Not a snowball's chance in hell that loader would have lifted the end of that tree off that building. That looks like a pig hickory. If it is, at that size, we're looking at a tree that could easily weigh as much as that tractor does, or more.Since it's dead, Once it was trimmed down to this I would have seen if the loader would lift the end off the shop just a little and trim more off until maybe it cleared the barn.
Maybe even cut sections out of it to reduce weight more.
