Riding Tractor Mulch Cover Kit 46" Deck Husqvarna YTH22V46 Z246 532406581

What It Is

This is a universal mulch cover kit for 46-inch cutting decks on Husqvarna riding tractors. It replaces the side-discharge chute with a sealed plate and baffle that recirculates grass clippings for finer mulching.

Fitment & Compatibility

• Deck size: Fits 46-inch (117 cm) decks only. Measure your deck width before ordering.
• Model match: Direct fit for Husqvarna YTH22V46, Z246, and most 46-inch deck Husqvarna tractors from 2010 onward. Also compatible with some AYP, Craftsman, and Poulan Pro models using the same deck shell.
• OEM vs aftermarket: This is OEM Husqvarna part number 532406581. Aftermarket alternatives exist but may require hardware adjustments.
• Check mounting holes: Verify your deck has the two pre-drilled holes at the discharge opening for the included bolts. Some older or non-Husqvarna decks may need drilling.

Key Things to Know

• Installation difficulty: Easy – 15 minutes with a socket wrench. No deck removal needed.
• Quality: Sturdy stamped steel with powder coating. Holds up well, but the gasket/seal can degrade after 2-3 seasons in wet conditions.
• Common gotcha: The kit does not include a replacement blade. For best mulching results, install a dedicated mulching blade (sold separately) with a higher lift angle.
• Performance note: Works best on dry grass under 4 inches. Wet or tall grass will clump and leave clippings on the lawn.

Should You Buy It

Buy it if you have a compatible 46-inch Husqvarna deck and want a cleaner lawn without bagging – especially for dry, frequent mowing. Avoid if you need heavy-duty mulching in wet conditions or want a full mulching system with a blade kit included. At $29, it’s a cheap upgrade that saves you from raking, but don’t expect perfect results without the right blade and mowing habits.
