CUB CADET 764-04082D 21" Grass Bag SC100 HW SC300 E HW Push Lawn Mowers 964-04155 764-04082A

What It Is

This is an OEM replacement grass bag assembly for select Cub Cadet push mowers with 21-inch decks. It collects clippings during mulching or bagging operation and replaces worn or torn original bags.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch cutting deck and is one of these models: SC100, SC300, E, or HW series push mowers. The bag replaces part numbers 764-04082A, 964-04155, and 764-04082D. Measure the bag opening width (approx. 10 inches) and check that your mower’s rear discharge chute aligns with the bag’s mounting hooks. It will not fit zero-turn, riding, or walk-behind mowers with different deck sizes.

Key Things to Know

• Material quality: OEM build with sturdy fabric and reinforced seams; holds up better than most aftermarket bags.
• Installation: Slides onto the mower’s rear hooks and secures with a strap. Tool-free, takes under 2 minutes.
• Common gotcha: The bag’s plastic frame can crack if overstuffed or left in direct sun. Store indoors.
• Capacity: Holds about 1.5 bushels—fine for average lawns, but frequent emptying needed for thick, wet grass.

Should You Buy It

If your original bag is torn, the frame is broken, or the zipper has failed, this direct replacement saves you the hassle of rigging a universal bag. It’s a solid choice for owners of compatible Cub Cadet push mowers who want reliable, OEM-fit performance without modifying the mower.
