Yes it will survive and most of us prune our trees that low at planting. But you don't have a choice so just cut if off clean and it will grow back very fast.

The Fruitnut

Fruitnut, he said the bull broke the tree off 2 inches above the graft.

kossetx, growth coming from below the soil will be seedling tree. Not good for eating. If growth starts above the graft, it will be Moonglow pear. Select one vigorous shoot to train into a new tree. Fruitnut is right, the new tree will grow very fast with already well developed roots.

Never mind, my mistake. Cut it off clean like fruitnut stated. Pears tend to grow straight up. Wrap stiff wire around the trunk to train new scaffold branch angles 60 degrees outward from the trunk.
