CUB CADET 964-04066 Grassbag Assembly ES CC550SP CC550ES CC500BAT CC500 CC189

What It Is

The CUB CADET 964-04066 Grassbag Assembly is a OEM replacement grass collection bag for select Cub Cadet push mowers with a 22-inch deck. It mounts to the rear of the mower to catch clippings during bagging operation.

Fitment & Compatibility

Check your mower model and deck size before buying. This bag fits the following Cub Cadet models: CC550SP, CC550ES, CC500BAT, CC500, and CC189. It is designed for 22-inch deck mowers only. The 964-04066 is the OEM part number from Cub Cadet; aftermarket bags may differ in fit and durability. Measure your existing bag’s hook spacing and bag frame width – this bag uses a hard plastic frame with two metal hooks that attach to the mower’s rear bracket. If your mower has a different deck size (e.g., 21-inch or 30-inch), this bag will not work.

Key Things to Know

• Quality: OEM construction with heavy-duty fabric and a rigid plastic frame. Users report the bag holds up well for a season or two, but fabric can tear if overfilled or dragged.
• Installation: Simple snap-on attachment – hooks slide into the mower’s rear bracket, and the bag rests on the ground. No tools required.
• Common gotchas: The bag may not sit flush on uneven terrain; check that the hooks are fully seated to avoid the bag falling off mid-mow. Also, the plastic frame can crack if you step on it or store it with heavy weight on top.
• Bag capacity: Holds roughly 1.5 to 2 bushels of grass. For larger lawns, you may need to empty frequently.

Should You Buy It

If you own one of the listed Cub Cadet models and need a direct replacement for a worn or damaged bag, this OEM part is a reliable choice for fit and durability. It’s not the cheapest option, but it avoids the guesswork of aftermarket bags. Skip it if your mower is a different model or deck size, or if you prefer a hard-side (non-fabric) bag.
