5” long with a 0.5” mounting hole. If yours differ, they won’t fit.
• OEM vs aftermarket – this is an OEM-style replacement, not genuine Troy-Bilt. Verify bolt hole spacing matches before buying.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, possibly a breaker bar for stubborn bolts. Expect 30–60 minutes.
• Replace in sets – always replace all flails at once to maintain balance and shredding performance. Mixing old and new causes vibration and uneven wear.
• Torque bolts to spec – use thread locker and tighten to 20–25 ft-lbs. Loose flails can fly off or damage the rotor.
• Common gotcha – the mounting bolts are often rusted or seized. Soak with penetrating oil a day before removal.

Should You Buy It

If you own a Chipper 12 and your flails are dull, chipped, or missing, this is a solid, affordable replacement. Rated 4.6/5 by users for fit and durability. Best for DIY homeowners who want to restore shredding performance without paying for genuine Troy-Bilt parts. Not for heavy commercial use.
