What It Is

This is a genuine OEM Husqvarna replacement blade for zero-turn mowers, designed for high-lift cutting on residential and commercial decks. It’s a straight, 20.5-inch blade with a 1-inch center hole and 0.25-inch thickness.

Fitment & Compatibility

Before buying, measure your existing blade length (center hole to tip) and confirm it matches 20.5 inches. The part number 587412301L (and its variants like 587412301a, 587412301w) is the same blade—different suffixes indicate packaging or minor revisions. This blade fits Husqvarna zero-turn models with 48-inch, 48.5-inch, and 54-inch decks (e.g., Z242F, Z254, Z4217, Z4817). It also works on some Poulan Pro, Craftsman, and McCulloch zero-turns that use the same blade pattern. Always check your owner’s manual or measure your old blade’s hole diameter and length—aftermarket blades with similar dimensions may fit but lack OEM quality control.

Key Things to Know

• Quality: OEM Husqvarna steel is heat-treated and balanced for longevity. Aftermarket blades can save money but often dull faster or cause vibration.
• Installation: Easy if you have a socket set and a blade removal tool or a block of wood to wedge the blade. Torque the bolt to 40–50 ft-lbs.
• Common gotchas: The high-lift design throws clippings far but increases engine load—use on dry grass to avoid bogging. Don’t sharpen beyond the factory edge; replace if bent or chipped.
• Variants: The “L” suffix is the standard part. If you see “T” or “r,” they’re the same blade—just different packaging runs.

Should You Buy It

If you own a Husqvarna zero-turn with a 48–54-inch deck and want reliable, OEM-spec cutting performance with minimal vibration, this blade is a direct, no-guesswork upgrade. It’s overkill for push mowers or small decks, and the price is higher than generic options—but for commercial or heavy residential use, the durability justifies it.
