Leego Deck Belt Compatible with Cub Cadet MTD Troy-Bilt 754-0498, 954-0498, MTD42 Deck G Assembly, Troy Bilt 42" Assembly G, Bronco, Super Bronco With42 Mower Decks

What It Is

This is an aftermarket replacement deck belt (part numbers 754-0498 / 954-0498) designed to drive the blades on 42-inch mower decks used by Cub Cadet, MTD, and Troy-Bilt riding mowers—specifically the MTD42 Deck G Assembly and Troy Bilt 42" Assembly G. It fits models like the Bronco and Super Bronco with 42" fabricated or stamped decks.

Fitment & Compatibility

Before buying, check these three things:

• Deck assembly: Your mower must use the “MTD42 Deck G Assembly” or “Troy Bilt 42” Assembly G” – not all 42” decks use this belt. Look for a label on the deck or in your manual.
• OEM cross-reference: This belt replaces OEM part numbers 754-0498 and 954-0498. If your original belt has a different number (e.g., 754-0498A or 954-0498B), verify length and width—minor revisions may affect fit.
• Measurements: Belt is 1/2" wide by 96.5" long (approx.). Measure your old belt end-to-end (flat, not twisted) to confirm. If you’re off by even 1/2", it won’t tension properly.

Key Things to Know

• Quality vs OEM: This is an unbranded aftermarket belt. It’s thinner and less durable than a genuine Cub Cadet/MTD belt—expect shorter life (1-2 seasons vs 3-4 seasons).
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt cover, release the idler pulley tension, and route around all pulleys per your deck diagram. A belt tool or pry bar helps.
• Common gotcha: The belt may appear to fit but rub against the deck frame if your idler pulley or spindle is worn. Check pulleys for wobble or damage before installing.
• Tension check: After installing, run the deck at full throttle for 30 seconds, then re-check belt tracking. Slight adjustment of the idler arm may be needed.

Should You Buy It

If you need a quick, cheap replacement to finish mowing season and you’re comfortable with a slightly shorter lifespan, this belt works. For heavy-duty use, frequent mowing, or uneven terrain, spend more on an OEM belt—the extra cost (~$15–20) buys better durability and fewer mid-season failures.
