Kerlista 631-04354C is a direct-fit replacement side discharge deflector chute for select Cub Cadet and compatible lawn tractors, restoring safe and efficient grass discharge.

If your mower’s side chute is cracked, warped, or missing, this replacement assembly gets clippings flowing away from the deck again and helps keep cut lines clean.

It replaces OEM numbers including 631-04354A/B/C and related variants, and fits numerous Cub Cadet, MTD, Troy-Bilt, Murray and Craftsman models with 42" and 46" decks.

How durable and reliable is the replacement chute?

Kerlista manufactures this chute from robust, weather-resistant plastic formulated to resist cracking and wear under normal mowing use. The construction is intended to stand up to repeated blade airflow, debris impact and outdoor storage without rapidly degrading.

• High-quality molded material for impact and UV resistance
• Reinforced mounting edges to reduce stress at attachment points
• Finished surface that sheds wet clippings and resists buildup
• OEM-compatible shape to avoid rubbing or interference with deck parts

Is it easy to install and what does the package include?

Yes — the chute is built to be a drop-in replacement for the listed OEM part numbers so most replacements require just basic hand tools. The kit arrives ready to mount, letting you swap out a worn part quickly and get back to mowing.

• Package includes: 1 set side discharge deflector chute
• Direct replacement for OEM #631-04354C and related numbers
• Simple bolting arrangement — no special brackets required
• Inspect existing fasteners and clips; replace if corroded for best fit

Will this affect mowing performance or safety?

Replacing a damaged chute restores proper grass ejection angles and helps direct clippings safely away from the operator and bystanders. It does not alter blade geometry or cutting height; instead, it helps the deck discharge behave as originally designed.

• Helps prevent wet clump buildup under the deck
• Directs clippings to the side, reducing rear discharge tracking
• Maintains original clearance so the blade and deck interaction stays unchanged
• Improves safety by covering the discharge opening as intended

Who is this for: This Kerlista replacement chute is for homeowners and landscapers who own compatible Cub Cadet, MTD, Troy-Bilt or Craftsman tractors with 42" or 46" decks and need a durable, OEM-fit side discharge solution. Choose this part if your original chute is damaged, missing, or prematurely worn and you want a reliable, easy-to-install replacement that restores correct grass discharge and prolongs deck life.
