What It Is

This is a 2-pack of ACEBRI 38-inch replacement mower blades designed for John Deere lawn tractors with a 38-inch cutting deck. They are intended for residential mowing on standard turf and grass.

Fitment & Compatibility

Before buying, confirm your John Deere deck is exactly 38 inches (measured blade tip to tip). These blades fit models: LT150, LT155, LT160, LX172, LX173, LX176, LX178, STX38, and GT242. They replace OEM part numbers AM100945, AM100991, AM137324, AM141039, and AM141041. Measure your existing blade length (38 inches), center hole diameter (typically 5/8 inch), and thickness (approx. 0.1875 inch). Also check blade offset—these are likely a low-lift or standard lift design, so verify your deck’s blade type (mulching, bagging, or standard discharge) to ensure proper grass flow.

Key Things to Know

• Quality: Made from heat-treated steel with a painted finish; expect decent durability for residential use but not commercial-grade hardness.
• Installation: Easy swap if you have a socket wrench and block of wood to prevent blade spin. Torque bolts to 70-90 ft-lbs. Mark blade orientation before removal.
• Gotchas: These are “standard” blades—not mulching or high-lift. If your deck requires a specific blade profile (e.g., for bagging), check that the ACEBRI design matches your OEM blade’s curve and air lift.
• Balance: Out of the box, they may need balancing. Use a blade balancer or hang on a nail to check; file the heavy side if needed.

Should You Buy It

If you own a John Deere with a 38-inch deck listed above and need a budget-friendly replacement for standard mowing, this 2-pack offers good value. However, if you require mulching blades or have a deck that demands high-lift airflow (e.g., for wet grass), look for a specific design.
