2PK USA Toothed Mulching Mower Blade for 46" Husqvarna YTH22V46

What It Is

This is a set of two toothed mulching mower blades designed for 46-inch Husqvarna YTH22V46 lawn tractors. They chop grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

• Deck size: Only fits 46-inch cutting decks. Measure your deck width to confirm.
• Model compatibility: Designed for Husqvarna YTH22V46, but may fit other Husqvarna models with a 46-inch deck (e.g., YTH24V46, YTH18542). Check your owner’s manual or deck underside for OEM part numbers (often 532 40 78-01 or similar).
• Aftermarket vs OEM: These are non-OEM blades. Verify blade length (typically 21.5 inches), center hole diameter (usually 1 inch), and drive pin/star pattern match your spindle.
• What to check before buying: Count the number of blades on your current setup (should be 2). Inspect your spindle for wear or damage. Ensure the blade’s lift and cut angle match your deck design.

Key Things to Know

• Quality: These are toothed mulching blades—thicker and more aggressive than standard lift blades. They may produce a finer cut but can dull faster on sandy or rocky soil.
• Installation: Moderate difficulty. You’ll need a socket wrench, torque wrench (set to 70-90 ft-lbs), and safety blocks. Always disconnect the spark plug and battery before working.
• Common gotcha: Toothed blades can create more vibration if not balanced after installation. Use a blade balancer to avoid wobble and spindle damage.
• Performance: Expect better mulching in dry grass; wet or tall grass may clog the deck. Clean the underside frequently.

Should You Buy It

If you own a 46-inch Husqvarna tractor and want to mulch leaves or grass without bagging, this two-pack is a cost-effective choice. However, with only one rating and limited reviews, verify exact fitment with your model number. It’s best for users comfortable with DIY blade swaps and who prioritize fine mulching over longevity.
