Deutz will be more expensive to repair i rekon, they may excellent engines, the 2 cylinder ones used to rattle around like crazy, but the 3 cylinder ones were a lot better.I think most of the older ones used Perkins diesels so there must have been a very brief time that the Kubota was used. Unlike Bobcat, ASV doesn't seem to have a website that details the historical changes through the years. Makes it hard to research used machines.
