This is a very common crack to find on the Bobcat 873 loader arm, I am pointing it out because it is in a very strange place, people don't usually look for cracks in this area. I have found other loader arms in Bobcat dealer yards metal bins completely broken in half at this point. These loader arm cracks are located right at the rear ROPS corner post on a F series 873.

I think the G-series 873 got some reinforcements -- can anyone confirm?
