Hello my son rolled our JD 1025r unto its side it continued to run for 15 to 20 seconds with a black smoke rolling out and then it shut off we were not able to shut it off with a key. I had my local John Deere dealer come pick it up to make sure it was okay or if it would need repairs. They had it for weeks almost 4 weeks and then told me that the engine was ruined it would need to be replaced. This all without doing a compression test or a leak down test to make any discernible diagnosis. They did replace the air filters...that's it. After what they told me was extensive troubleshooting, they did tell me that they ran it for a few minutes and black smoke was rolling out the muffler so they took the muffler off and ran it again for a while and then put the muffler back on and again black/blue smoke was coming out. They also told me that the cab would also need to be replaced as it was so badly damaged. Only damage I really saw to it was when the recker pulled it back up and the windshield broke, up until then it didn't appear that anything major had happened. I'm including a video / picture and would like to get feedback to see what your thoughts are on this engine.
