What It Is

This is a 2-pack of high-lift mower blades designed for 46-inch cutting decks on Husqvarna and Craftsman zero-turn and lawn tractors. The high-lift profile increases airflow under the deck, improving grass clipping discharge and bagging performance, especially in tall or damp grass.

Fitment & Compatibility

Deck size: 46 inches
OEM part numbers: 532405380, 405380 (Husqvarna) and 594892801 (Craftsman)
Fits these models: Husqvarna YTH22V46, Z246, YTH20K46, YTH21K46, YTH22K46, YTA22V46, RZ4623; Craftsman zero-turn models using a 46-inch deck.

What to check before buying:

• Measure your blade length (these are typically 20.5 inches center-to-center, but confirm with your current blade).
• Verify the center hole diameter (usually 1 inch) and the number of mounting holes (these use a single center hole with a pin or keyed slot).
• Check your mower’s deck model number (not just the tractor model) – some 46-inch decks use different blade patterns.

Key Things to Know

• Installation: Moderate difficulty. You’ll need a socket wrench and a blade removal tool or block of wood to keep the blade from spinning. Always disconnect the spark plug first.
• Quality: Aftermarket, but rated 4.9/5 from 23 reviews. Users report good balance and durability for residential use.
• Common gotchas: High-lift blades increase engine load slightly – if your mower already struggles on hills or thick grass, you may notice reduced ground speed. Also, they can create more noise and dust.
• Sharpness: Blades come with a cutting edge but may need a quick hone for optimal performance. Check the balance after sharpening.

Should You Buy It

If you own a compatible Husqvarna or Craftsman 46-inch deck tractor or zero-turn and want better bagging or discharge performance without paying OEM prices, this is a solid buy. The high lift is ideal for regular mowing with bagging, but less suited for mulching. For $25, it’s a low-risk upgrade that delivers noticeable improvement in airflow and cut quality.
