Ok, so did the block split appart or did it rip bolts holding the crank housing to the cylinders? seems an odd place to have a failure.
You can see the block flying off at some point in the video. It looks like it ends up on the ground behind the right rear tire. That is full-on insane. It looks like it took a couple of pistons and rods with it.
looks like a straight-6. and looks like the block broke just above where the main bearing bolts end. so it just threw the rest of the block right up off the top. insanity!!!
Often times, tractors have to put many large bolts through the exhaust to prevent turbine wheels from seriously injuring people. The pressure ratios they run are insane, and are hell on components, obviously. That motor was anything but stock too. Those aluminum connecting rods were quite substantial.
