711027 Ariens Lawn Mower - Overview

This 21-inch mulching plug is used on walk-behind lawn mowers to block the rear discharge opening and create a closed mulching chamber. By keeping clippings under the deck longer, it allows grass to be cut into finer pieces that are returned to the lawn as natural fertilizer. It’s a direct-fit accessory for converting a mower to mulching mode and a straightforward replacement for worn or missing mulch plugs.
