What It Is

This is a replacement deck belt for 42-inch cutting decks on Troy-Bilt Bronco and Pony riding mowers, as well as select MTD models. It drives the mower blades from the engine pulley and is built with aramid cord for added strength and reduced stretch.

Fitment & Compatibility

Before buying, confirm your belt measures exactly 1/2" wide by 96-1/2" long (use a tape measure on your old belt, not the deck). This belt replaces OEM part numbers 954-04060B, 954-04060, 754-04060B, 754-04060, and 754-05056. It fits Troy-Bilt Bronco (model series 13A, 13B, 13W) and Pony (model series 13A, 13W) with 42-inch fabricated or stamped decks, plus many MTD 42-inch decks from the early 2000s onward. If your mower uses a different deck size (38", 46", 50"), this belt will not work.

Key Things to Know

• Quality: Aramid cord is more durable than standard rubber belts, resisting heat and stretching better under heavy use.
• Installation difficulty: Moderate. You’ll need to remove the deck, release the idler pulley tension, and route the belt around all pulleys per your deck diagram. A belt routing sticker is often under the deck.
• Common gotcha: Verify your deck has the correct pulley configuration. Some 42-inch decks use a different belt length (e.g., 96-3/4") if pulleys have been replaced or the deck is a later version. Measure twice.
• Break-in: Expect slight initial stretch; re-tension after the first 1-2 hours of use if your belt tensioner allows adjustment.

Should You Buy It

If you own a Troy-Bilt Bronco or Pony with a 42-inch deck and need a reliable, budget-friendly replacement that matches OEM specs, this belt is a solid choice. It’s not for other brands (John Deere, Craftsman) or different deck sizes, but for the listed models, it offers good value and durability.
