ILONPA 42" Notched High-Lift Mower Blades 3-Pack — 42in OEM-Style Replacement, Rust-Resistant Edges

If your 42" zero-turn deck needs fresh cutting edges, this ILONPA 3-pack gives you full-coverage replacement blades sized and punched to match popular Gravely and Ariens models. Each blade is designed for high-lift airflow to improve grass lift and bagging performance, and comes factory-painted on the edges to reduce surface rust and protect installers during handling. The set replaces part numbers 04265400 and 1134-9210-01, so it’s a simple swap for many standard 42" mower spindles.

Which mowers will these blades fit?

These blades are made for 42" decks used on specific Gravely and Ariens zero-turn and Zoom models. They match the 5/8" center hole and the length, width and thickness used on many OEM blades so bolt-on installation is straightforward when the deck uses the listed patterns.

• Gravely models covered include multiple 9151xx and 9152xx ZT 42 frames.
• Ariens Zoom/Zero-Turn models listed such as 915159, 915161 and 915323.
• Replaces OEM numbers 04265400 and 1134-9210-01 for 42" decks.
• Confirm your deck uses a 5/8" center hole and similar blade dimensions before purchase.

How do these notched high-lift blades affect cutting performance?

Notched high-lift blades create more upward airflow beneath the deck, which helps lift grass for a cleaner cut and improves material discharge or bagging. The notches reduce weight and can help prevent clogging in heavier turf, while the high-lift shape boosts suction for even clippings distribution.

• High-lift profile enhances grass stand-up for a uniform cut.
• Notches reduce drag and minimize clogging in dense lawns.
• Better suction improves bagging and side-discharge efficiency.
• Painted edges reduce rust and protect installers prior to break-in.

What are the exact specifications and how do I install them?

Each blade measures roughly 14 4/5" long, 2 1/4" wide and 0.197" thick with a 5/8" center bore. The set includes three identical blades—enough for a typical 42" three-blade deck. Installation follows standard blade replacement steps: secure the mower, remove old blades, align the center hole and bolt, torque to manufacturer specs, and check clearance before use.

• Length: 14.8" | Width: 2.25" | Thickness: 0.197".
• Center hole diameter: 5/8" to match common spindle shafts.
• Package contains three blades for a full 42" deck replacement.
• Always use correct bolt torque and safety procedures during install.

Is there anything special I should know about the paint on the cutting edge?

The cutting edges are coated with protective paint to help prevent surface rust and to soften handling risk during installation. That coating is intentional and will wear away quickly once the blades start cutting; do not scrape it off before first use. This finish protects the blade during storage and transport and reduces the chance of accidental scratches during handling.

• Painted cutting edges guard against corrosion during storage.
• The paint also reduces sharpness-related handling injuries before install.
• Expect the coating to wear off naturally after initial mowing passes.
• Do not forcefully remove the paint; it’s part of the product design.

Who is this for: This ILONPA 3-pack is intended for owners and technicians of Gravely and Ariens 42" zero-turn or Zoom decks who need a direct-fit, cost-effective blade replacement. It’s a strong choice for homeowners maintaining lawn appearance, landscapers who swap blades frequently, and fleet operators seeking consistent OEM-style dimensions without the premium OEM price—so long as your mower matches the listed models and spindle specifications.
