Husqvarna 587100402 21" Black Grass Catcher Bag LC221Z LC221AH Walk-Behind Lawn Mowers

What It Is

This is an OEM Husqvarna 21-inch black grass catcher bag (part number 587100402) designed to collect clippings during mowing. It’s specifically for Husqvarna LC221Z and LC221AH walk-behind mowers.

Fitment & Compatibility

• Deck size: Fits only 21-inch cutting decks on the LC221Z and LC221AH models.
• Model check: Confirm your mower is a Husqvarna LC221Z or LC221AH. It will not fit other Husqvarna 21-inch models (e.g., LC221A, LC221FH) without verifying bag mounting bracket design.
• OEM vs aftermarket: This is genuine Husqvarna, so it matches the original bag’s dimensions, mounting hooks, and attachment points. Aftermarket bags may use different hook spacing or fabric weight.
• Measurements: Bag is approximately 21 inches wide and 12 inches tall. Measure your mower’s bag holder width and hook positions (usually two plastic hooks on the handlebar) to confirm compatibility.

Key Things to Know

• Quality: Sturdy black woven polypropylene fabric with reinforced seams. Holds up well to regular use but can tear if overfilled with wet grass or debris.
• Installation: Simple – snaps onto the mower’s bag holder hooks via two plastic clips. No tools needed. Takes under a minute.
• Common gotchas: The bag may not fully seal if the mower’s discharge chute or bag holder is bent or damaged. Check those parts for cracks or warping before buying.
• Capacity: Holds about 1.5 bushels – fine for average yards, but you’ll empty it often on tall or damp grass.

Should You Buy It

If you own a Husqvarna LC221Z or LC221AH and need a direct-fit replacement for a worn or torn original bag, this is the right choice. It’s a simple, reliable OEM part that installs quickly and works as intended. Skip it if your mower is a different model or if you want a larger-capacity aftermarket bag.
