731-07131 987-02516A Side Discharge Chute and Hinged Mulching Plug Compatible with MTD Craftsman Lawn Mower. for TB110, TB130, TB200, TB230. Replace 731-7131 987-02516

What It Is

This kit includes a side discharge chute and a hinged mulching plug designed for MTD, Craftsman, and Troy-Bilt walk-behind lawn mowers, specifically models like the TB110, TB130, TB200, and TB230. It lets you switch between side-discharge and mulching modes without tools.

Fitment & Compatibility

Before buying, confirm your mower’s deck size (typically 21-inch or 22-inch on these models) and check your model number against the compatible list: TB110, TB130, TB200, TB230, or any MTD/Craftsman with a 21-22” deck using the same mounting holes. This is an aftermarket replacement for OEM parts 731-07131, 987-02516A, 731-7131, and 987-02516. Measure the chute mounting slot width (approx. 1.5”) and pin hole spacing (approx. 3.5”) on your deck—if it matches, it fits. Not compatible with electric or zero-turn mowers.

Key Things to Know

• Build quality: The plastic is durable but can crack if overtightened; hand-tighten only.
• Installation: Takes about 5 minutes—no tools needed for the mulching plug (hinged design clips in), but the side chute may require a retaining pin or cotter pin (check if yours is missing).
• Common gotcha: The mulching plug hinge can loosen over time; a dab of thread locker on the hinge pin helps.
• Performance: The mulching plug works best with sharp blades and dry grass; wet grass may clog.

Should You Buy It

If you have a compatible MTD/Craftsman walk-behind mower and want an affordable, no-tool way to switch between side discharge and mulching, this kit is a solid buy. It’s well-rated and cheaper than OEM, but skip it if your deck size or mounting holes don’t match exactly.
