CUB CADET 490-501-F064 54" Deck Belt Fab XT2 XT1 ST54 SLX54 LX54 LT54 CMXGZAM501064 954-05025A 954-05025 754-05025A

What It Is

This is a replacement deck drive belt for 54-inch Cub Cadet lawn tractors. It transfers power from the engine pulley to the mower deck spindles, enabling blade rotation for cutting grass.

Fitment & Compatibility

Before buying, confirm your mower has a 54-inch stamped or fabricated deck (not 46" or 50"). This belt fits Cub Cadet models: XT1, XT2, ST54, SLX54, LX54, LT54, and Fab XT2. Cross-reference OEM part numbers: 490-501-F064, 954-05025A, 954-05025, 754-05025A, and CMXGZAM501064. Measure your old belt—this one is 1/2 inch wide and approximately 143.5 inches long (check actual length vs. your deck routing). It is an OEM Cub Cadet belt, not an aftermarket generic.

Key Things to Know

• Quality: OEM belt uses Kevlar-reinforced construction for longer life under heavy grass loads—less stretch and slipping than cheaper belts.
• Installation difficulty: Moderate. You’ll need to remove the deck, release tension from the idler pulley, and route the belt exactly per the deck diagram (take a photo before removal).
• Common gotcha: If your deck has a different belt routing (e.g., 3-blade vs. 2-blade spindle pattern), double-check the belt path—this belt is specifically for 3-spindle 54" decks.
• Only one review so far, but it’s a perfect 5.0—reflects typical OEM reliability.

Should You Buy It

If you own a compatible 54-inch Cub Cadet and want a direct OEM replacement that won’t snap mid-mow or cause deck vibration, this belt is the right choice. It’s pricier than aftermarket belts but avoids fit headaches and premature wear—worth it for heavy users or anyone wanting a guaranteed fit.
