Know Before You Order

Some orders ship faster than others

We stock tens of thousands of parts in our warehouse, and most in-stock orders ship within 24 business hours. Because we specialize in hard-to-find tool parts, some items are sourced directly from the manufacturer after your order is placed and may require 10–14 business days before shipment. We believe in being transparent about timelines so you know what to expect before ordering. If timing is critical, please contact with your part number for an estimated delivery timeframe.

Why does M&M Tool Parts offer parts other companies don’t?

As a family-owned business, we’ve built long-standing relationships with trusted manufacturers across the industry. These partnerships allow us to source specialty parts that are often unavailable through larger retailers or online marketplaces. In many cases, M&M Tool Parts provides one of the few reliable ways to obtain these components — and we work hard to get them to you as quickly as possible.

What should I expect after placing my order?

Our team begins processing orders immediately. If your item is stocked locally, you’ll typically receive tracking information within 24 business hours. For manufacturer-sourced items, we coordinate directly with vendors to secure and ship your order as efficiently as possible. We understand downtime is frustrating, and we sincerely appreciate your patience while we help source parts that can often be difficult to find elsewhere.

Read More

The Milwaukee 31-44-0147 Mulch Plug is a genuine OEM replacement part designed for select Milwaukee M18 FUEL 21-inch Self-Propelled Dual Battery Lawn Mowers. The plug closes the mower's discharge opening to enable mulching operation, allowing grass clippings to remain inside the cutting deck for additional processing before being returned to the lawn.

Product Specifications

Part Number: 31-44-0147
Part Type: Mulch Plug
Manufacturer: Milwaukee Tool
Application: 21-Inch Self-Propelled Lawn Mower
Function: Enables Mulching Mode
Condition: Genuine OEM Milwaukee Replacement Part

Mower Compatibility

The Milwaukee 31-44-0147 Mulch Plug is designed for select Milwaukee M18 FUEL 21-inch Self-Propelled Dual Battery Lawn Mowers, including:

Compatible Model: Milwaukee 2823-20
Compatible Serial Configurations: M44A, M44B

Compatibility may vary by mower serial number and production revision. Verify your specific model, serial configuration, and applicable Milwaukee parts diagram before ordering to ensure proper fitment.

Part Function

The mulch plug closes the mower's discharge opening when operating in mulching mode. With the discharge path closed, grass clippings remain inside the cutting deck where the rotating blade can cut them into smaller pieces before they fall back onto the lawn.

Benefits of Mulching

Mulching eliminates the need to collect and dispose of grass clippings during many mowing applications. Finely cut clippings are returned to the lawn, where they naturally decompose and return organic material and nutrients to the soil.

Secure Fit

The 31-44-0147 is shaped specifically for the compatible Milwaukee mower housing and uses integrated retention features to remain securely positioned during operation. Proper installation helps keep the discharge opening closed while the mower is being used in mulching mode.

When to Replace the Mulch Plug

Replacement may be necessary if the original mulch plug is lost, cracked, broken, or no longer remains securely installed in the mower. A damaged or improperly fitting plug can prevent the mower from operating effectively in its intended mulching configuration.
