This type of stump grinding challenge is pretty common. Birds drop Chinese elm seeds down beside the fence, Chinese elm begins to grow and nobody notices. The Elm grows around the steel fencing and becomes embedded. This becomes a more difficult job and creates extra stump grinding costs. The fencing steel breaks tree stump grinding teeth so we have to grind down underneath the fence to enable removal of the stump. We can do it and have done many of these problem jobs before.
