Hipa 46-Inch High-Lift Mower Blades for 405380/532405380 2-Pack — Alloy Steel, 5-Point Star Mount

High-lift, 5-point star replacement blades designed to fit 46-inch deck riding mowers (part numbers 405380 / 532405380) for stronger lift and improved grass collection.

These Hipa 46-inch mower blades are built to replace OEM part numbers used on many Husqvarna, Poulan and Craftsman 46" deck tractors and zero-turn mowers. Manufactured from alloy steel with a protective coating, this two-blade pack uses a 5-point star mounting hole pattern and a notched air-lift profile to generate a powerful upward airflow that helps bagging, side discharge and mulching systems perform more efficiently. Before ordering, verify your mower's blade mounting pattern and part number to ensure compatibility.

How do these blades improve cutting and collection?

The high-lift design creates a concentrated upward airflow that lifts grass clippings vertically into the mower’s chute or bagger. That stronger suction leads to cleaner cuts, fuller bags, and better handling of heavier or damp grass without clogging.

• High-lift profile increases airflow for superior collection.
• 5-point star mount ensures secure fit with compatible decks.
• Notched air-lift edge helps prevent clumping and improves discharge.
• Pair of blades balances deck for consistent cut quality.

Which mower models and part numbers are compatible?

These blades are designed to replace part numbers 405380 and 532405380 and match the 5-point star mounting hole configuration found on many 46" Husqvarna, Poulan and Craftsman models. Compatibility can vary by model year, so check your mower’s existing blade marking or owner’s manual before purchasing.

• Compatible with YTH22V46, Z246, YTH21K46 and many 46" ride mowers.
• Also fits models listed under 532403107, 594892801, 21546611 in some years.
• Not suitable for 46" decks with different mounting patterns.
• Verify blade MPN and mounting hole layout before ordering.

What materials and safety features do these blades include?

Constructed from alloy steel (high-carbon mix with chromium and molybdenum additives), these blades prioritize strength, wear resistance and corrosion resistance. The trimmed edge is painted to delay rust formation and to reduce the risk of accidental cuts during installation; the paint will wear with use.

• Alloy steel construction for improved durability and wear life.
• Painted edges reduce rust and protect during handling.
• Inspect blades for cracks, nicks or looseness before each use.
• Always install/remove blades using thick gloves and proper tools.

How should I install and maintain these replacement blades?

Installation requires matching the 5-point star mounting hole and torquing blade bolts to your mower manufacturer’s specification. Routine maintenance—balancing, sharpening if needed, and checking tightness—keeps cut quality consistent and prolongs blade life.

• Match mounting pattern, rotate blade so lift faces deck direction specified by mower.
• Tighten bolts to the torque listed in your mower manual; recheck after first hour of use.
• Keep blades sharp; sharpen both blades equally to maintain deck balance.
• Replace blades if bent, cracked or excessively worn.

Who is this for: These Hipa 46" 5-point high-lift blades are made for homeowners and property managers who need a robust replacement for 46" riding mower decks that use the 5-point star mount—especially those wanting improved bagging and cleaner discharge on thicker or slightly damp grass. They’re not universal replacements; confirm part number and mounting pattern before purchase to ensure proper fit and safe operation.
