I can't remember the details, so I would direct you to do some searching here and in the NH threads, but I remember a gentleman for New Hampshire having his NH crack like this. He was carrying a very large snow-blower while scraping his drive with the loader. I believe NH helped him with the repair (a new block I think), and I think there may have been an issue with loose fasteners. The prognosis here on TBN started as a tractor fault and then operator error I think. Maybe that member can chime in and give the actual facts instead of my hazy and possibly distorted memories...
Unfortunately, this is always going to be possible when equipment is hard mounted to cast iron components. Impact shock is easily transmitted and cast iron is very brittle. I see many manufactures are going to the post mount loaders that do not have any linkage to the front of the tractor. I wonder if this allows the loader mounts to flex a little and absorb the damaging shock?
You mentioned digging a culvert with the machine and your backhoe is subframe mounted. Did the you snag something while digging enough to raise the frontend? Did it break loose and let the frontend of the tractor fall? I seem to remember someone stating that this is a likely cause of tractor /backhoe breakage.
