What It Is

This is a belt and pulley repair kit for Husqvarna AWD (All-Wheel Drive) lawn mowers. It includes two pulleys (587973001 and 587969201) and one belt (580364609) to replace worn drive components on models like the L 321AHX and L 321AH.

Fitment & Compatibility

Before buying, confirm your mower model is Husqvarna L 321AHX or L 321AH (check the model plate under the seat or on the frame). This kit replaces OEM part number 580364603. Measure your old belt length and pulley diameter to match—this belt is for AWD systems only, not standard push or self-propelled mowers. Avoid assuming it fits other Husqvarna models; cross-reference your mower’s serial number with the kit’s part numbers.

Key Things to Know

• Quality: OEM-grade construction; pulleys are steel with sealed bearings. Belt is Kevlar-reinforced for long life.
• Installation: Moderate difficulty—requires removing the mower deck and belt covers. A spring puller tool helps with tension.
• Gotcha: The belt routing diagram is printed on the kit’s packaging; take a photo of the original belt path before removal.
• Common issue: If your mower’s AWD slips or makes noise, replace pulleys and belt together—worn pulleys quickly damage a new belt.

Should You Buy It

If you own a Husqvarna L 321AHX or L 321AH with AWD performance issues (slipping, squealing, or uneven drive), this kit is a cost-effective fix. It’s ideal for DIYers with basic mechanical skills who want OEM-level reliability without paying dealer prices.
