What It Is

This is a 2-pack of high-lift lawn mower blades from Terre, designed for 38-inch cutting decks on John Deere X300 and LX series tractors. High-lift blades create stronger airflow for superior grass clipping discharge and bagging performance, making them ideal for thick or damp grass.

Fitment & Compatibility

Critical checks before buying:

• Deck size: These blades are for 38-inch decks only. Measure your deck width or check your model number.
• Compatible John Deere models: X300, X304, X320, X324, X340, X360, LX172, LX173, LX176, LX178, LX186, LX188, LX255, LX266, LX277, LX279, LX280, LX288, and others with a 38-inch deck.
• OEM cross-references: AM137324, AM137326, AM100945, AM100991, AM141041, M84472, M83459, M153118.
• Blade measurements: Center hole is 1-inch diameter; overall length is approximately 19.5 inches; width is 2.5 inches. Verify your current blade matches these dimensions.
• Aftermarket note: This is a non-OEM replacement. Quality is generally good, but slight variations in thickness or balance can occur.

Key Things to Know

• Performance: High-lift blades increase suction, improving bagging and discharge but may require more engine power and can wear faster on sandy soil.
• Installation: Straightforward—remove the old blade, clean the spindle, and torque to manufacturer specs (typically 30–40 ft-lbs). Use a blade removal tool for safety.
• Gotcha: These blades are not for mulching. If you want to mulch leaves or grass, you need a dedicated mulching blade or kit.
• Balance: After installation, check blade balance by hanging it on a nail. An unbalanced blade causes vibration and uneven cut. Terre blades are usually balanced well, but verify.

Should You Buy It

If you own a John Deere X300 or LX series with a 38-inch deck and prioritize bagging or side-discharge performance over mulching, this is a solid, cost-effective choice. At ~$21 per blade, it’s cheaper than OEM and rated well by users. Avoid if you need mulching blades or have a different deck size.
