Braveboy 581002112 Lawn Mower Grass Bag, Compatible with Husqvarna, Fits Model 5521P 5521L 6751P 7021P LC121P5810021 12581002112 & More - (Without Grass Catcher Frame)

What It Is

This is an aftermarket replacement grass bag for Husqvarna walk-behind mowers. It collects clippings during mowing and is designed for models with a 21-inch deck.

Fitment & Compatibility

• Fits Husqvarna models: 5521P, 5521L, 6751P, 7021P, LC121P, and others using OEM part 581002112 or 12581002112.
• Deck size: 21-inch cutting deck only. Measure your deck width before buying.
• No frame included: This is the bag only. You must already have the grass catcher frame (metal support) on your mower. If you need the frame, this won’t work.
• Check bag attachment type: The bag hooks onto the mower’s rear discharge chute with two plastic clips. If your mower uses a different method (e.g., side-discharge or pin-style), this won’t fit.
• Measure bag dimensions: Approx. 18 x 12 x 10 inches. Confirm your frame can accommodate these dimensions.

Key Things to Know

• Material: Made from woven polypropylene—durable but not as thick as OEM. May wear faster with heavy use.
• Installation: Easy—hook clips onto the mower’s rear chute tabs. No tools needed.
• Common gotcha: The bag’s top opening is slightly smaller than OEM. You may need to stretch it over the frame’s metal lip. If the frame is bent or rusty, fitment will be tight.
• Capacity: Holds about 1.5 bushels (similar to OEM). Good for small to medium lawns (under ¼ acre). For larger lawns, you’ll need to empty more often.

Should You Buy It

If you already have a Husqvarna 21-inch mower with the grass catcher frame and just need a replacement bag, this is a budget-friendly choice. It’s not as tough as OEM but works well for occasional use. Skip it if you need the frame, have a different brand mower, or mow heavy, wet grass regularly (the bag may clog or tear faster).
