731-07131 987-02516A Side Discharge Chute & Hinged Mulch Plug Compatible with MTD Craftsman 21" Hand Pushed Lawn Mower, Fits TB110, TB130, TB200, TB230

What It Is

This is a two-piece accessory set that includes a side discharge chute and a hinged mulch plug for 21-inch hand-pushed MTD/Craftsman lawn mowers. It lets you switch between side-discharging clippings or mulching them without tools.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch cutting deck—this part only fits that size. It’s designed for MTD-built Craftsman models, specifically the TB110, TB130, TB200, and TB230 series. Also fits many similar MTD/Craftsman push mowers with the same deck shape. Check your mower’s model number (stamped on the deck or under the rear flap) against the OEM part numbers 731-07131 and 987-02516A. If your mower uses a different chute or plug design (e.g., older or non-MTD decks), it won’t work. Measure the discharge opening width and hinge pin location if possible.

Key Things to Know

• Quality: Molded plastic is durable but can crack if overtightened or hit hard. The hinge on the mulch plug is spring-loaded and holds position well.
• Installation: Tool-free—slides into the deck opening and locks with a tab or pin. Takes under 5 minutes. No modification needed.
• Common gotcha: The chute may not seal perfectly on decks with heavy rust or warping. Inspect your deck’s mounting area first.
• Mulch plug note: The hinged design lets you open it to discharge without removing the plug entirely—handy for switching modes mid-mow.

Should You Buy It

Buy this if you own a compatible 21-inch MTD/Craftsman push mower and want an affordable, tool-free way to switch between side discharge and mulching. It’s a direct OEM-style replacement for worn or missing parts, and the 4.6-star rating reflects reliable fit and function. Avoid if your deck is damaged or you need a universal fit for a different brand.
