Been searching for information to help with the Load Rangers hydraulics, plus the add on electric or hydraulic lift posts, and found this diagram on connecting a hydraulic system with multiple valves and cylinders. I wasnt sure how power beyond systems were connected and this diagram does a good job showing that also. This is with Prince SV stack valves. Might be more than most tractors need but I thought the information might be helpfull.
