OEM Replacement - for Husqvarna 580364609 580364605, Compatible with Husqvarna LC221A LC221AH L321AHE LFC221A L221A - Durable, Aramid Cord Belt

What It Is

This is an OEM replacement belt for Husqvarna walk-behind mowers, specifically models in the LC200 and L300 series. It drives the blade and self-propel system, using a durable aramid cord construction for longer wear under heavy use.

Fitment & Compatibility

Before buying, confirm your mower model is on the Husqvarna LC221A, LC221AH, L321AHE, LFC221A, or L221A list. This belt replaces OEM part numbers 580364609 and 580364605. Measure your old belt’s length (typically 37.5 inches) and width (0.5 inches) to match. It fits 21-inch deck models with a single-blade, self-propelled system. Not compatible with aftermarket decks or older Husqvarna models outside the LC200/L300 series.

Key Things to Know

• Aramid cord resists stretching and heat better than standard rubber belts, so it lasts longer in dusty or heavy grass.
• Installation is straightforward: remove the belt cover, release tension by compressing the idler pulley, and route the belt per the diagram under the deck. No special tools needed.
• Common gotcha: The belt must be routed correctly around the blade pulley, transmission pulley, and idler. Misrouting causes slipping or no drive. Take a photo before removal.
• Check pulley condition – worn or bent pulleys will quickly destroy a new belt. Replace any that are rough or wobbling.

Should You Buy It

If you own a compatible Husqvarna LC200 or L300 series mower and want a direct-fit, long-lasting replacement, this belt is a solid choice. It’s priced competitively with aftermarket options but offers OEM fit and aramid durability. Avoid if your pulleys are worn or if you need a belt for a different brand or deck size.
