MTD Deck/Drive Belt for Riding Mower/Tractors 38" Item#58991 Model#OEM-754-04062 UPC#037049948109

What It Is

This is a replacement drive belt for MTD riding mowers and tractors with a 38-inch cutting deck. It transfers engine power to the deck spindles and drive system.

Fitment & Compatibility

Before buying, verify your mower deck width is exactly 38 inches. This belt is OEM-equivalent to MTD part #754-04062 and fits most MTD, Cub Cadet, Troy-Bilt, and Yard Machines models with a 38-inch deck from the 1990s through 2010s. Cross-reference your model number on the MTD parts site or your owner’s manual—common fitments include MTD 13A-xxx, 13B-xxx, and 13C-xxx series. Do not rely on brand name alone; measure your old belt length (should be around 96-98 inches) and width (typically 1/2 inch). If your deck is 42 inches or larger, this belt will not fit.

Key Things to Buy

• Quality: This is a standard-replacement belt, not heavy-duty. It will wear faster under heavy or frequent use compared to Kevlar-reinforced options.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least release tension from the idler pulley. A belt routing diagram (often under the deck) is essential—take a photo before removing the old belt.
• Common gotchas:
  • Belt may be slightly tight on some pulleys—use a pry bar to gently work it onto the last pulley.
  • Check all idler pulleys for bearing wear while you have the belt off; a seized pulley can snap a new belt quickly.
  • If your deck has a PTO clutch, ensure the belt isn’t rubbing against the clutch housing.
• Durability: Expect 2-3 seasons of normal residential use. If you mow more than 2 acres weekly, consider a higher-grade belt.

Should You Buy It

Yes, if you need a direct, no-surprises replacement for a 38-inch MTD-compatible mower and don’t require heavy-duty performance. It’s a reliable, budget-friendly option for residential use, but skip it if you mow commercially or want a belt that lasts longer under tough conditions.
