2PK USA Mulching Mower Blade for 46" Husqvarna YTH22V46

What It Is

This is a 2-pack of mulching blades designed for 46-inch Husqvarna YTH22V46 lawn tractors. They cut grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be exactly 46 inches. Measure deck width if unsure.
• Model fit: Designed for Husqvarna YTH22V46, YTH22V48, and similar 46" cutting deck models. Check your owner’s manual or existing blade part number.
• OEM vs aftermarket: These are aftermarket replacements. OEM part numbers include 532 40-47-05 or 532 41-67-80. If your machine uses a different blade pattern (e.g., Gator blades), these won’t fit.
• Blade measurements: Each blade is roughly 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.5-inch offset. Verify your blade’s length and hole size.

Key Things to Know

• Mulching vs. standard: These are mulching blades, not lift blades. They work best for frequent mowing (every 3-5 days) with dry grass. Avoid using them for bagging or side discharge.
• Installation difficulty: Easy if you have a socket wrench and jack stands. Always disconnect the spark plug and lift the mower safely. Torque blade bolts to 40-50 ft-lbs.
• Sharpness out of box: They come sharp but may need a quick hone after first use if you hit debris.
• Balance check: After sharpening, always balance the blades to prevent vibration and bearing wear.

Should You Buy It

Buy these if you have a 46" Husqvarna tractor, mow frequently, and want to leave clippings on the lawn for natural fertilizer. Skip them if you prefer bagging, side discharge, or have a different deck size. At $27.95 for two blades, they’re a solid value for DIY maintenance.
