The original Citation needed was in my opinion requesting proof that it was dangerous for the bucket to be reversed on a backhoe not that is was actually possible Most of the paragraph was in fact written as a part of some Vandalism which was not completely removed I rewrote the paragraph and provided a photo showing the bucket reversed on a machine makes sense to me that this should be proof enough I can provide a cite but it would be from a company who build the hitches and this might be considered advertising Your call
