MTD Genuine Parts 490-110-M135 Mulching Blade for 30-Inch Cutting Decks, Compatible with Various Troy-Bilt, Yard Machines, Huskee, Bolens, Craftsman, and More

What It Is

This is a genuine MTD mulching blade (OEM part 490-110-M135) designed for 30-inch cutting decks. It replaces standard blades to chop clippings finer for nutrient recycling, ideal for mowers used on flat lawns where bagging isn’t needed.

Fitment & Compatibility

Check your deck size first: This blade fits only 30-inch cutting decks, not 42-inch or other sizes.
Brand & model: Compatible with Troy-Bilt, Yard Machines, Huskee, Bolens, and Craftsman mowers that use a 30-inch deck—but not all models. Verify your mower’s model number against MTD’s official compatibility list.
Measurements: Blade length is approximately 15.5 inches (center hole to tip), with a 1-inch diameter center hole and 5-point star pattern. Confirm your existing blade’s hole pattern matches.
OEM vs aftermarket: This is genuine MTD, not a universal fit. If your mower uses a different OEM blade (e.g., Oregon), this won’t work.

Key Things to Know

• Mulching performance: Requires a mulching plug or kit (sold separately) to block the discharge chute; without it, clippings will still exit the deck.
• Installation difficulty: Easy—remove the old blade with a socket wrench, install this one with the air-lift wing facing up. Torque to 70–90 ft-lbs.
• Balance check: Always test blade balance after mounting; an unbalanced blade causes vibration and uneven cut.
• Common gotcha: This blade is narrower than standard high-lift blades—it won’t throw clippings far, so skip it for wet grass or thick growth.

Should You Buy It

Buy this if you have a 30-inch MTD/Troy-Bilt mower and want finer clippings for lawn feeding without bagging. It’s a reliable OEM part with strong reviews, but skip it for wet or tall grass—you’ll need a high-lift blade instead.
