OEM Replacement 954-04325 Belt for MTD CUB Cadet 754-04325 RZT46 TZT-L46 RZT-S46- Durable, Aramid Cord Belt

What It Is

The OEM Replacement 954-04325 Belt is a drive belt designed for MTD and Cub Cadet zero-turn mowers, specifically models like the RZT46, TZT-L46, and RZT-S46. It transfers power from the engine to the mower deck blades.

Fitment & Compatibility

Before buying, confirm your mower’s model number and deck size (typically 46 inches for these models). This belt replaces OEM part numbers 954-04325 and 754-04325. It is a direct OEM replacement, not a universal aftermarket belt, so it’s built to original specs. Measure your old belt’s length and width (common for this part: 1/2” wide, ~100” long) to double-check. Only buy if your mower is listed in the compatible models above—using it on other decks may cause slipping or damage.

Key Things to Know

• Quality: Made with aramid cord for added durability and reduced stretching compared to standard rubber belts. Expect longer life under heavy use.
• Installation: Moderate difficulty—requires removing the mower deck and routing the belt around pulleys. A diagram or video for your specific model helps.
• Common gotcha: The belt must be tensioned correctly after installation; too loose causes slipping, too tight wears pulleys. Check your manual for tension specs.
• Fitment note: Not compatible with non-MTD/Cub Cadet decks or older models without the exact 46-inch deck. Verify your deck size and model year.

Should You Buy It

If you own an MTD or Cub Cadet RZT46, TZT-L46, or RZT-S46 zero-turn mower and need a reliable, OEM-spec drive belt, this is a solid choice. The aramid cord adds longevity for frequent mowing, and the price is reasonable for a branded replacement. Avoid it if your mower uses a different deck size or brand—stick to your model’s specific belt number.
