DeWalt OEM N511149 Lawn Mower Grass Bag DCMW290H1 DCMW290H1 DCMW220X2 DCMW220P2

What It Is

This is the OEM replacement grass bag for DeWalt cordless mowers, designed to catch clippings during mulching or bagging. It fits select 20V MAX mower models, including the DCMW290H1, DCMW220X2, and DCMW220P2.

Fitment & Compatibility

Before buying, confirm your mower model matches one of the listed units exactly. This bag is not universal—it will not fit other DeWalt mowers or different brand decks. Check the bag mounting bracket and attachment points on your mower; the N511149 uses a specific hook-and-frame interface. Measure the bag’s approximate dimensions (roughly 18" x 12" x 10") to ensure it clears your deck and storage space. This is a genuine DeWalt OEM part, so it’s a direct swap with no modification needed.

Key Things to Know

• Quality concerns: The 3.2-star rating suggests some users report stitching or zipper failures after moderate use. Inspect seams immediately upon arrival.
• Installation: No tools required—just slide the bag onto the mower’s chute and secure the hooks. Takes under a minute.
• Common gotcha: The bag may not seal tightly against the deck on older mowers, leading to clippings escaping. Check the rubber flap on the chute for wear.
• Capacity: Holds about 1.5 bushels—sufficient for small to medium lawns, but you’ll empty it frequently on tall or damp grass.

Should You Buy It

This is the only direct-fit replacement for your specific DeWalt mower, so if the original bag is torn or missing, it’s your best bet. Skip it if you want a larger capacity or higher durability—consider a universal aftermarket bag with adjustable brackets for a more robust option.
