What It Is

This is a 2-pack of high-lift replacement blades designed for 38-inch cutting decks on John Deere lawn tractors. The high-lift profile increases airflow under the deck for superior grass clipping discharge and bagging performance, making it ideal for taller or damp grass.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 38 inches. This blade fits John Deere models including X300, 116H, 1538H, LX172, LX176, LT150, STX38, and GT242. It directly replaces OEM part numbers AM141039, AM100945, AM141041, AM100991, M153118, and M154159. Measure your existing blade’s length (approximately 18-5/8 inches), center hole diameter (about 7/8 inch), and thickness (0.25 inch). The blade is aftermarket, not OEM John Deere, but designed to match OEM specs. Check that your deck’s spindle assembly is not bent or worn before installation.

Key Things to Know

• Installation difficulty: Easy – requires a socket wrench and torque wrench (recommended torque: 70-90 ft-lbs). Always use thread-locking compound on blade bolts.
• Lift performance: High-lift blades create more suction, improving bagging and side discharge, but may increase engine load slightly. Not ideal for mulching unless you swap to a mulching blade.
• Build quality: Made from heat-treated steel with a blue powder-coat finish for corrosion resistance. Some users report they are slightly thinner than OEM blades, but still durable for residential use.
• Common gotcha: Ensure you install with the curved edge facing upward toward the deck, not downward. Also, check that blade bolts are not stripped or damaged before reusing.

Should You Buy It

If you own a compatible John Deere with a 38-inch deck and want better clipping discharge or bagging performance without paying OEM prices, this 2-pack is a solid value. Avoid it if you prefer mulching or need exact OEM thickness for heavy commercial use.
