Running a brush cutter off my thumb circuit.Cutter only requires about 2/3 the flow available and I have the cutter rigged up with a flow control valve that diverts excess flow back to tank. (Both the return flow and the excess flow go into the 1 inch dia return line that runs to end of stick for rock hammer return flow )
This all works ok but other functions are very weak as long as cutter is activated .Cutter stays at flow controlled rpm unless I raise boom when I can hear it slow down,which isn't a problem.
Seems to me it'd all work better if I wasn't dumping all that unneeded flow back into tank.
I'm thinking if I had a pilot pressure regulator? in the thumb pilot circuit I could dial back the thumb pilot pressure and hence thumb circuit flow to where I want it. Does this sound right? Better ideas?
