John Deere Original Equipment 3 Mower Blades #M152726(3)

What It Is

These are three OEM replacement blades for John Deere riding mowers and zero-turn models, designed for mulching, bagging, or side-discharge cutting. The M152726(3) set is a direct factory replacement for 42-inch and 48-inch decks.

Fitment & Compatibility

• Check your deck size: This blade set fits John Deere 42-inch (e.g., D100 series, X300 series) and 48-inch decks (e.g., X500 series, Z500 series). Measure your blade length—these are 16.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.25-inch offset.
• Confirm model number: Use John Deere’s online parts lookup or your owner’s manual to verify M152726 is listed for your mower. Common compatible models include D105, D110, D125, D130, X304, X320, X350, X360, Z425, Z445, Z535M, and Z545R.
• OEM vs aftermarket: These are genuine John Deere parts, so fit and balance are guaranteed. Aftermarket alternatives are cheaper but may require balancing and have shorter life. Double-check if your deck uses a different blade part number for mulch kits.
• Measure your old blade: If your deck has been modified or you’re unsure, remove one blade and compare length, width, hole size, and offset angle. A mismatch can cause vibration or poor cut.

Key Things to Buy

• Quality: Made from heat-treated steel for durability and edge retention. They’re pre-balanced from the factory, so no extra balancing needed.
• Installation difficulty: Moderate—requires a socket wrench and torque wrench. Use a blade removal tool or block the blade with wood to prevent spinning. Torque bolts to 40-50 ft-lbs (check your manual).
• Common gotchas: Always replace all three blades at once for even wear and balance. Install with the cutting edge facing the direction of rotation (usually upward on the blade tip). Don’t reuse old bolts—buy new ones (#M8060 or similar) to prevent stripping.
• Lift vs mulch: These blades have moderate lift for general cutting. If you primarily mulch, consider dedicated mulch blades (e.g., John Deere #M152727) for better clippings recirculation.

Should You Buy It

If you own a compatible John Deere 42- or 48-inch deck and want reliable, factory-fit blades with no guesswork, this set is a solid choice. It’s ideal for homeowners who value longevity and consistent cut quality over aftermarket savings. For heavy mulching or high-volume commercial use, consider a dedicated mulch blade instead.
