What It Is

This is a 3-pack of high-lift mower blades designed for 48-inch John Deere lawn tractors. The high-lift profile creates stronger airflow for improved grass clipping discharge and bagging performance, making it ideal for thick or tall grass.

Fitment & Compatibility

• Deck size: Designed for 48-inch cutting decks only. Measure your deck before ordering.
• Model fit: Fits John Deere D140, D160, E140, E160, E150, E170, LA145, LA140, plus select D100/E100 series with a 48-inch deck. Not for 42-inch or 54-inch decks.
• OEM cross-reference: Replaces AM141035, GX21786, and GX20852. Also fits part numbers GY20852 and GX21784.
• Star pattern: 7-point star center hole. Confirm your spindle uses a 7-point star pattern (common on late-model Deere 48-inch decks). Early models may use a 5-point star—check your old blade.
• Measurements: Blade length approximately 20.5 inches. Verify your existing blade length before purchase.

Key Things to Know

• High lift vs. standard: These blades generate more suction, which improves bagging and side discharge but increases engine load and noise. Not ideal for mulching.
• Installation: Moderate difficulty. You’ll need a socket wrench and a blade removal tool or block of wood to prevent spindle rotation. Torque bolts to 70-90 ft-lbs.
• Balance check: Aftermarket blades may need balancing out of the box. Use a blade balancer to avoid vibration that can damage the spindle or deck.
• Durability: A few reviews note these blades dull faster than OEM Deere blades, especially in sandy soil. Check sharpness every 10-15 hours of mowing.

Should You Buy It

Buy this set if you need a budget-friendly replacement for a 48-inch John Deere deck with a 7-point star pattern and you primarily bag or side-discharge thick grass. Skip it if you mulch heavily, need OEM-level longevity, or have a 5-point star spindle. At $26.98 for three blades, it’s a solid value for average home use.
