2PK USA Mower Blade for 46" Ariens 21546611 AYP 532405380 Husqvarna 532403107

What It Is

This is a 2-pack of universal replacement mower blades designed for 46-inch cutting decks, compatible with Ariens, AYP, and Husqvarna models. They’re ideal for medium-to-large residential lawns and general grass cutting, not heavy-duty mulching or bagging.

Fitment & Compatibility

• Deck size: Fits 46-inch (117 cm) mower decks.
• OEM cross-references: Ariens 21546611, AYP 532405380, Husqvarna 532403107.
• Measurements: 22.25 inches long, 2.75 inches wide, with a 1-inch center hole and 0.25-inch offset. Verify these against your current blade before buying.
• Brand fit: Works on many Ariens, AYP, Husqvarna, Craftsman, and Poulan Pro models with 46-inch decks. Check your mower’s manual or remove a blade to confirm hole pattern and offset.
• Aftermarket note: Not OEM, but matches OEM specs for direct replacement. Avoid using on decks smaller or larger than 46 inches.

Key Things to Know

• Quality: Heat-treated steel with a protective coating; rated for standard grass, not thick brush or debris.
• Installation: Easy—use a socket wrench and blade removal tool. Torque bolts to 70-90 ft-lbs. No special adapters needed.
• Common gotcha: These are not mulching blades. If you need finer clippings, look for a mulching set. Also, check if your deck uses a different hole pattern (e.g., oval or star) before buying.
• Pack: 2 blades included—enough for a single 46-inch deck change. Keep one as a spare if you rotate blades.

Should You Buy It

Yes, if you have a 46-inch deck from Ariens, AYP, Husqvarna, or compatible models and need a reliable, affordable replacement for standard grass cutting. Skip if you require mulching blades or have a non-standard hole pattern.
