Hard to say, since I wasn't there. When I use to board, it was fairly common for one particular horse to cast herself- and of course, no one else there but me

I had to pull her away from the wall many times using ropes.
There were also a few other horses that I had to pull away by myself. I'm 5'8", use to body build, but I'm still just one woman pulling TB's and QH's by myself. If I could do that by myself, I have a hard time imagining that a man would need a back hoe to pull a pony. Sounds like she was stuck somehow and things should've been moved before pulling her away
