JD does not offer a factory 3rd function valve for the 1-series. I believe they do offer a 3rd SCV on the rear. You could always run hoses up front from the rear 3rd SCV or a more elegant solution is to use one of the diverter kits from Artillian or KBOGH.When building either one or two series I see no option for the addition of a third function valve. Are provisions already in place so you can run a grapple for instance or is add on that the dealer would have to do?
Teas us with. H. J. has a video on install but don't give us a link. :nunu:on my 1025 I have a Artillion Dirveter Kit that works well. On my 2038 I have a WR Long 3rd svc kit that I haven't installed yet. Homestead Joe has a video on youtube about installing one.
