Husqvarna 580943401 Grass Bag

What It Is

The Husqvarna 580943401 Grass Bag is a genuine OEM replacement bag designed to catch clippings during side-discharge or mulching operation on select Husqvarna walk-behind mowers. It’s a direct-fit part, not a universal accessory.

Fitment & Compatibility

Before buying, verify your mower model against Husqvarna’s compatibility list—this bag fits specific 21-inch and 22-inch walk-behind mowers (e.g., LC121P, LC221A, LC321A, and some LC141 models). Do not assume it fits all Husqvarna mowers. Check your mower’s deck size and bag mount type: this bag uses a rigid plastic adapter that clips onto the mower’s rear discharge chute. Measure the existing bag’s width and hook spacing (roughly 10.5” x 8” opening) to confirm. It is not compatible with Craftsman, Poulan, or other brands unless explicitly listed. OEM vs aftermarket: this is Husqvarna’s own part, so fit is guaranteed for listed models.

Key Things to Know

• Quality: Heavy-duty woven polypropylene fabric with a reinforced bottom and zipper closure. Holds up to moderate use but may fray over time if exposed to sharp debris.
• Installation: Tool-free—slides onto the mower’s discharge chute and clips into place. Takes under 30 seconds. No modifications needed.
• Gotchas: The bag’s frame can warp if left in direct sun or stored wet; dry it before storage. Also, the zipper is the weakest point—avoid overfilling (max capacity ~1.5 bushels). If your mower has a different chute design (e.g., some LC141 variants), this bag may not latch securely.
• No mulching plug included: You’ll need to buy one separately if you want to switch between bagging and mulching.

Should You Buy It

If you own a compatible Husqvarna walk-behind and need a direct, no-hassle replacement, this bag is a solid choice at $39.99. It’s not for universal use or heavy commercial duty—skip it if you have a different brand or want a larger-capacity bag. For occasional homeowner use, it’s a good value.
