All of the valves can act like simple DA valves, but the way I have the M set up I don't use the SCD valve the way it can be used, i.e. I don't lock it out and have it kick back to neutral when the flow dead heads. Typically I use it like a DA valve. The FD valves are mostly used like DA valves too, but for some tasks I do use float.
Your question reminded me that when I run the folding cutter this summer I'll be disconnecting the couplers that currently control the top link so that I can connect the hose from the cutter to float the wings. The hose for height control will connect to the 4X multiplier although it could connect to the remotes controlling the side link. I'll have to see which approach I prefer.
I'll probably follow @MtnViewRanch's suggestion to raise the 3-point all the way up, shorten both the top and side link cylinders as much as possible, disconnect the hoses and secure them out of the way. The folding cutter pulls off the drawbar so the 3-point isn't needed.
