Aeagle GX21380 Blades for John Deere G110 D170 E180 S180 190C LA150 LA175 54'' Deck Lawn Mower Tractor Replace GY20679 GY20684 GY20686, Medium Lift, 3 Pack, Black

What It Is

The Aeagle GX21380 is a set of three medium-lift black mower blades designed to replace OEM parts on John Deere tractors with a 54-inch deck. They are intended for cutting grass in residential and light commercial mowing, offering a balance between lift and discharge performance.

Fitment & Compatibility

Before buying, confirm your mower has a 54-inch deck and that your model is listed: G110, D170, E180, S180, 190C, LA150, LA175 (plus compatible models). These blades replace OEM numbers GY20679, GY20684, and GY20686. Measure your existing blade length (should be ~21 inches) and center hole size (must match your spindle). Check that the blade offset and thickness align with your deck’s requirements—medium lift may not suit mulching or bagging setups.

Key Things to Know

• Quality: Black coating resists rust, but steel thickness is standard—expect 0.2–0.25 inches. Not as durable as premium OEM blades for heavy use.
• Installation: Medium difficulty; you’ll need a socket wrench and torque wrench (aim for 70-90 ft-lbs). Ensure blades are oriented correctly (cutting edge forward).
• Gotchas: These are not universal—verify spindle hole shape (round vs. star). Some users report slight imbalance; check balance before mounting.
• Price vs. OEM: At $41.28 for three, they cost about half of OEM sets. Good value if you don’t need extreme durability.

Should You Buy It

Buy these if you own a compatible John Deere with a 54-inch deck and want a cost-effective replacement for regular residential mowing. They work well for standard grass cutting but may not hold up as long in rocky or heavy-duty conditions. Avoid if you need mulching blades or OEM-grade toughness.
