Does an IH686 have open center hydraulics or closed center?

My Dad has a "666" that is open center. I think the only difference is the paint, & decals on a "686"

I think all the older tractors have open centre hydrolics i know my 686 does and all the 86 series tractors. Maybe the john deere tractors from the 70s had closed centre ,not sure on them.

the 3010 through 4960 all used cloesed center then deere switch to open center compensetor pressure controled system some of the massey fergison used cloes center 1105 and such not sure whitch one and i am sure ther are a few more who used cloes center. i don't belive any IH tractor has cloes center some of the 86 serie could have come with PFC syatems presure flow compensated but thy also were open center and was about the same systm that AC used on ther 7000 8000 series.
