8TEN Deck Drive Belt for Cub Cadet MTD Troy Bilt 33 inch CC760 CC760ES TBWC33XP 754-04139 954-04139

What It Is

This 8TEN deck drive belt transfers power from the engine pulley to the spindle blades on select 33-inch cutting decks. It’s designed for residential zero-turn and walk-behind mowers from Cub Cadet, MTD, and Troy-Bilt, specifically models with a 33-inch deck and a 2-blade spindle system.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 33 inches (measured blade tip to blade tip) and that it uses a 2-blade spindle setup. This belt replaces OEM part numbers 754-04139 and 954-04139. It fits Cub Cadet CC760, CC760ES, and Troy-Bilt TBWC33XP, plus many MTD-built models with those same deck specs. Measure your existing belt length (should be roughly 95.5 inches) and width (typically 1/2 inch). If your mower uses a different OEM number or has a 42-inch or 46-inch deck, this belt won’t work.

Key Things to Know

• Quality vs. OEM: 8TEN is an aftermarket brand. Expect similar durability to OEM for residential use, but may wear faster under heavy commercial conditions.
• Installation difficulty: Moderate—requires removing the deck and routing the belt around pulleys and tensioner. Check your manual for the specific belt path diagram.
• Common gotcha: The belt can be tight to install, especially if the tensioner spring is strong. Use a wrench to relieve tension, never force the belt over a pulley edge.
• No installation hardware included: You’ll need your own tools (socket set, pliers) and possibly a belt installation tool for stubborn tensioners.

Should You Buy It

If you own a compatible 33-inch Cub Cadet, MTD, or Troy-Bilt mower and need a reliable, budget-friendly replacement for light-to-moderate residential use, this belt is a solid choice. It’s not ideal for daily commercial mowing or if you require OEM warranty matching.
