deawater 731-09173A 731-09329A Lower Bagger Chute, Bagger Boot Compatible with MTD Cub Cadet Craftsman Troy-Bilt 42" 46" Leaf

What It Is

This is a replacement lower bagger chute (also called a bagger boot) that connects your mower deck’s discharge opening to the bagger system. It’s designed for 42” and 46” MTD-built lawn tractors from Cub Cadet, Craftsman, and Troy-Bilt, directing grass clippings and leaves into the collection bags.

Fitment & Compatibility

• Deck sizes: 42” and 46” only. Measure your deck width before ordering.
• Brand fit: Fits Cub Cadet, Craftsman, Troy-Bilt, and other MTD-built tractors with compatible bagger systems (e.g., 190-681, 190-692, 490-241-0003, 490-241-0004).
• OEM part numbers: Replaces 731-09173A and 731-09329A. Aftermarket part, not OEM Cub Cadet.
• Check your chute mounting: This is the lower chute (boot) that attaches to the deck. It does not include the upper chute or bagger frame. Ensure your existing upper chute and bagger frame are intact.
• Measurement: Overall chute width is roughly 6.5” at the deck opening; verify your deck’s discharge opening matches.

Key Things to Know

• Quality: Made from heavy-duty polyethylene plastic—durable but not unbreakable. Avoid hitting curbs or rocks.
• Installation: Moderate difficulty. You’ll need to remove the old chute and possibly the deck belt guard. No special tools required, but a socket set helps.
• Common gotcha: Some users report the chute doesn’t seal perfectly on older decks with bent mounting tabs. Check your deck’s discharge plate for damage before buying.
• Fitment note: Works with both single-bag and twin-bag systems, but verify your bagger model number if you have a non-MTD brand.

Should You Buy It

Buy this if your original lower chute is cracked, broken, or missing and you have a 42” or 46” MTD-built tractor (Cub Cadet, Craftsman, Troy-Bilt) with a compatible bagger. It’s a solid aftermarket replacement at a fair price, but skip it if you need the upper chute or if your deck’s discharge area is bent—you’ll need to fix that first.
