Husqvarna 581116302 Lawn Tractor 38-in Deck 3-in-1 Blade Genuine Original Equipment Manufacturer (OEM) Part

What It Is

This is a genuine OEM 3-in-1 blade for Husqvarna lawn tractors with a 38-inch cutting deck. It enables mulching, bagging, and side-discharge operations, designed for residential use on standard turf.

Fitment & Compatibility

Before buying, confirm your tractor has a 38-inch deck (measure cutting width, not chassis). This blade fits Husqvarna LGT series models (e.g., LGT2554, LGT2654) and select GTH/GT models with 38-in decks. Check your owner’s manual or existing blade part number—Husqvarna 581116302 supersedes older 532581116. Do not assume it fits non-Husqvarna brands; aftermarket blades with the same length may differ in center hole shape or thickness. Measure your current blade: length should be ~19.5 inches (center hole to tip), width ~2.5 inches, with a 20mm center hex hole. Verify spindle bolt size (usually 5/16-inch or 3/8-inch) and that the blade aligns with your deck’s lift wings.

Key Things to Buy

• OEM quality vs. aftermarket: Genuine Husqvarna steel is heat-treated for durability and factory-balanced. Aftermarket blades may be cheaper but often lack consistent hardness or balance.
• Installation difficulty: Moderate. Requires a socket wrench, torque wrench (40-50 ft-lbs), and a block of wood to jam the blade. Always disconnect the spark plug and wear gloves—blades are sharp.
• Common gotchas: The blade can be installed upside down (lift wings must point up toward the deck). Check blade alignment after tightening; wobble indicates a bent spindle or incorrect seating.
• Performance note: The 3-in-1 design is a compromise—mulching quality is decent but not as fine as a dedicated mulching blade. Bagging works well if your deck has a proper chute.

Should You Buy It

If you own a Husqvarna 38-inch deck tractor and want a straightforward drop-in replacement with guaranteed fit and OEM durability, this blade is a solid choice. It’s ideal for homeowners who need one blade to handle all three functions without swapping. However, if you prioritize superior mulching or have a non-Husqvarna deck, consider a dedicated aftermarket mulching blade or verify fitment carefully first.
