What model tractor? What model loader? Do you have a rear remote valve installed that could be used as a valve/source? Could you get by with an electric splitter on the bucket circuit? Without details, the possibilities are numerous.
Sorry, it is on a TC35 16LA, and yes I have 1 remote valve at the back, So all I need is the steel lines that run along the loader arm and a set of hoses to go to the rear.
