If you’re experiencing problems with your John Deere 9650 STS Combine Harvester, here are some troubleshooting steps to try:

  1. Check the engine air filter. If it’s dirty or if the cover isn’t fitting properly, the air flow into the engine may be impaired and cause trouble. Replace the air filter if needed.
  2. Make sure all of the spark plugs are firing correctly. A bad spark plug can cause misfires and other problems with the engine. Check each plugg when you do your annual tune-up.
  3. Check for clogged oil filters or leaking seals on the engine block or crankshaft pulley wheel. A build-up of debris over time can cause these problems, and they will need to be fixed in order for the combine to operate properly.
  4. Make sure that all moving parts on the combine are lubricated and free from debris buildup. This includes gears, shafts, bearings, and couplers between different parts of the machine.
