I just bought a L225DT kubota and it has a three point hitch,can i either buy a back hoe to fit my kubota tractor or would it be better and cheaper to build one ?
Building a backhoe attachment would take time and some very good metal fabrication skills. All those bushings and pins need to line up plus buying all the metal, hoses, etc. is not cheap, either.
If you use the search tool and search the build it yourself forum and maybe the attachments forum, you'll find lots of useful information about your question.
