I don't know how you have managed that.  I think everyone around here who had 12 bolt finals broke one or more at some point in time.  We broke one on our 16 bolt 895. 

I'm sure there are two places manufacturing steel replacements because breakage is virtually unheard of.  lol I have witnessed what happens when someone pulls on the front frame of a Versatile.  Fortunately just as an observer. 

We owned a Versatile.  It was a good tractor.  We never owned a Steiger, but there were many around the neighborhood, some owned by people I know well.  I don't recall any of them ever going broke because of the tractor they ran.  I do recall them working on manual transmissions a lot. I do not recall any ever breaking their frame.

We currently own a Steiger descendant.  Do not really have enough use on it to take a postion there.

You come across more then a little fanatical here when you act like well known problems do not exist.
