954-04001A 754-04001A Lawn Mower Drive Belt 5/8" x 69" for MTD 754-04001 954-04001,for Husqvarna 578453619,for Murray 37X112 37X112MA | Aramid Cord

What It Is

This is a 5/8" wide, 69" long drive belt (Aramid cord construction) that transfers power from the engine pulley to the mower deck blades. It’s designed for certain MTD, Husqvarna, and Murray lawn tractors with 42" to 46" decks.

Fitment & Compatibility

• Measure your old belt first: Must be exactly 5/8" wide and 69" long (round, not flat). If your old belt measures differently, this won’t fit.
• Cross-reference OEM numbers: Listed for MTD 754-04001 / 954-04001, Husqvarna 578453619, and Murray 37X112 / 37X112MA. Verify your mower’s original part number matches one of these—don’t rely on brand alone.
• Check deck size: Typically fits 42" to 46" cutting decks, but not all models—confirm your deck size in the owner’s manual or parts diagram.
• Aftermarket vs OEM: This is an aftermarket replacement with Aramid cord (stronger than standard rubber). It’s a direct fit for the OEM numbers listed, but not a universal “one-size-fits-all” belt.

Key Things to Know

• Aramid cord = longer life: More resistant to heat and stretching than standard rubber belts. Good for heavy or frequent use.
• Installation is moderate: You’ll need to remove the deck or at least the belt guard. Take photos before removing the old belt to avoid routing errors.
• Check pulley condition: Worn or rusty pulleys will shred any new belt quickly. Inspect and clean/replace pulleys before installing.
• No tension adjustment: Most MTD/Husqvarna decks use a spring-loaded idler pulley—the belt self-tensions. If the belt is too loose after install, the routing is wrong or the idler is stuck.

Should You Buy It

If your mower is an MTD, Husqvarna, or Murray with a 42-46" deck and the OEM belt number matches, this is a solid upgrade over standard rubber belts—especially for rough terrain or heavy grass. The Aramid cord adds real durability for the price. Skip it if your belt measures differently or you need an exact OEM match for warranty purposes.
