Troy-Bilt OEM Replaces Belt 1916657,954-04090,GW-1916657 1/2X25-1/2, FITS Models: Troy-Bilt Super Bronco, FRT, CRT, Bronco CRT and ProLine CRT roto-tillers

What It Is

This is a replacement drive belt (1/2-inch wide, 25-1/2 inches long) for Troy-Bilt Super Bronco, FRT, CRT, Bronco CRT, and ProLine CRT rear-tine roto-tillers. It transfers power from the engine to the tine drive system, enabling forward rotation and tilling action.

Fitment & Compatibility

Check these before buying:

• Model series: Fits Troy-Bill Super Bronco, FRT, CRT, Bronco CRT, and ProLine CRT roto-tillers only. Does not fit front-tine or non-Troy-Bilt tillers.
• Deck size: No deck involved – this is a tiller drive belt. Verify your tiller’s tine width (usually 17-24 inches) but belt length (25-1/2 inches) is the critical dimension.
• OEM vs aftermarket: This is a Troy-Bilt OEM replacement (part #1916657, 954-04090, GW-1916657). Aftermarket belts may differ in material quality or exact length.
• Measurement: Confirm existing belt reads 1/2" x 25-1/2" or cross-reference your model number with Troy-Bilt’s parts diagram.

Key Things to Know

• Quality: OEM belt ensures correct fit and durability; some aftermarket belts may slip or wear faster under heavy tilling.
• Installation difficulty: Moderate – requires removing the belt cover and possibly the tine shield. Have a wrench set and a belt tension tool handy.
• Common gotchas: Belt tension must be adjusted after installation (too loose = slipping, too tight = premature wear). Also check pulleys for debris or damage before installing.
• Lifespan: Expect 1-3 seasons depending on soil type and usage frequency. Replace if you see cracking, fraying, or glazing on the belt surface.

Should You Buy It

Buy this belt if you own one of the listed Troy-Bilt rear-tine tillers and need a direct OEM replacement with guaranteed fit. It’s priced competitively for an OEM part, but check your model’s exact belt length (25-1/2") to avoid mismatch. Good for DIY repairs, but if your pulleys are worn or misaligned, replace those first.
