LC221A LC221AH Pulley Belt Rebuild kit Replace 587973001 580364609 587969201 with 586859604 Blade for Husqvarna 22" AWD Lawn Mowers

What It Is

This rebuild kit includes a replacement blade (586859604) and two belts (587973001, 580364609) for the blade drive and AWD system on Husqvarna 22" AWD lawn mowers (models LC221A and LC221AH). It restores cutting and self-propel function in one package.

Fitment & Compatibility

• Exact fit: Husqvarna LC221A and LC221AH 22" AWD mowers only. Not for other deck sizes or non-AWD models.
• OEM part numbers confirmed: 587973001 (blade belt), 580364609 (AWD belt), 586859604 (blade). Verify your mower’s deck sticker or manual lists these numbers.
• Blade length: 22 inches (measured from tip to tip). Measure your current blade to confirm; aftermarket blades can vary slightly.
• No other brands: Designed exclusively for Husqvarna 22" AWD decks. Will not fit Craftsman, Troy-Bilt, or other brands without modifications.

Key Things to Know

• Two belts included: One for the blade engagement, one for the AWD drive. Both must be replaced together if one is worn to avoid uneven tension.
• Installation difficulty: Moderate. Requires removing the blade, belt covers, and possibly the deck pulley. Have a socket set and belt routing diagram handy.
• Blade is standard steel: Not hardened or mulching-specific. Use for basic cutting; upgrade to a mulching blade separately if needed.
• Low review count (4 reviews): Reliable based on OEM parts, but limited real-world feedback. Buy from a seller with clear return policy.

Should You Buy It

Buy this kit if you own a Husqvarna LC221A or LC221AH and need to replace both the blade and drive belts at once. It’s a convenient, OEM-matched solution for restoring full function, but skip it if you only need a single belt or a mulching blade—you’ll overpay for parts you don’t use.
