John Deere Original Equipment Mower Blades - UC22008,2

What It Is

These are John Deere original equipment (OEM) mower blades (part number UC22008, 2-pack) designed for 42-inch and 48-inch Edge, EZtrak, and Ztrak zero-turn mowers, as well as select X-series lawn tractors. They are for mulching, side-discharge, or bagging on residential and light commercial turf.

Fitment & Compatibility

• Deck size: Fits 42-inch and 48-inch decks only—check your deck’s stamped model number (e.g., 42C, 48C).
• Machine compatibility: John Deere Z225, Z235, Z245, Z425, Z435, Z445, Z645, Z655, Z725, X300, X304, X320, X324, X340, X344, X360, X364, X380, X384, and X394. Also Edge models EZtrak 42/48. Not for older 100-series or 7000-series tractors.
• OEM vs aftermarket: These are genuine John Deere, so no fitment guesswork—direct bolt-on for listed models. Aftermarket blades may have different hole patterns or thickness.
• Measurements before buying: Each blade is 20.5 inches long, 2.5 inches wide, with a 5-point star center hole (1.0-inch diameter) and 0.5-inch offset. Verify your current blade length and hole shape (star vs round). If your deck uses a different hole pattern, these won’t fit.

Key Things to Know

• Quality: OEM blades are heat-treated and balanced for less vibration and longer life than most aftermarket options. Expect 25–50 hours of cutting before dulling (depending on debris).
• Installation difficulty: Easy—requires a socket wrench and torque wrench (30–35 ft-lbs). Lift deck safely, remove bolts, replace blades, and re-torque. No special tools needed.
• Common gotcha: These blades are directional—the offset must face upward toward the deck. Installing upside down will cause poor cut and vibration.
• Pack contents: Two blades (covers one deck). If you have a 3-blade deck, you need a second pack (UC22008,2 is two per pack).

Should You Buy It

Buy these if you own a compatible John Deere zero-turn or X-series mower and want guaranteed fit, factory balance, and reliable cut quality. They’re the right choice for anyone who prefers OEM over aftermarket knockoffs—especially if you mulch or bag frequently. Skip them if you have a different brand deck or want cheaper alternatives (but expect shorter life and possible vibration).
