What It Is

This is an aftermarket grass collection bag designed for Husqvarna walk-behind mowers. It replaces the OEM bag to catch clippings during mowing, saving you from raking.

Fitment & Compatibility

Before buying, confirm your mower model—it fits Husqvarna HU700H, HU725E, and HU775H (and likely other HU-series models with similar rear bagger mounts). Check your deck size: these models typically have 21-22” decks, but measure your bag attachment bracket width and height. It replaces OEM part numbers 580943401, 580943404, 580943407, and 422517. If your mower uses a different bag attachment system (e.g., side-discharge or mulching only), this won’t work.

Key Things to Know

• Quality vs OEM: As a dupe, it may use thinner fabric or less rigid frame—expect slightly shorter lifespan than Husqvarna’s original bag.
• Installation: Usually snaps or hooks onto the rear bracket; no tools needed. Check that the bag’s mounting hooks align with your mower’s pins.
• Common gotcha: The bag may not seat as tightly as OEM, causing minor grass spillage if the latch is loose. Ensure your mower’s bagger bracket is clean and undamaged.
• Capacity: Likely matches OEM at ~1.5-2 bushels—fine for small to medium lawns, but may fill faster on thick grass.

Should You Buy It

If you own a compatible Husqvarna HU-series mower and need a budget-friendly replacement for a worn or missing bag, this is a solid choice for casual use. But if you mow large, heavy lawns daily or want maximum durability, stick with the OEM bag.
