ILONPA 42-inch High-Lift 7-Point Star Mower Blades — 2-Pack for John Deere 42" Decks, Improved Bagging & Clean Cut

These ILONPA AM141034 high-lift mower blades are a 2-pack of 42-inch, 7-point star replacement blades engineered for John Deere 42" decks to restore cut quality, boost bagging performance, and reduce clumping.

When your John Deere lawn tractor or zero-turn starts leaving uneven clippings or struggles to fill a bag, worn blades are often the cause. The ILONPA AM141034 set fits many John Deere 42" mowing decks and related models, offering high-lift geometry that increases airflow for cleaner cuts and improved material discharge. Each blade uses a 7-point star center hole and standard dimensions so installation is straightforward for common residential and light-commercial tractors.

Which machines will these blades fit?

These replacement blades are designed around the 42" deck standard and match the 7-point star center mounting pattern found on many John Deere mowers. They are compatible with a wide list of tractors, zero-turns, and riding mowers, including popular D, LA, LT, X, and Z series machines and some Sabre/Europro decks.

• Fits John Deere 42" decks with 7-point (7-star) center hole, 7/8" (22.2mm) bore.
• Commonly compatible models: D1xx, LA1xx, LT1xx, X3xx, Z225/Z235, and many X300 series variants.
• Also fits several residential zero-turn and Sabre/Europro models listed in the compatibility range.

How do high-lift blades change mowing performance?

High-lift blades are shaped to pull air upward under the deck, producing a strong suction that lifts grass before shearing. That improved airflow creates a cleaner, more even cut and moves clippings efficiently into the bagger or discharge chute. For yards where bagging, mulching, or a manicured finish matters, high-lift blades are a practical upgrade.

• Enhanced upward airflow for straighter grass blades before cutting.
• Better bagging and chute discharge—less clogging and thatch buildup.
• Sharper-looking lawn finish with fewer missed strands and less re-cutting.

What are the exact dimensions and mounting details?

Knowing the precise measurements helps you confirm fitment before purchase. Each ILONPA blade measures 21-1/4" end-to-end (approx. 540mm) and is sized for a 42" deck. The center uses the 7-star pattern with a 7/8" (22.2mm) center bore, and blade thickness and lift height follow common OEM-style specifications.

• Length: 21-1/4" (540mm); Width: 2-5/8" (66.5mm).
• Thickness: ~1/6" (4.5mm); center hole: 7-point star, 7/8" (22.2mm).
• Air lift height: approximately 1-3/7" (36mm); type: high-lift blade.

Are these blades ready to install and how are they protected?

ILONPA ships this two-piece blade set ready for installation; the cutting edges are temporarily painted to prevent rust and reduce risk during handling. That protective coating will wear off after a short period of normal mowing and should not be removed by solvents. Use proper torque on spindle bolts and follow the mower manufacturer’s safety guidelines when replacing blades.

• Comes as a 2-pack for full deck replacement or spare blade on hand.
• Cutting edges factory-painted to inhibit surface corrosion and protect installers.
• Standard DIY replacement—use manufacturer torque and safety practices.

Who is this for? Homeowners and landscapers with John Deere 42" mowing decks who want to restore cutting performance, improve bagging results, or upgrade to high-lift airflow will benefit from this ILONPA blade set. It’s well suited for routine blade replacement on residential tractors and light commercial machines that accept the 7-star mounting pattern.
