580943406 Lawn Mower Grass Bag Dupe Suitable for Husqvarna 580943401,580943407, 580943404, 422517, HU700H Models (excluding The Grass Catcher Frame) Prepare the Perfect Yard for the World Cup

What It Is

This is an aftermarket grass collection bag designed for Husqvarna walk-behind mowers, specifically replacing OEM part numbers 580943401, 580943407, 580943404, and 422517. It fits Husqvarna HU700H series mowers and is intended for bagging grass clippings during routine mowing—not for heavy-duty commercial use or World Cup-level turf prep (that’s marketing fluff).

Fitment & Compatibility

Before buying, confirm your mower’s deck size (usually 21″ or 22″) and model number. This bag is a “dupe” (aftermarket) that fits Husqvarna HU700H, HU725H, and HU775H models, plus some Poulan Pro and Craftsman units using the same OEM bag numbers. It does not include the grass catcher frame—you must reuse your existing frame or buy one separately. Measure the bag attachment hooks and the frame’s mounting slots; if your mower uses a different bag attachment system (e.g., quick-release or pin-style), this won’t work. Check the bag’s listed dimensions (typically 18" x 12" x 10") against your mower’s bag opening.

Key Things to Know

• Quality vs. OEM: Aftermarket fabric may be thinner and less UV-resistant. Expect 1-2 seasons of home use, not heavy abuse.
• Installation: Simple—slide bag onto frame, secure with straps or clips. No tools needed.
• Common gotcha: If your mower has a rear-discharge plug or mulching plate, you must remove it before bagging. Also, ensure the bag’s venting isn’t blocked; poor airflow reduces collection.
• Capacity: Typically holds about 1.5–2 bushels. Overfilling causes clogging at the chute.

Should You Buy It

Buy this if you need a budget-friendly replacement for a worn-out Husqvarna bag and already have the frame. It’s fine for a typical suburban lawn, but skip it if you want OEM durability or need a complete bagging system (frame included). For the price, it’s a practical stopgap—just don’t expect it to survive a World Cup match.
