It's really hard to diagnose without all the facts. But assuming you didn't run it dry of oil and it just won't start now and your oil light is on. I would suspect you may have a faulty oil level sending unit. In some cases if the oil light is on the tractor won't start this is a safety issue so you won't hurt the engine. This is only my assumption, I am not a John Deere mechanic by any means but you could ask a John Deere mechanic about this and they could tell you for sure. Hope this helps. Thanks for watching!
