Lawn Mower 731-07486 Side Discharge Chute for Most 21" Hand Pushed Lawn Mower Compatible with Craftsman Columbia Huskee Troy Bilt Yard-Man MTD TB110, TB130, TB220, TB230 & 11A, 12A Series Mowers

What It Is

This side discharge chute (part 731-07486) directs grass clippings out the right side of your mower deck, preventing clogs and ensuring even dispersal. It’s designed for most 21-inch hand-pushed mowers from Craftsman, Columbia, Huskee, Troy-Bilt, Yard-Man, and MTD, including popular models like TB110, TB130, TB220, TB230, and 11A/12A series.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Only fits 21-inch cutting decks. Measure your deck width (blade tip to tip) to confirm.
• Model number: Verify your mower’s model number (starts with 11A or 12A for MTD-built machines) matches the listed series. For Craftsman, look for model numbers like 917 or 247 prefixes.
• Mounting style: This chute uses a single spring-loaded latch pin. Ensure your deck has the corresponding mounting bracket (a small metal tab with a hole near the discharge opening). It’s an aftermarket replacement for OEM part 731-07486, so it should match original fit.

Key Things to Know

• Quality: Made of durable, UV-resistant plastic. Holds up well to regular use but can crack if hit against curbs or rocks. Rated 4.6/5 from 950 reviews.
• Installation: Tool-free—align the chute with the bracket, push the latch pin through, and secure. Takes under 2 minutes.
• Common gotchas: The latch pin can be stiff initially; apply a little grease if needed. Also, some users report a slight gap on non-MTD decks (e.g., older Craftsman models), which may cause minor clumping in wet grass.
• Not universal: Won’t fit 22-inch decks or mowers with offset discharge openings (e.g., Honda, Toro, or John Deere).

Should You Buy It

If you own a 21-inch MTD, Craftsman, or Troy-Bilt push mower and need a direct, affordable replacement for a broken or missing chute, this is a solid choice. It’s easy to install, widely compatible, and backed by strong reviews. Skip it if your mower isn’t on the compatibility list or if you need a chute for a non-standard deck design.
