John Deere Original Equipment 3 Mower Blades #M164016

What It Is

This is a set of three OEM (Original Equipment) mower blades designed specifically for John Deere Z‑Track and certain select‑series lawn tractors. They are built for cutting grass on residential or commercial‑size properties, not for heavy brush or rough terrain.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: These blades fit only 48‑inch and 54‑inch cutting decks on compatible John Deere models (e.g., Z225, Z235, Z245, Z425, Z445, Z465, X304, X320, X324, X340, X360, X380, X384, X394). Check your deck’s serial number plate.
• OEM vs aftermarket: This is a genuine John Deere part (not a generic replacement). It will match the factory blade hole pattern, thickness, and lift exactly. Aftermarket blades may require modifications or cause vibration.
• Measurements: Each blade is 17.25 inches long, 2.5 inches wide, with a 0.25‑inch center hole and a 1‑inch offset. Measure your old blade to confirm these dimensions.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a torque wrench and a blade removal tool. Torque center bolt to 70‑80 ft‑lbs. Left‑hand thread? No—all are standard right‑hand.
• Sharpening vs replacement: These are not designed for repeated sharpening. Once they’re dull, chipped, or bent, replace them as a set for balanced cutting.
• Common gotcha: The blades must be installed with the lift wings pointing up toward the deck. Reversing them will cause poor cut and dangerous vibration.
• Quality: Heat‑treated steel with a protective coating resists rust better than most aftermarket options. Balanced out of the box—no filing needed.

Should You Buy It

Buy this set if you own a compatible John Deere Z‑Track or select‑series tractor with a 48‑ or 54‑inch deck and want a guaranteed fit, factory‑spec balance, and longer edge life. It’s the right choice for anyone who values consistent cut quality and doesn’t want to gamble on aftermarket blades that might not match. Skip it if you have a different deck size or brand—then look for a model‑specific OEM set instead.
