38" Deck Belt 954-0329A / Kevlar Cord / 5/8" x 69 3/8" - Compatible with MTD 754-0329A, 754-0433, 954-0433

What It Is

This is a 38-inch deck drive belt (5/8" wide, 69 3/8" long) with Kevlar cord reinforcement, designed to transfer power from the engine pulley to the mower blades on riding lawn mowers with a 38" stamped or fabricated deck. It’s a direct replacement for MTD/Parts Unlimited models using OEM numbers 954-0329A, 754-0329A, 754-0433, or 954-0433.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be exactly 38 inches (not 36" or 42"). Measure your deck width or check your model number.
• Belt dimensions: Confirm your current belt is 5/8" wide by 69 3/8" long (outside circumference). Any variation will cause slipping or improper tension.
• OEM cross-reference: This belt replaces MTD 954-0329A, 754-0329A, 754-0433, and 954-0433. If your mower uses one of those numbers, it fits. Common compatible brands: Cub Cadet, Troy-Bilt, MTD, Yard Machines, Huskee, and Bolens with a 38" deck from the 2000s–2010s. Check your owner’s manual or current belt for the exact OEM number.

Key Things to Know

• Kevlar cord gives longer life and better resistance to stretching under heavy load compared to standard polyester belts. Worth the slight price premium for frequent mowing.
• Installation difficulty: Moderate. You’ll need to remove the deck (or at least the belt cover) and use a wrench to release tension on the idler pulley. A belt installation tool or a long screwdriver helps.
• Common gotchas: The belt routing can be tricky—take a photo before removing the old belt. Also, this belt is directional; the printed arrows must point in the rotation direction. Incorrect routing causes rapid wear or thrown belts.
• Aftermarket vs OEM: This is an aftermarket belt but meets or exceeds OEM specs (Kevlar cord, same dimensions). It’s a solid budget alternative to MTD-branded belts, but if you need exact OEM fit for warranty or tight tolerances, buy the MTD original.

Should You Buy It

Buy this if you have a 38" deck MTD/Cub Cadet/Troy-Bilt riding mower needing a durable, affordable replacement for OEM 954-0329A or 754-0329A. The Kevlar cord adds longevity for heavy-use yards, and the price is fair for the quality. Skip if you need an exact OEM part for a newer mower under warranty, or if your deck is not 38 inches.
