I would also recommend Donaldson. They're identical to most JD filters. I think they make/made some for them. Our JD 7810 has Donaldson fittings on the hydraulics and filters. Ma deere threw green paint over it, but if you look closely it says "Donaldson". Most truck places carry them but I order them online from an outfit in Utah that also carriers Baldwin and other brands too. They can normally get you about any filter that seems to be made. You can also plug in the JD OEM number and it will cross with any comparable filter they carry.
