Braveboy 964-05104 964-04090A 964-04096A Grass Bag Assembly Compatible with MTD/Troy Bilt/Cub Cadet/Craftsman RZT 42 44 46 48 50 54 60 S, w/Hard Bottom (1 Pack)

What It Is

This is an aftermarket grass bag assembly designed for select zero-turn and lawn tractor models from MTD, Troy-Bilt, Cub Cadet, and Craftsman. It replaces OEM part numbers 964-05104, 964-04090A, and 964-04096A, and includes a hard plastic bottom to prevent sagging and improve bagging performance.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: This bag fits 42, 44, 46, 48, 50, 54, and 60-inch cutting decks on compatible models.
• Model series: Works with RZT series zero-turns (RZT 42, 44, 46, 48, 50, 54, 60 S) and similar MTD-built tractors. Check your owner’s manual for OEM part numbers 964-05104, 964-04090A, or 964-04096A.
• Physical fit: Measure the bag mounting bracket spacing and bag opening dimensions on your machine. This bag uses a standard hook-and-pin attachment common on these brands, but older or non-standard brackets may require modification.

Key Things to Know

• Hard bottom is a plus: The rigid base keeps the bag shape under heavy loads, reducing clogging and making emptying easier than soft-bottom alternatives.
• Installation is straightforward: No tools needed—hooks slide into the mower’s bag bracket and the bottom lip seats into the discharge chute. Takes 2–5 minutes.
• Durability is decent for the price: The fabric is heavy-duty polyester, but the zipper and seams are not indestructible. Avoid overfilling or dragging the bag on rough surfaces.
• Check your bag bracket: Some MTD/Troy-Bilt models use a two-bag system (one per side). This is a single bag—ensure your mower’s bracket accommodates one bag or buy a pair if needed.

Should You Buy It

If you need a functional, budget-friendly replacement for a worn or missing bag on a compatible MTD/Troy-Bilt/Cub Cadet/Craftsman zero-turn or lawn tractor, this is a solid choice. It’s not premium-grade, but the hard bottom and reliable fit make it a good value for occasional to moderate use. Avoid it if you need OEM-level durability for heavy commercial use.
