John Deere OEM 2Pk Mower Blade Kit LT 160 X 300 R 304 324 D 105 125 Z 225 AM140973

What It Is

This is an OEM 2-pack of replacement mower blades (AM140973) designed for John Deere lawn tractors and zero-turn mowers. It fits select 100, 200, and 300 Series models with 42-inch or 48-inch cutting decks, including the LT160, X300, X304, X324, D105, D125, and Z225.

Fitment & Compatibility

• Deck size: Confirms to 42-inch (e.g., LT160, D105) or 48-inch (e.g., X300, X304, Z225) decks. Measure your deck width from side to side under the mower.
• Model check: Use John Deere’s official parts lookup (johndeere.com) with your model and serial number. This kit replaces OEM part AM140973, AM103029, AM103030, or AM137342.
• OEM vs. aftermarket: OEM ensures exact hole pattern, blade length (approx. 16.5 inches), and thickness. Aftermarket blades may not match the offset or lift angle.
• Measurements: Blade length is 16.5 inches, center hole is 1 inch, and blade thickness is 0.20 inches. Verify your existing blade matches these specs.

Key Things to Know

• Quality: OEM blades are heat-treated steel with a hardened edge for longer life and consistent cut. They resist bending better than cheap aftermarket sets.
• Installation difficulty: Easy—requires a 15/16-inch or 1-inch socket, a torque wrench (set to 70-90 ft-lbs), and lifting the mower safely. Use a block of wood to keep the blade from spinning.
• Common gotchas: Blades are directional—install with lift wings pointing up toward the deck. Mixing up left/right on 48-inch decks can cause vibration. Always replace bolts (recommended) to prevent stripping.
• Price note: At $118.82, this is premium OEM pricing. You’re paying for exact fit and durability, not a bargain.

Should You Buy It

Buy this if you own a listed John Deere model and want a guaranteed fit, consistent cut quality, and longer blade life without guesswork. It’s ideal for owners who prioritize reliability over cost savings. If you’re on a tight budget or have a less common deck size, consider an aftermarket set—but verify compatibility carefully.
