Oregon Gator G3 Mulching Mower Blades, 3-Pack 18-7/16" for 54" Decks — High-Lift, Hardened Edge

Oregon Gator G3 mulching blades — a three-pack of heavy-duty 18-7/16" replacement mower blades engineered for clean mulching, strong side discharge, and long-lasting service on many residential and commercial mowers.

These Gator G3 blades are manufactured in the USA with a 26-point quality checklist and a reinforced cutting edge designed to resist bending and breakage in normal and abrasive turf conditions. They deliver a high-lift angle for improved airflow, finer grass clipping mulching and efficient side discharge. Each pack includes three identical blades sized to fit many 54-inch deck applications and common OEM models.

Will these blades fit my mower model?

The Oregon G3 blades use an 18-7/16" overall length, 0.187" thickness, a 2.5" width and a 5-point star center hole adapter, a common configuration on many brands. They are designed to replace numerous OEM part numbers and are compatible with a broad list of walk-behind and riding mowers.

• Exact length: 18-4/9" (18-7/16") and thickness 0.187"
• Center mounting: 5-point star hole for many decks
• Common fit: Works with Ariens, AYP/Husqvarna, Craftsman, Dixon, Murray, Poulan, Rotary, Stens and others
• Check your deck bolt pattern and blade length to confirm fit before installation

How do Gator G3 blades improve cutting and mulching?

Gator G3 blades feature Oregon’s proprietary Gator Mulcher geometry that increases the blade’s lift and airflow to recirculate clippings and produce finer mulch. That design reduces large clumps and improves side discharge performance without altering your mower’s standard operation.

• High-lift angle increases airflow for cleaner cut and discharge
• Sharpened, heavy-duty edge resists wear in abrasive conditions
• Mulcher geometry promotes smaller clippings for faster decomposition
• Suitable for wet, dry or sandy turf when used as directed

What are the materials and durability features?

Oregon manufactures these blades to a 26-point quality standard that emphasizes material strength, heat treatment and consistent edge geometry. The construction helps prevent bending and failure under typical lawn mowing stresses.

• Made in the USA with hardened cutting edge treatment
• Heavy-duty steel construction rated for residential and commercial use
• Resists bending and breaking in normal and abrasive conditions
• Each pack includes three blades to replace a full mower set on many decks

How do I match these blades to OEM part numbers?

Oregon lists many compatible OEM replacements and cross-references to help identify the correct blade. Compare your current blade’s part number, length and center hole style to the specs provided to confirm compatibility.

• Replaces common numbers: Ariens 21546235, Craftsman 187255/187256, many AYP/Husqvarna variants
• Also cross-references: Dixon 532187756, Murray 187256, Poulan 187254/187255, Rotary 12121, Stens 302-430
• If unsure, remove an existing blade and compare exact dimensions before ordering
• Ideal when replacing a matching three-blade set on 54" decks

Who is this for: The Oregon Gator G3 3-pack is for homeowners and landscape professionals who want a durable, OEM-compatible replacement blade set that improves mulching, maintains side discharge performance and withstands tougher mowing conditions. Choose these blades if you need three matched blades for a 54" (approximately) deck, want American-made manufacturing standards, and require broad compatibility with brands such as Ariens, Husqvarna/AYP, Craftsman, Dixon, Murray and Poulan.
