What It Is

The ACEBRI High Lift Blades 42’’ are a 2-pack of aftermarket replacement blades designed for 42-inch cutting decks on select John Deere lawn tractors. They feature a high-lift profile to increase airflow for better grass clipping discharge and bagging performance, making them ideal for mulching or side-discharge use in thick or tall grass.

Fitment & Compatibility

Before buying, verify your John Deere model has a 42-inch deck (measure from blade tip to tip). These blades replace OEM part numbers AM141034, AM137329, and M154062. They fit models including the 100-series (105, 115, 125, 135), D100 series (D100, D105, D110, D120, D125, D130), LA series (LA115, LA120, LA125, LA135), LT160, LT180, SST15, and SST16. Double-check your deck’s center hole diameter (should be 7/8-inch or 22mm) and blade length (measure from center hole to tip; must be 21 inches total). If your deck uses a different blade mount pattern or length, these won’t work.

Key Things to Know

• Quality vs OEM: ACEBRI blades are aftermarket, typically thinner steel than John Deere OEM (original equipment manufacturer) blades. They may wear faster but cost significantly less.
• Installation: Standard—remove deck, secure blade with a block of wood, and use a wrench. Torque the center bolt to 70-90 ft-lbs (check your manual). No special tools required.
• Common Gotcha: High-lift blades increase suction, which can strain the engine or belt if the deck is clogged with wet grass. Keep the underside clean to avoid bogging down.
• Balance: Always check blade balance after installation; unbalance causes vibration and uneven cut. Use a simple blade balancer (under $10).

Should You Buy It

If you need a budget-friendly replacement for your 42-inch John Deere deck and primarily cut dry, tall grass or want better bagging, these are a solid value. They’re not ideal for heavy-duty commercial use or wet mowing conditions where OEM durability matters more. For residential use with moderate cutting, the price and performance are hard to beat.
