Riding Lawn Mower Tractor Aramid Drive Belt for Craftsman SPM201670500 MTD 754-0349 954-0349 Toro 112-0317 1/2" X 79"

What It Is

This is an aramid-reinforced drive belt (1/2" x 79") for riding lawn mowers and tractors. It transfers power from the engine pulley to the mower deck, commonly used on Craftsman, MTD, and Toro models that require a 79-inch belt.

Fitment & Compatibility

Before buying, verify these three things:

• Measure your old belt – Must be exactly 1/2" wide and 79" long. A 1/2" x 78" or 80" belt won’t fit properly.
• Cross-reference OEM part numbers – This belt replaces Craftsman SPM201670500, MTD 754-0349 and 954-0349, and Toro 112-0317. Check your owner’s manual or old belt for these numbers.
• Deck size – Typically fits 42" to 48" decks, but confirm your specific model. Not universal – compatibility varies by pulley spacing and deck design.

Key Things to Know

• Aramid construction – Stronger and more heat-resistant than standard rubber belts. Lasts longer under heavy use, especially on uneven terrain.
• Easy DIY install – No special tools required. Release deck tension, route belt per diagram, then re-tension. Expect 30-45 minutes.
• Common gotcha – Double-check belt routing before tensioning. Wrong routing causes slipping or premature wear. Take a photo of old belt before removal.
• Cheaper than OEM – At $14.99, it’s significantly less than OEM belts (often $25+). Performance is comparable for most homeowners.

Should You Buy It

Yes, if you need a reliable, durable replacement for a Craftsman, MTD, or Toro mower that uses a 1/2" x 79" belt and you want to save money over OEM. Skip it if you have a different belt length or need a deck-specific belt for a non-standard pulley setup.
