Husqvarna OEM 42" Fabricated LS Tractor Deck Mulching Kit 587412301

What It Is

This Husqvarna OEM 42" Fabricated LS Tractor Deck Mulching Kit (part #587412301) converts a standard side-discharge or bagging 42-inch fabricated (LS) lawn tractor deck into a mulching system. It’s designed for Husqvarna tractors with the 42-inch fabricated deck, typically found on their LS-series lawn tractors.

Fitment & Compatibility

Before buying, confirm you have a 42-inch fabricated deck (not stamped steel). This kit fits Husqvarna models like the TS142, TS242, TS342, and similar LS-series tractors with a 42" fabricated deck. Check your owner’s manual or look for the deck part number (often stamped on the deck shell) to verify it’s the fabricated version. The kit includes a baffle, plug, and hardware—it will not fit stamped steel decks or non-Husqvarna brands without modification. Measure your deck width (42" from blade tip to blade tip) and ensure the deck is a fabricated (welded) design, not a stamped one.

Key Things to Know

• Quality: OEM Husqvarna parts ensure a precise fit and durable steel construction, but some users report the baffle can warp over time with heavy use.
• Installation difficulty: Moderate—requires removing the deck, installing the baffle under the deck, and swapping the side-discharge chute for the included plug. Expect 30-60 minutes.
• Common gotchas: The kit does not include mulching blades (you’ll need separate high-lift mulching blades for best performance). Also, the plug may not seal perfectly on older decks with rust or debris buildup—clean the chute area thoroughly.
• Performance: Works well for light-to-moderate mulching (dry grass, leaves). For wet or tall grass, you may still see clumps; a second pass helps.

Should You Buy It

Buy this if you own a Husqvarna 42" fabricated deck tractor and want a clean, OEM mulching solution without aftermarket fitment issues. It’s a solid choice for occasional mulching, but skip it if you need heavy-duty mulching or already have mulching blades—you’ll get better results with a dedicated aftermarket kit or a different deck design.
