Husqvarna Lawn Mower Bags Compared: Which Grass Catcher Fits Your Mower?

Best for
Owners wanting official OEM factory parts

The Husqvarna 587100402 21″ Black Grass Catcher is an authentic factory replacement component manufactured for 21-inch cutting decks. This genuine equipment option ensures exact alignment with the rear discharge hatch on modern walk-behind machines. It serves as a functional replacement for superseded part numbers including 587100409, 587100408, 586100402, 587100407, 587100415, 587100416, and 587100417. It fits popular residential models such as the LC221A, LC221RH, LC221FH, LC221Z, LC221AH, L321AHE, and L221AK.

This option suits owners who prefer official brand components that maintain strict manufacturing tolerances. The listing specifies manual operation, a weight of 16 ounces, and compatibility across 9 deck height positions. The manufacturer explicitly recommends wearing work gloves during installation to prevent hand abrasion while seating the mounting points. For optimum bagging efficiency, pair this catcher with sharp husqvarna lawn mower blades that generate proper upward lift through the cutting chamber.

Where this model stands out is its guaranteed fitment for the LC221 and L321 mower families. However, it yields to aftermarket fabric sleeves when owners are maintaining older HU-series decks that utilize separate frame wire setups not matched to this component number.

With package dimensions of 15.91 by 5.75 by 3.9 inches and a weight of 1.7 pounds, it provides ample collection volume for typical suburban residential yards.

Because it does not include steel support wire, this bag gives way to complete assemblies like the 587100402 when an owner has lost or bent their original metal mounting hardware. It also yields to smaller specialized bags when outfitting compact push models like the 5521P.

• Broad compatibility covering Husqvarna HD and HU walk-behind series

When looking up a husqvarna grass bag by model number, owners of classic manual machines will find this bag matches the 5521P, 5521L, 7021P, 6751P, and LC121P lines.

This 581002112 grass bag husqvarna 5521P compatible option suits homeowners seeking an exact fabric sleeve for push mowers with 21-inch cutting decks. The listing specifies durable plastic construction in black, a weight of 0.7 kilograms (approximately 1.54 pounds), a single mounting position, and manual push operation. Because it is a fabric-only replacement, the listing notes that the grass catcher frame is not included, requiring owners to slide the material over their existing factory metal rim.

For homeowners tired of manual bagging on small yards, looking into automated alternatives like a husqvarna robot mower can eliminate bagging chores entirely. Otherwise, this model remains the definitive choice for the 5521 and 7021 push mower series, giving way only to larger-volume HU-series bags on all-wheel-drive mowers.

When outfitting riding equipment, owners frequently compare complete assemblies like a husqvarna bagger kit or a compatible craftsman riding mower bagger setup to ensure complete deck-to-chute compatibility.
