No clue offhand how you'd do it without a valve up there. Unless you had a dedicated SSQA line or plumbed in something in the operator station. All the implementations will require a 3rd function, either a true 3rd function or diverter would work.How does it work? I can't quite figger it out either. FEL vs Implement vs Quick Attach.
Ptsg beat me to it but the valves are tucked up behind the cross tube. Out of the way. One for each line.
It is quite fast but not too bad at idle. I may get a restrictor just to slow it down a tad.
