Exmark 126-2630 21 Grass Bag ECS180GKA21000 ECX160CHN21000 ECX180CKA21000 ECX180CKA210BC

What It Is

This is an OEM replacement grass collection bag for select Exmark 21-inch walk-behind mowers. It is designed to catch clippings during mulching or bagging operation, with a 2-bushel capacity suitable for residential or light commercial use.

Fitment & Compatibility

Check these before buying:

• Exact models: ECS180GKA21000, ECX160CHN21000, ECX180CKA21000, ECX180CKA210BC. No other Exmark models or brands are confirmed compatible.
• Deck size: Only for 21-inch decks. Will not fit 32-inch, 36-inch, 48-inch, etc.
• OEM vs aftermarket: This is genuine Exmark OEM. Aftermarket bags may fit but often have different attachment hooks or bag shape.
• Measurements: Approx 21" x 12" x 12". Verify your current bag dimensions and attachment bracket spacing.

Key Things to Know

• Quality: Heavy-duty fabric with reinforced seams. Holds up better than budget aftermarket bags, but the zipper is a common failure point after 1–2 seasons of heavy use.
• Installation: Simple – slides onto the mower’s bag bracket and clips into place. No tools required. Takes under 2 minutes.
• Common gotcha: The bag hooks may not align perfectly with older mower brackets (pre-2015). If your bracket is bent or worn, the bag may sag or detach mid-mow.
• Capacity: 2 bushels (approx. 1.5 cubic feet). Fine for small lawns; you’ll need to empty frequently on thick or wet grass.

Should You Buy It

Buy this if you own one of the listed Exmark 21-inch models and need a direct OEM replacement that fits without guesswork. If your bag is torn or the zipper is broken, this is the correct fix. Skip it if you’re looking for a larger capacity, a universal bag, or if your mower is a different brand – in those cases, an aftermarket universal bag or a different OEM part will serve you better.
