Stens OEM Replacement Belt 266-155 for Cub Cadet 954-04250

What It Is

The Stens OEM Replacement Belt 266-155 is a drive belt designed for Cub Cadet lawn tractors, specifically replacing OEM part 954-04250. It transfers power from the engine to the mower deck blades, making it essential for cutting performance.

Fitment & Compatibility

Before buying, check your Cub Cadet model number (usually on a sticker under the seat or on the frame). This belt fits select Cub Cadet LT and RZT series tractors with 42-inch, 46-inch, or 50-inch decks—verify your deck size. Compare the belt length (measured in inches around the pulleys) to your old belt; the 266-155 is a direct OEM replacement, so it matches Cub Cadet’s 954-04250 specs. Aftermarket belts may vary, but this Stens part is a reliable substitute. Also confirm your deck’s belt routing diagram (found in your manual or online) to ensure the belt path matches.

Key Things to Buy

• Quality: Stens is a reputable aftermarket brand; this belt is made from reinforced rubber for durability, but it may not last as long as a genuine Cub Cadet belt in heavy use.
• Installation Difficulty: Moderate—requires removing the deck or accessing the belt from underneath. You’ll need basic tools (socket set, flathead screwdriver) and about 30-60 minutes. Watch for belt tensioner spring tension.
• Common Gotchas: Double-check belt length (measure old belt end-to-end, not around pulleys). On some models, you may need to remove blades or pulleys for access. Ensure belt routing is correct—using the wrong path can cause slipping or premature wear.
• Price vs. OEM: At $19.15, it’s often cheaper than Cub Cadet’s genuine belt (which can be $25-35), but check your local dealer for availability.

Should You Buy It

Yes, if you have a compatible Cub Cadet model and want a cost-effective replacement without sacrificing reliability. It’s ideal for DIY homeowners who need a direct fit and don’t mind a slightly shorter lifespan than OEM. For commercial use or if you’re unsure of fitment, stick with the genuine Cub Cadet belt to avoid frequent replacements.
