Was going to post some more photos of the failed turbo yesterday but didn't get to it, and now it's quite a ways down the page, so I'm posting this as a new thread...

Tractor doesn't have a "through the hood" airstack.

The pre-cleaner under the hood got clogged with debris causing the engine to pull exhaust back through the aspirator and set the debris in the air cleaner on fire!

Even melted a hole in the compressor housing, thought I had a better photo of that, but you can see the hole in the housing in the ipper right area of THIS photo:
