B1PD5068 (Set of 3) 21.625 inches Long Mulching Blades Fits John Deere Fits JD Mowers

What It Is

This is a set of three 21.625-inch mulching blades designed for John Deere lawn tractors with 54-inch decks (typically the 54C or 54-inch Accel Deep Deck). Mulching blades feature a curved, wing-like design to recirculate grass clippings for finer cutting and nutrient return.

Fitment & Compatibility

• Deck size: Must be a 54-inch deck. Blades are 21.625 inches long, center hole is 1-inch round with a 5-point star pattern.
• Model fit: Commonly fits John Deere X300, X500, X700 series with 54-inch decks, plus select D100, D200, and D300 series with 54-inch decks. Also fits some older 400/500 series tractors.
• OEM cross-reference: Replaces John Deere part numbers B1PD5068, B1PD5068 (OEM), and M155235. Not a genuine John Deere product—aftermarket.
• What to check: Measure your existing blade length (center hole to tip) and verify the drive star pattern. Confirm your deck model number (stamped on the deck housing). Not for 42-inch or 48-inch decks.

Key Things to Know

• Quality concerns: Mixed reviews—some report blades are balanced and cut well, others note they dull faster than OEM blades or arrive slightly bent. Inspect before installing.
• Installation: Straightforward with a socket wrench and blade removal tool. Torque bolts to 40–55 ft-lbs. Use thread locker if not using OEM bolts.
• Mulching vs. bagging: These are mulching blades—they will not perform well for bagging or side-discharge. If you switch between modes, consider a dedicated set.
• Price vs. OEM: At ~$78 for three, they are about 30–50% cheaper than John Deere genuine blades. You pay less, but may replace them sooner.

Should You Buy It

Buy if you need a budget-friendly mulching blade set for a 54-inch John Deere deck and don’t mind potentially shorter lifespan or occasional quality checks. Skip if you want guaranteed balance and durability for heavy-duty commercial use—stick with OEM or premium aftermarket (e.g., Oregon or Stens).
