AM141034 42 inch 7-Star Blades for John Deere D130 D105 D110 D125 LA135 LA105 X300 Z225 Z235 LT160 LT180 42" Deck Lawn Tractor and Garden Replace JD AM137329 M154062 AM141037 (High Lift) 2-Pack, Black

What It Is

This is a 2-pack of 42-inch, 7-star high-lift blades designed to replace OEM John Deere blades on select lawn tractors and garden tractors with 42-inch decks. They are meant for heavy-duty cutting, mulching, and bagging, especially in thick or tall grass.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck—not 38, 48, or 54 inches. This set fits John Deere models D130, D105, D110, D125, LA135, LA105, X300, Z225, Z235, LT160, and LT180. It directly replaces OEM part numbers AM137329, M154062, and AM141037. Measure your blade length (42 inches end to end) and center hole diameter (typically 1 inch). Check that your deck spindle pattern matches—these use a star-shaped center hole (7-point) and three mounting holes. If your current blades are oval or have a different hole pattern, these won’t fit.

Key Things to Know

• High-lift design: These blades create strong airflow for bagging and mulching, but they increase engine load and can cause more wear on belts and spindles. Not ideal for dry, dusty conditions.
• Installation: Moderate difficulty. You’ll need a socket wrench, torque wrench (recommended 70-90 ft-lbs), and safety blocks. Always disconnect the spark plug and remove the battery before working.
• Common gotcha: The 7-star center hole is specific to John Deere and some aftermarket decks. Verify your deck uses a star pattern, not a round or oval hole. If your OEM blades are 3-hole round, these won’t work.
• Balance check: Aftermarket blades may not be as precisely balanced as OEM. Use a blade balancer before installing to avoid vibration and spindle damage.

Should You Buy It

If you own a compatible John Deere with a 42-inch deck and need high-lift blades for aggressive bagging or mulching in thick grass, this is a solid, well-rated option at a good price. Skip it if your deck uses a different hole pattern, or if you primarily cut dry, light grass where standard lift blades would be more efficient.
