731-07131 Lawn Mower Side Discharge Chute, Compatible with MTD, Cub Cad, Craftsman, Murray Hand-Pushed Lawn Mower, Also for Troy Bilt Mower TB110, TB130, TB200, TB230, TB240, etc, Replaces 731-7131

What It Is

This is a replacement side discharge chute designed to redirect grass clippings away from the cutting deck on hand-pushed (walk-behind) lawn mowers. It’s for mowers that originally came with a side discharge chute that has broken, cracked, or gone missing.

Fitment & Compatibility

• Brands: MTD, Cub Cadet, Craftsman, Murray, Troy-Bilt (specifically TB110, TB130, TB200, TB230, TB240 models).
• Deck size: Fits most 20–22 inch deck widths, but measure your existing chute mount width (typically 2.5–3 inches wide at the pivot point) to confirm.
• OEM reference: Replaces OEM part number 731-7131 (the “0” in 731-07131 is often a packaging/suffix variation).
• What to check before buying:
  • Verify your mower has a side discharge chute mounting bracket (not all models do).
  • Ensure the chute’s pivot hole aligns with the pin or bolt on your deck (usually a 5/16-inch or 3/8-inch hole).
  • If your mower has a mulching plug or bagger, the chute must be removed to install this.

Key Things to Know

• Quality: Made of durable plastic, but not impact-resistant. It will crack if you hit a rock or tree root. Expect 1–2 seasons of normal use.
• Installation: Tool-free – slides onto the deck’s pivot pin and snaps into place. No screws or bolts needed on most models.
• Common gotchas:
  • The chute may feel loose initially; a zip tie or small cotter pin can secure it if the locking tab wears out.
  • Not compatible with zero-turn or riding mowers – only hand-pushed models.
  • If your mower deck has a different pivot design (e.g., a spring-loaded latch), this chute won’t fit.

Should You Buy It

Yes, if you need a direct replacement for a broken or missing side discharge chute on a compatible MTD/Cub/Craftsman/Troy-Bilt push mower. It’s a cheap, easy fix that keeps clippings off your legs and away from the deck. Avoid if your mower uses a different mounting system or if you need a heavy-duty chute for rough terrain.
