What It Is

This is a 46-inch deck replacement belt (1/2" wide x 122" long) for Cub Cadet, MTD, and select Craftsman lawn tractors. It drives the mower blades via the deck spindle pulleys and is a direct replacement for OEM part numbers 754-04153, 754-04153A, 954-04153, 954-04153A, and 754-04118.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size: Your mower must have a 46-inch cutting deck (not 42" or 50").
2. Model number: Fits Cub Cadet LT1045, LT1046, L1046, and MTD 13AP605H755. Also fits some Craftsman GT5000 and LT1000 series with a 46" deck using the same belt routing.
3. Belt measurements: This belt is 1/2" wide and 122" outside circumference. Measure your old belt or check your owner’s manual—if it’s 1/2" x 122", this will work. OEM vs. aftermarket: this is an aftermarket belt; it matches OEM specs but may vary slightly in rubber compound or stiffness.

Key Things to Know

• Quality: At $12.99, this is a budget aftermarket belt. Expect shorter lifespan than OEM (1–2 seasons vs. 2–3 seasons with regular use). Check reviews for consistent tension and no premature cracking.
• Installation: Moderate difficulty—requires removing the deck, routing around pulleys, and a spring-loaded idler. Have a wrench and a belt tension tool handy. Watch a YouTube video for your exact model if unsure.
• Common gotcha: If your deck has a separate drive belt (for the transmission), this is only the deck blade belt. Don’t confuse them.
• Routing: Verify the belt path matches your deck diagram. Some Cub Cadet models use a different routing for this belt length—double-check the diagram under the deck or in your manual.

Should You Buy It

Buy this if you need a quick, low-cost replacement for a 46" Cub Cadet or MTD mower and don’t mind replacing it every year or two. It’s a decent budget option for light-to-moderate use, but if you mow heavy grass or want maximum durability, spend more on an OEM belt.
