My first JD had an 8A BH. JD970, 4x4 with model 80 FEL. It was a good attachment and forever sold me on continuing to own a backhoe!I have a 4120 JD and was wondering if anyone knew if an 8A backhoe would fit? It looks like the backhoe has quite a heavy frame with it. Would it be easy to take off and on?
