John Deere Original Equipment 3 Mower Blades #M115495(3)

What It Is

This is a set of three OEM replacement blades for John Deere mowers, designed for mulching, bagging, or side-discharge cutting. Each blade is 20.5 inches long, fits 54-inch and 60-inch decks, and is made for residential or light commercial use.

Fitment & Compatibility

Before buying, verify your deck model and blade measurements. These blades fit John Deere decks with 20.5-inch blades, including 54-inch (e.g., X500 series, X700 series) and 60-inch decks (e.g., Z900 series, 1000 series). Check your current blade length, center hole diameter (typically 1 inch), and thickness (0.203 inches). This is an OEM part, not aftermarket, so it matches factory specs. Confirm your mower’s part number cross-references to M115495—common on models like X570, Z535M, and 1025R. Avoid if your deck uses 21-inch or shorter blades.

Key Things to Buy

• Quality: OEM blades are heat-treated and balanced for durability; aftermarket blades may dull faster or cause vibration.
• Installation: Easy with basic tools—use a socket wrench and torque to 55-70 ft-lbs. Wear gloves to avoid cuts.
• Gotchas: Always replace all three blades as a set to maintain balance. Check spindle bearings for wear before installing new blades.
• Lift: These are high-lift blades, ideal for bagging but may blow grass clippings on sidewalks if side-discharging.

Should You Buy It

Buy this if you own a compatible John Deere mower and want OEM reliability, consistent cut quality, and exact fit without measuring aftermarket variations. It’s best for users who mow weekly and prioritize longevity over saving a few dollars on generic blades.
