Thanks all for bearing with me for what probably seemed like a bunch of stupid questions for the last week or two while garnering information regarding adding remotes to run my snowblower hydraulics. I must've learned something though, because I finally got a chance to trace out the lines on my tractor, and I now understand everything. Crazily enough - almost every piece of info/advice had both good and bad information in it. It was good to get it all though, even though I was really confused for a while, because once I traced out my system, I understood everything.
As it turns out, my originally plan for adding remotes using the backhoe PB connectors IS no good and won't work. Backhoe and 3pt ARE, in fact, mutually exclusive. The PB from the loader is used for the 3pt **OR** the backhoe, but I have to move hoses via a QC to choose one or the other (assuming the 'IN' port on a Kubota hydraulic extender block is the input to the 3pt hitch). I think this type of hookup is pretty common. However, the BH is NOT magic and able to run with PB on both ends like the tractor shop guy said - one connector is the PB from the loader, and the other simply a tank return, so it is like any other remote valve setup, but has to be the last in line (no PB output for a next stage). So, I could hook the remotes onto the BH connectors like I planned and they would work, but if I did, the 3pt wouldn't work, which defeats the whole purpose. I do need to add a third line like the shop guys said, but NOT for a tank return like they were saying, but in fact need to add a PB line from the remotes that goes back to drive the 3pt input.
I figured out an easy way to hook up what I need using the existing plumbing - the existing loader to BH PB run becomes permanent, which powers the remotes, and I only need to add a single hose for the remote PB/3pt input connection - which I can run to the existing 3pt QCed hose, so adding the additional line should be reasonably painless, and I can use the existing ports to power/return the new remote circuits.
The biggest problem I see now is finding a mounting location for the connectors - my ROPS is completely in the way. It runs right beside the 3pt arms, completely covering the space between the 3pt arms and inner fender. The area above the hitch is open, but routing hoses will be tight there, and if used will further block access to the transmission fill port, which is tight as it is. Even the existing BH connectors have to moved - hoses can't be connected to them if the 3pt hitch is used due to interference. Finding a spot to mount even those 2 connectors (plus the new one) that allows required hose routing AND 3pt clearance is going to be tough. 7 connectors would be out of the question. Because of this, I'm really liking my plan of mounting the valve set onto and arm connected to the blower, with 3 connections (IN/OUT/PB) to the tractor. This makes for easy conversion too - unplug the 3 blower connections, and I'm all set up to plug in the backhoe. Short the new 3pt PB port to the existing BH PB port, and I'm set up for 3pt operation (w/o remotes). That's all I need for now.
