ILONPA 54" Medium‑Lift Replacement Blades for John Deere 54" Decks — M143520/UC22010, 2‑in‑1 Medium Lift, Painted Edges

ILONPA M143520 54" medium‑lift replacement blades are a direct-fit set for John Deere 54" decks, engineered to restore clean, even cuts on Zero‑Turn and lawn tractors.

These 54‑inch replacement blades (M143520 / UC22010) are built to match the geometry and mounting of many John Deere ZTRAK, EZtrak and compact tractor models. They use a 2‑in‑1 medium‑lift profile that creates airflow to lift grass slightly before shearing, producing a neater discharge and consistent finish across residential and light commercial lawns. The cutting edges arrive painted for installer safety and will wear off quickly during normal use.

How do these medium‑lift blades affect cut quality?

The medium‑lift (standard) contour provides a balance of airflow and cut power, raising grass into the knife path for a more uniform trim. They are a practical choice for lawns with fine to medium grass where a tidy discharge and even stripe are desired.

• Medium lift profile slightly elevates grass for a cleaner shear
• 2‑in‑1 design balances bagging and side discharge performance
• Painted edges protect installer hands and wear off during first use

What are the exact blade dimensions and mounting details?

These blades are manufactured to precise dimensions to match OEM fitment and maintain deck geometry. Check these measurements against your current blade and spindle specs when replacing.

• Overall blade length: 19.0" (483 mm)
• Cutting edge width: 2-2/3" (68 mm); thickness: 0.2" (5 mm)
• Center hole: circular, 0.812" (20.6 mm); air lift height: 1.375" (35 mm)
• Type: 2‑in‑1 medium lift, compatible with 54" decks

Are there any installation or safety notes I should know?

The cutting edges are coated with paint to reduce the risk of accidental cuts during handling. This protective coating is intentional and will abrade off quickly during the first mowing passes; do not attempt to scrape it off before installation.

• Edges are painted for installer safety—paint will wear off with initial use
• Always disconnect spark plug and follow mower manufacturer torque specs when installing
• Inspect blades for balance and tightness after the first mow
