Foifatt 631-05195A Mulch Plug Replacement for 42 and 46 Inch Lawn Mowers

Overview

The Foifatt 631-05195A mulch plug replacement is designed to restore the mulch deck on select 42 and 46 inch lawn tractors. This direct replacement part aims to support consistent mulch coverage and deck performance on compatible models, offering a practical option when the original plug shows signs of wear or has become difficult to secure.

Crafted to fit a range of popular mower lines, this plug aligns with the deck geometry of the listed units and helps maintain proper mulching flow during mowing sessions. While not every deck will be compatible, the part is engineered to work with many 42 and 46 inch configurations found in the field, helping you keep maintenance tasks straightforward and efficient.

What it fits and how to check compatibility

• Replacement part number: 631-05195A (also listed as 631-05195).
• Compatible models include 19A30046100 (42 inch), 19A30047100 (46 inch), 19A30055100 (42 inch), 19A70041 (42 inch), and 19B30005 (46 inch).
• Works with mower families that are 2012 and newer, spanning brands commonly used with MTD built decks.

Important compatibility notes

• The mulch plug does not fit all two blade 42 or 46 inch decks; model numbers under the seat must start with 247 for this to apply to MTD built tractors. This is not designed for craftsman decks that start with 917, and it will not work on a three blade deck.
• The part is not sponsored or endorsed by the brands listed as compatible, including MTD and Cub Cadet, but is designed to fit the specified models when the deck configuration matches.

Practical use and expectations

In everyday lawn care, replacing a worn mulch plug can help maintain consistent deck coverage and mulching performance. The Foifatt plug is a compact, replaceable component you can install with standard tools during routine maintenance, offering a straightforward upgrade path without larger component changes.

While the replacement may contribute to smoother operation on compatible decks, outcomes can vary by mower condition, deck model, and maintenance history. Consider this part as a potential enhancement option rather than a guaranteed performance change.
