742-0571 Fits Craftsman Troy-Bilt MTD Shredder Chipper Blade Kit 781-0490 710-1054

What It Is

This is a replacement blade kit for shredder/chipper attachments on lawn tractors, designed to mulch leaves, twigs, and yard debris. It fits specific Craftsman, Troy-Bilt, and MTD models that use a two-blade shredder system.

Fitment & Compatibility

Before buying, confirm your machine uses the 742-0571 (OEM) or 781-0490 / 710-1054 (cross-reference) part numbers. This kit fits most 42-inch and 46-inch shredder decks with a 1-inch center hole and 3.5-inch blade length. Check your owner’s manual or the existing blade for stamped numbers. It will not fit standard mower decks—only dedicated shredder/chipper attachments. Measure blade thickness (0.1875 inches) and ensure bolt pattern matches (two bolts per blade, 4 inches apart). Avoid assuming it fits all Troy-Bilt or Craftsman tractors; only models with the shredder attachment are compatible.

Key Things to Know

• Quality: Blades are heat-treated steel, comparable to OEM but slightly thinner on some aftermarket versions. Inspect for burrs or uneven edges before install.
• Installation: Moderate difficulty—requires removing the shredder housing (usually 4-6 bolts) and a torque wrench (35-40 ft-lbs for blade bolts). Use thread locker to prevent loosening.
• Gotchas: The kit includes two blades and hardware, but some users report missing washers—check package contents immediately. Reverse-thread bolts are rare but possible; verify rotation direction before tightening.
• Performance: Best for dry leaves and small twigs; wet or heavy debris may clog faster than OEM blades. Sharpen after 10 hours of heavy use.

Should You Buy It

If you own a compatible Craftsman, Troy-Bilt, or MTD shredder attachment and need a budget-friendly drop-in replacement, this kit is a solid choice. It’s ideal for light to moderate yard debris, but skip it if you require heavy-duty shredding or have a different brand attachment—stick with OEM for guaranteed fit and durability.
