ILONPA 42" Mower Blades 3-Pack — Notched High-Lift Direct-Fit Replacements for Gravely & Ariens, Balanced

High-lift notched replacement mower blades engineered to restore cutting performance for 42" Gravely and Ariens zero-turn decks.

When your 42-inch lawn mower is leaving uneven cuts or struggling with clippings, swapping in a fresh set of blades is the fastest way to regain clean, consistent results. The ILONPA 3-pack includes three notched high-lift blades designed to fit a wide range of Gravely and Ariens Zoom zero-turn models; each blade matches the original mounting, profile and balanced weight to minimize vibration and maintain blade-to-deck clearance.

Which mower models and part numbers do these blades replace?

These blades are made to be compatible with many Gravely and Ariens Zoom zero-turn machines that use a 42-inch deck and the listed OEM part numbers. They are direct-fit replacements for original blades with the same center hole and mounting configuration.

• Fits Gravely models including 915148, 915150, 915170, 915178, 915180, 915192, 915196, 915212, 915214, 915232, 915234, 915246, 915328.

• Replaces part numbers 04265400 and 1134-9210-01 for 42" decks.

How are the blades sized and what are the key dimensions?

Each blade is manufactured to the exact proportions needed for proper clearance and lift in a 42" deck, so you can expect correct fitment and consistent airflow under the deck.

• Overall length: 14 4/5 inches (approx.).
• Cutting width: 2 1/4 inches; thickness: 0.197 inches.
• Center mounting hole diameter: 5/8 inch, matching OEM hubs.
• Sold as a set of three blades, enough for a complete 42" deck service.

What makes these blades different — notched high-lift features?

The notched high-lift profile improves the airflow into the deck, lifting grass for a cleaner cut and more effective discharge or mulching depending on deck setup. Notches reduce debris clogging and help maintain consistent lift at typical mowing speeds.

• High-lift design produces stronger suction for upright grass cutting.
• Notches near the hub reduce resistance and clear clippings more easily.
• Balanced construction lowers vibration and preserves spindle bearings.
• Edges are painted for rust protection during storage and installation.

Anything special I should know before installing?

The blades arrive painted along the cutting edge as a protective layer to prevent corrosion and to reduce the risk of scratches during handling. That paint is temporary and will wear off quickly after the first few minutes of mowing—do not scrape it off prior to use.

• Painted edges protect against rust and reduce installer risk; it will wear off with initial use.
• Verify center hole size and blade orientation during installation for safe operation.
• Balanced as a set—replace all three blades together to maintain even cutting and reduce vibration.
• Keep the mounting hardware torque consistent with your mower manufacturer’s spec.

Who is this for: Owners, fleet managers and landscapers with Gravely or Ariens zero-turn mowers that use a 42" deck and those looking for a cost-effective, OEM-compatible blade replacement. This ILONPA 3-pack is ideal if you need a full set to restore cutting performance, reduce vibration, and maintain airflow under the deck without adapting or modifying original mounting points.
