631-04354C Side Discharge Chute Assembly Compatible with Cub Cadet MTD Troy-Bilt Lawn Mower, Deflector Replacement for RZT LX XT1 XT2 42 46 Inch Deck, Replaces 631-04354A 631-04354B 731-07020

What It Is

The 631-04354C is a side discharge chute assembly (deflector) that replaces worn or broken OEM parts on select Cub Cadet, MTD, and Troy-Bilt lawn mowers. It directs grass clippings safely away from the cutting deck while preventing debris from hitting the operator or bystanders.

Fitment & Compatibility

Check your mower’s deck size (42- or 46-inch) and model series: this chute fits RZT, LX, XT1, and XT2 models, plus many other MTD-built units with a similar mounting pattern. It replaces OEM part numbers 631-04354A, 631-04354B, and 731-07020. Before buying, measure the distance between the two mounting holes on your deck (typically 5.5–6 inches apart) and confirm the chute’s overall width matches your deck’s chute opening. If your deck uses a different hinge or spring clip, this assembly may not lock in place securely.

Key Things to Know

• Quality vs. OEM: This aftermarket chute is lighter plastic than the original on some models—it works, but may warp in direct sun or crack sooner than OEM under heavy use.
• Installation difficulty: Easy, no tools required for most decks—align the tabs, push down until it snaps into the pivot brackets. If your old chute used a spring or pin, you may need to reuse that hardware.
• Common gotcha: The hinge tabs can be brittle in cold weather; warm the chute slightly (room temp) before snapping on to avoid breakage.
• Fitment nuance: Some users report it fits tightly or loosely on older decks—check that your deck’s chute opening isn’t bent or rusted, which can cause poor alignment.

Should You Buy It

If you need a quick, cheap fix for a broken side chute on a 42- or 46-inch Cub Cadet, MTD, or Troy-Bilt mower and don’t mind slightly thinner plastic, this is a decent budget replacement. For heavy commercial use or if you want a part that closely matches OEM durability, consider the genuine Cub Cadet version instead.
