8TEN LawnRAZOR Blade Set for John Deere 38 inch Deck 240 GT242 LT150 AM137324 AM141039 M153118 M84472 (High Lift)

What It Is

This is a set of three high-lift replacement blades designed for John Deere 38-inch cutting decks, commonly found on 200-series lawn tractors. The high-lift design improves grass discharge and bagging performance, making it ideal for thick or tall grass.

Fitment & Compatibility

Before buying, confirm your deck is exactly 38 inches wide (measure cutting swath, not deck housing). Compatible with John Deere models like 240, GT242, LT150, and others using OEM part numbers AM137324, AM141039, M153118, or M84472. These are aftermarket blades, not OEM John Deere. Check blade length (approx. 21 inches), center hole diameter (usually 7/8 inch), and offset (should match your old blade). Verify your spindle pattern—most 38-inch decks use three blades, but some have two. If your deck is a 42-inch or 48-inch, these won’t fit.

Key Things to Know

• Installation: Straightforward with basic tools (socket wrench, torque wrench). No special adapters needed, but ensure blades are mounted with cutting edge facing upward.
• Lift difference: High-lift blades create more airflow and suction than standard blades—great for bagging, but can reduce engine power on low-horsepower tractors and throw more debris.
• Balance check: Aftermarket blades sometimes need balancing. Spin-test on a balancer before installing to avoid vibration that can damage spindles.
• Durability: Users report good edge retention and rust resistance, but these are not hardened steel like premium OEM blades—expect slightly shorter lifespan in abrasive conditions.

Should You Buy It

Buy these if you need reliable high-lift blades for a John Deere 38-inch deck and want to improve bagging or discharge without paying OEM prices. Skip them if you have a different deck size, need mulching blades, or prefer the exact fit and longer life of genuine John Deere parts.
