Aeagle 54" Medium-Lift Mower Blades for John Deere G110 D170 S180 – 3-Pack Blue, 18-5/8"

Aeagle GX21380 54" medium-lift mower blades are a three-pack replacement set engineered to fit John Deere 54-inch decks (models like G110, D170, E180, S180, 190C, LA150, LA175) and deliver reliable cutting, discharge, and bagging performance.

These replacement blades are designed to match John Deere part numbers GY20679, GY20684, and GY20686 while offering a medium-lift profile that balances grass lift and discharge. Each blade measures 18 5/8" long, 2 2/3" wide, and 1/5" thick with a 7-point star center hole to fit standard 54" mower spindles. Finished in blue safety paint at the cutting edge, the blades arrive ready for installation and can be resharpened when worn.

How do these medium-lift blades perform on different grass conditions?

The medium-lift profile offers a compromise between high-lift and low-lift designs, pulling grass upright for a cleaner cut while still allowing efficient side discharge. They work well for routine mowing, light bagging, and handling slightly taller or damper grass without overloading the deck's airflow.

• Creates enough suction for tidy bagging and neat clippings
• Suitable for regular lawns and occasional tall or wet grass
• Balances airflow to reduce clogging compared with high-lift blades
• 2-in-1 capability: discharges and bags in a single blade profile

Are these blades durable and maintainable?

Aeagle blades are built with stamped steel and a protective paint finish to resist corrosion and protect the cutting edge during shipping and storage. The safety paint on the edge will wear as you use them; the blades are purposely serviceable and can be resharpened to extend useful life.

• Stamped steel construction for strength and impact resistance
• Safety paint on cutting edge that wears off during use
• Can be safely resharpened when edges dull to restore cutting performance
• Pack of three blades provides a full deck set for most 54" tractors

What should I check before installation?

Before fitting the blades, confirm deck and spindle compatibility, use correct mounting hardware torque, and inspect for debris or damage on the spindle and blade mounting surfaces. Replace blades in matched sets to maintain deck balance and avoid vibration.

• Verify 7-point star center hole aligns with your spindle
• Ensure deck and spindle are clean and undamaged
• Tighten blade bolts to manufacturer torque specs and use threadlocker as recommended
• Install all three blades together for balance on a 54" deck

Who is this for: The Aeagle GX21380 3-pack is aimed at homeowners and small-property managers who own a John Deere 54" lawn tractor and want an affordable, ready-to-install replacement that balances bagging and discharge. Choose these blades if you need a reliable medium-lift option for regular mowing, occasional tall or damp grass, and prefer parts that can be resharpened for extended service life.
