Step-by-Step John Deere STX38 Yellow Deck Belt Replacement
Removing the Old Belt
1. Lift the cutting deck and secure it with a jack or a piece of wood to keep it in place.
2. Using a socket wrench and ratchet, remove the belt tension pulley bolt. You'll find it on the right side of the deck, near the engine.

Installing the New Belt
1. Inspect the new belt to ensure it's the correct one for your John Deere STX38. It should have the part number 86156 stamped on it.
2. Route the new belt around the pulleys, following the same path as the old belt. Ensure it's properly seated on each pulley.
3. Reinstall the belt tension pulley bolt and tighten it using the socket wrench and ratchet. Be careful not to overtighten, as this can damage the belt and pulleys.
4. Lower the cutting deck and start the engine to ensure the new belt is running smoothly. If everything is working correctly, you're all set!
