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, Blue

What It Is

The Aeagle GX21380 is a set of three medium-lift mower blades designed to replace OEM blades on John Deere 54-inch deck tractors. They are suited for mulching, bagging, or side-discharge cutting on residential lawns and light commercial use.

Fitment & Compatibility

• Deck size: Only fits John Deere 54-inch cutting decks (not 42", 48", or 60").
• Compatible models: G110, D170, E180, S180, 190C, LA150, LA175 – verify your model’s deck size before ordering.
• OEM replacements: Replaces GY20679, GY20684, GY20686.
• Measurements: Blade length is 21 inches, center hole diameter is 1 inch, with a 0.25-inch thick steel. Measure your existing blade to confirm length and hole size.
• Aftermarket note: These are not genuine John Deere parts. Fitment is standard for the listed models, but double-check blade alignment and spindle clearance after installation.

Key Things to Know

• Medium lift design – balances cutting performance with reduced engine load; works well for regular grass but may clog in wet, thick growth.
• Installation difficulty – easy with a socket wrench and blade removal tool; torque to 70–90 ft-lbs per John Deere specs.
• Common gotcha – the blue coating is cosmetic and wears off quickly; inspect blades for sharpness after 10–15 hours of use.
• Quality note – heat-treated steel holds an edge decently but may dull faster than OEM blades on rocky or sandy soil.

Should You Buy It

If you own a compatible John Deere with a 54-inch deck and want a budget-friendly, reliable replacement for regular mowing, this three-pack delivers solid value. Skip it if you need heavy-duty blades for rough terrain or long intervals between sharpening.
