1/2" X23 1/2" Drive Belt for Troy-Bilt 9201 GW-9201 20458-20463 Pony I and 20558 Super Pony Tillers

What It Is

This is a 1/2-inch-wide by 23.5-inch-long drive belt specifically designed for Troy-Bilt Pony I and Super Pony tillers. It transfers power from the engine pulley to the tine drive system, enabling forward tine rotation.

Fitment & Compatibility

Before buying, verify your tiller model number—this belt fits Troy-Bilt Pony I models 9201, GW-9201, 20458–20463, and Super Pony model 20558. It replaces OEM part 918-04683. Measure your existing belt length (center-to-center distance around pulleys) to confirm 23.5 inches is correct; a 1/2-inch width is standard for these models. This is an OEM replacement, not a generic aftermarket belt, so fit is exact for these specific Troy-Bilt tillers. Check your engine pulley and tine pulley condition—worn or bent pulleys can cause premature belt wear, even with a correct fit.

Key Things to Know

• Quality: OEM-grade construction with polyester cord and rubber compound; should last 2–3 seasons under normal use.
• Installation difficulty: Moderate—requires removing the belt cover and possibly loosening the engine mount bolts to slip the belt over the pulleys. No special tools needed beyond a socket set.
• Common gotcha: The belt must be routed correctly around the idler pulley and tensioner; check your owner’s manual diagram. Reversing the wrap direction causes slippage and rapid wear.
• Tension check: After installation, the belt should deflect about 1/2 inch with moderate thumb pressure. Too loose = slipping; too tight = bearing damage.

Should You Buy It

If you own a Troy-Bilt Pony I or Super Pony tiller listed above and need a direct OEM replacement for a worn or broken drive belt, this is the correct part at a fair price. It’s a no-guesswork buy for restoring tine drive function, but skip it if your tiller is a different model or if pulleys are damaged—fix those first.
