GICOOL 405380 Lawn Mower Blade, for 46" Husqvarna YTH22V46 Z246 YT46LS YTH20K46 YTH21K46 YTH22K46 RZ4623 Craftsman CMXGZAM110147 594892801 PP21011 Ariens 21546611, 5-Star Mounting Pattern, 2 Pack

What It Is

This is a 2-pack of aftermarket 46-inch lawn mower blades designed for select Husqvarna, Craftsman, and Ariens zero-turn and riding mowers with a 5-star mounting pattern. They’re for medium-to-large residential lawns, not commercial use.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Only fits 46-inch cutting decks. Measure your deck or check your model number.
• Mounting pattern: Must be a 5-star, 5-point pattern (common on Husqvarna and Craftsman). Measure center hole diameter (usually 7/8” or 1”) and ensure it matches.
• Model compatibility: Confirmed for Husqvarna YTH22V46, Z246, YT46LS, YTH20K46, YTH21K46, YTH22K46, RZ4623; Craftsman CMXGZAM110147, 594892801, PP21011; Ariens 21546611. Cross-reference with your OEM part number (e.g., 405380, 532405380). Not for older or non-5-star decks.

Measure blade length (approx. 20.5” end to end) and center hole width to avoid return headaches.

Key Things to Know

• Quality: High-carbon steel, heat-treated, with hardened edges. Good balance of durability and sharpness for residential use. Not as thick as OEM premium blades, but solid for the price.
• Installation: Easy if you have a socket wrench and blade removal tool. Lift deck, block blades, remove old bolts, install new blades with sharp edge facing up (toward deck). Torque bolts to 40-50 ft-lbs.
• Common gotchas: The 5-star pattern can be tight on some spindles—tap lightly with a mallet if needed. Check for bent spindles before installing. Replace in pairs for even cutting. Not for mulching or bagging use; these are standard lift blades.
• Maintenance: Resharpen after 25 hours of use or if grass tears instead of cuts. Balance after sharpening to avoid vibration.

Should You Buy It

Buy this 2-pack if you have a compatible 46” Husqvarna, Craftsman, or Ariens mower with a 5-star mount and need a budget-friendly, reliable replacement for standard cutting. It’s not for commercial duty or mulching, but for residential lawns, it’s a strong value at $25.99. Avoid if your deck uses a different mounting pattern or you need OEM-specific thickness.
