Upon receipt of my 3316HST, I've been going through and rerouting Hyd hoses, retorquing all hardware. I found one hose that was installed with the loader located in such a manner that the foot pedal arms were rubbing on the hose. The three additional hoses for the BH were not run to my satisfaction either. Also took the opportunity to color code the hoses with electrical tape: Green = tank, Red = pressure, Yellow = power beyond.
My manuals that came with the 3720B unit isn't very clear so I'm asking the questions here. This is a fairly generic question with regards to adding a BH and the flow of the hyd fluid.
What I'm trying to figure out is when the BH is ready to be separated from the tractor, I should be re-connecting the P or T or PB hoses (on the tractor) but not sure which so the tractor fluid system stays closed.
On any other BH unit separation from the tractor, you have to reinstall a hose so that the tractor fluid keeps flowing in a closed system. This hose is behind the driver seat. That is what I'm trying to figure out on my 3720B since it's different from other BH units. This unit has a large subframe that stays with the BH so all of your hose connections are near the engine.
This pic shows the Pressure (red) and Tank (green) hoses and associated quick disconnect fittings.

So, when I disconnect all three hoses for the BH separation, am I suppose to close the system back up by connecting the P to T ?
I hope I made some sense
