John Deere OEM Drive Belt Mower Deck 41 48 120 140 210 212 214 216 300 314 316 317 318 322 330 332 420 430 M82718

What It Is

This is the OEM drive belt (M82718) for the mower deck on a wide range of vintage and compact John Deere lawn and garden tractors. It transfers power from the engine pulley to the deck spindles, enabling blade rotation.

Fitment & Compatibility

Before buying, verify three things:

1. Deck size & type: Fits 38", 41", 48", 50", 54", 60" decks on models including 41, 48, 120, 140, 210, 212, 214, 216, 300, 314, 316, 317, 318, 322, 330, 332, 420, 430. Not all decks on these models use this belt—check your deck’s part number.
2. OEM vs aftermarket: This is genuine John Deere. Aftermarket belts may use a different part number or length—cross-reference your current belt’s stamped numbers.
3. Physical measurement: The belt is approximately 1/2" wide, 129.5" long (outside circumference). Measure your old belt end-to-end (not looped) to confirm.

Pro tip: Search “John Deere M82718 belt diagram” for your specific model to confirm routing before buying.

Key Things to Do

• Quality: OEM belts last significantly longer than budget options. This belt is reinforced for heavy use and resists stretching.
• Installation difficulty: Moderate. Requires removing the deck, releasing tension from the idler pulley, and routing around all pulleys correctly. A diagram helps.
• Common gotchas:
  • Reversing belt direction (arrows on belt indicate rotation) can cause premature wear.
  • Worn pulleys or a bad tensioner will shred any new belt quickly—inspect them before installing.
  • Belt is not reversible; install with the printed side facing out.

Should You Buy It

Yes, if you own one of the listed John Deere tractors and want a reliable, drop-in replacement with no guesswork. The price is fair for OEM quality, and the high rating reflects consistent durability. Avoid if you have a non-Deere deck or need a belt for a different application.
