CUB CADET Deck Chute Assembly 631-05191A — OEM Discharge Chute, Direct-Fit for Tractors & ZTRs

The CUB CADET 631-05191A deck chute assembly is an OEM discharge chute that replaces several prior part numbers to restore safe, efficient grass and clippings ejection on compatible Cub Cadet riding mowers and zero-turns.

How does this OEM replacement compare to aftermarket chutes?

OEM chutes are manufactured to the original specifications for fit, mounting points and material grade, which reduces installation adjustments and fitment issues. Choosing an OEM part simplifies the repair and preserves the mower’s original performance characteristics.

• Built to match Cub Cadet’s original dimensions and mounting features.
• Material and thickness align with factory tolerances for durability.
• Direct replacement that usually requires no modification or adapters.

What should I check before installing the chute assembly?

Prepare by inspecting the cutting deck and surrounding hardware so installation is straightforward and secure. Replace any corroded fasteners or damaged mounting brackets to ensure the new chute seats properly and remains stable during operation.

• Verify the mower model and part number against your owners manual or the existing chute label.
• Inspect deck edges, spindles and brackets for wear or damage that could affect fit.
• Have the correct fasteners on hand—OEM parts often reuse factory bolts and clips.

What benefits will I notice after replacing the chute assembly?

Installing a properly fitting discharge chute restores the intended clippings path, improves safety by directing debris away from the operator and helps the mower distribute clippings evenly across the lawn. It can also reduce the chance of grass buildup under the deck.

• Cleaner discharge pattern for a neater cut and reduced clogging.
• Improved operator safety by shielding flying debris.
• Easier maintenance with a secure, correct-fit component.
