Additional Information

The MTD Lawn Tractor Mulch Cover Assembly (part number 631-04463) blocks the side discharge chute on the mower deck, allowing clippings to circulate under the deck and be cut into finer pieces. These clippings then fall back into the lawn as mulch, promoting healthy grass growth and reducing the need for bagging.

If your lawn tractor is leaving clumps of clippings or discharging unevenly, a missing or damaged mulch cover may be the cause. Replacing the mulch cover can improve mowing efficiency and deliver a cleaner, more even cut.

Before installing, park the tractor on a level surface and disconnect the spark plug wire. Align the mulch cover with the chute opening and press it firmly into place. No tools are required, but take care to avoid sharp edges during handling. Refer to your owner?s manual to confirm fitment and installation details.

Maintaining a functional mulch cover helps keep your lawn looking its best while reducing cleanup time after mowing.
