I agree. I was speaking of my new 5090. But my 2002 model 5310 was exactly the same. Any one of the three SCVs would operate my single acting cylinders. My FM has 3 of them so all 3 remotes have to work.
/ 4440 - operating single acting cylinder from remote?
Your 5310 & 5090 both have open-center hyd's which operate a lot different than JD tractors with closed-center hyd's such as the 4440 which this thread was originated about.
