MTD Replacement Part 42" Deck Sd Assembly with Wheel Brackets

What It Is

This is an MTD-branded replacement side discharge assembly for a 42-inch cutting deck, including the discharge chute and wheel brackets. It’s designed for lawn tractors or zero-turn mowers that use a side-discharge deck, directing clippings away from the cutting path.

Fitment & Compatibility

• Deck size: Must be a 42-inch MTD or MTD-compatible deck. Measure the deck width (blade tip to tip) to confirm.
• Model fit: Fits many MTD, Cub Cadet, Troy-Bilt, and Yard Machines models with a 42-inch deck. Check your mower’s model number (e.g., 13A-…, 13B-…) against MTD’s parts lookup tool.
• OEM vs aftermarket: This is OEM MTD, not a generic. Brackets and chute are pre-assembled—no need to swap hardware from your old assembly.
• Measurements: The assembly includes brackets that bolt to the deck’s side. Verify bolt hole spacing (typically 3–4 inches apart) and bracket shape matches your deck. If your old assembly uses a different bracket design, it won’t bolt up.
• Wheel compatibility: The included wheel brackets work with standard 4-inch or 5-inch deck wheels. If your deck uses a different wheel size, you’ll need separate wheels.

Key Things to Know

• Quality: Metal brackets, plastic chute. Durable for normal residential use, but the chute can crack if you hit obstacles or store it in direct sun.
• Installation difficulty: Moderate. You’ll need a socket set and possibly a pry bar to remove old bolts. Expect 30–60 minutes. No wiring or adjustments—just bolts and alignment.
• Common gotcha: The chute may not clear the deck’s underside on some older MTD decks. Test fit before tightening all bolts. Also, the wheel brackets might require different spacers if your deck has a reinforced edge.
• Price vs value: At ~$700, it’s a full assembly. If your chute is fine but brackets are broken, you can buy just the bracket kit for ~$50–$100.

Should You Buy It

Buy this if your MTD 42-inch deck’s side discharge assembly is rusted, bent, or missing, and you want a direct OEM replacement without hunting for individual parts. It’s right for owners of MTD, Cub Cadet, or Troy-Bilt tractors who need a bolt-on fix and aren’t on a tight budget. If your deck is older or non-MTD, check measurements first—or you’ll be returning a $700 part.
