Dual Acting Cylinders vs Single Acting on Implements

[XxLT250RxX]

On my previous tractor there was a screw on the valve that controls the rear remotes. Turn the screw in to control dual acting cylinders on an implement. Turn it out to control single acting cylinders. How does this work on my Mahindra 2565? I don’t see a screw to switch it to single acting cylinders.
