What It Is

A 2-pack of aftermarket 42-inch deck mower blades from maXpeedingrods, designed to replace OEM blades on a wide range of John Deere lawn tractors. Suitable for standard residential cutting and mulching on 42" decks.

Fitment & Compatibility

• Deck size: 42-inch (not 48" or 54"). Measure your deck underside to confirm.
• Models: Fits John Deere 100/100D/100LA/LA100-LA135/X105-X310/E100-E130/S110-S240 series (e.g., D100, D110, D125, D130, X105, E100, S110). Also fits older 102/105 models.
• OEM replacements: Replaces John Deere part numbers UC21583, GY20850, AM141033, AM137333. Check your current blade’s part number stamped on it.
• Measurements: Blade length ~21.5 inches, center hole diameter ~1 inch, thickness ~0.25 inches. Verify these match your existing blade before ordering.

Key Things to Know

• Quality: Budget aftermarket steel—adequate for residential use but may dull faster than OEM blades. Not for heavy commercial cutting.
• Installation: Direct bolt-on if your deck uses a single center bolt (5/8" or 1/2" socket). No adapters needed. Torque to 50-70 ft-lbs.
• Common gotcha: The blades are not universal—only fit 42" John Deere decks. Check deck model tag under the seat or frame. Aftermarket blades may not balance perfectly out of the box; test spin before full install.
• Edge sharpness: Typically come sharp enough for grass, but edge quality varies. Light honing may improve cut.

Should You Buy It

If you need a quick, low-cost replacement for a 42" John Deere deck and don’t mind replacing blades more often than OEM, this is a solid budget pick. Avoid if you have a different deck size or need commercial-grade durability.
