lauterbrun Lawn Mower Grass Bag Dupe , suitable for Husqvarna models 580943406 ,580943407, 580943404, 580943401, and 422517, and also compatible with HU700H models (excluding the Grass Catcher Frame)

What It Is

This is an aftermarket replacement grass bag dupe for Husqvarna walk-behind mowers, designed to catch clippings during standard lawn cutting. It suits models using OEM part numbers 580943406, 580943407, 580943404, 580943401, and 422517, and also fits HU700H series mowers (without the frame).

Fitment & Compatibility

• Check your mower’s deck size: This bag is intended for 21-inch and 22-inch Husqvarna walk-behind mowers. Measure your deck width to confirm.
• Model confirmation: Verify your mower’s model number (e.g., HU700H, HU700H AWD, HU700H RWD) against the listed OEM part numbers. This bag replaces the original Husqvarna grass bag, not the catcher frame—ensure your mower has the frame already installed.
• OEM vs. aftermarket: This is a dupe, not genuine Husqvarna. It matches the dimensions and attachment points of the OEM bag, but fitment may vary slightly on older or non-standard mowers.
• Physical check: The bag measures roughly 20 x 12 x 12 inches. Confirm your mower’s bag mounting bracket is not damaged or warped—this can cause a poor seal.

Key Things to Know

• Quality vs. OEM: Users report the bag is durable for its price but uses lighter material than the original. It may wear faster under heavy use or in wet grass.
• Installation is simple: Attaches directly to the existing frame—no tools needed. Just slide the bag onto the hooks and secure the strap.
• Common gotcha: The bag may not seal as tightly as OEM, leading to minor grass spillage on uneven terrain. Check the rubber flap alignment after mounting.
• Frame not included: If your mower is missing the catcher frame, this bag won’t work—buy the frame separately.

Should You Buy It

Buy this if you need a budget-friendly replacement for a worn-out Husqvarna grass bag on a 21-22 inch walk-behind mower and already have the frame. It’s a solid value for light-to-medium use, but if you mow thick, wet grass frequently or want maximum durability, consider the OEM bag instead.
