Cub Cadet Mulch Plug Assembly

This part is designed specifically for Cub Cadet and MTD lawn mowers. Before purchasing, verify your mower's model number against the manufacturer's parts list to ensure it matches the 631-05195A specification.

Installing this plug seals the discharge chute, which forces grass clippings to circulate within the deck. This creates a finer cut and returns essential nutrients back into your soil, acting as a natural fertilizer for a healthier lawn.

No, it is designed for straightforward installation. It typically slides into the discharge chute area without requiring specialized tools, though you should ensure your mower deck is clean and free of debris before attaching it.

While this plug will physically fit your deck, for the best mulching results, we recommend pairing it with dedicated mulching blades. Standard high-lift blades may not chop the grass finely enough to get the full benefit of the mulching system.

Aside from keeping it clean, it requires very little maintenance. Periodically check that the plug is securely seated and free of built-up grass clumps to ensure optimal airflow and cutting performance.
