What It Is

This is a complete 46-inch deck rebuild kit for Husqvarna YTH22v46, YTH21k46, and YTH20k46 riding mowers. It includes two spindle assemblies, two blades, a belt, and a pulley—everything needed to restore a worn or damaged cutting deck to like-new performance.

Fitment & Compatibility

Before buying, confirm your mower’s model number (e.g., YTH22v46) and that the deck measures exactly 46 inches. This kit is designed for Husqvarna tractors with a stamped steel 46-inch deck, not fabricated or fabricated-style decks. The spindle assemblies are OEM-style replacements (part 587819701), the pulley is 532197473, blades are 532405380, and the belt is 1/2x106 inches. If your mower uses a different belt length or blade part number, this kit won’t fit. Check your owner’s manual or existing parts for exact numbers.

Key Things to Know

• Quality varies – Some users report spindles are serviceable but not as robust as OEM Husqvarna parts. Inspect for burrs or rough bearings before installation.
• Installation is moderate – Requires basic tools (socket set, jack, safety stands). Expect 1–2 hours if you’ve done deck work before, longer if not. Watch for stripped bolts on old spindles.
• Blades are standard – The included 532405380 blades are 18.5 inches long, 1 inch wide, with a 1-inch center hole. They fit most 46-inch Husqvarna decks, but verify your deck’s blade orientation (some use a different offset).
• Belt is a common size – 1/2x106 inches fits many 46-inch Husqvarna decks, but always double-check belt routing diagrams to avoid misalignment.

Should You Buy It

This kit is a good value if you need to replace multiple deck components at once and your mower matches the listed models exactly. It saves money over buying parts individually, but quality isn’t top-tier—fine for typical residential use, not for heavy commercial cutting. If you only need one spindle or blade, buy separately.
