I'm trying to figure out which way to go with some hydraulics I'm adding and need some help. I currently have the Deere 'Power Beyond' setup on my tractor for my backhoe. That gives me hydraulic supply and return lines at the rear of my machine just above the PTO. So far, so good.

I'm currently adding a TCC which has it's control valve to the right of my seat. I also want to add a 4 n 1 bucket. My understanding is that I can run another supply and return line off the TCC control valve to a separate control and on to my 4 in 1 bucket. The problem with that, as I see it, is that I wouldn't be able to control my 4 n 1 when I install my backhoe attached because the TCC will be removed.

I thought of adding a couple of 'T' or 'Y' connectors right at my Power Beyond and just run separate lines to a controller for my 4 n 1 and leave those lines connected all the time and use the other side to switch between the TCC and backhoe. The thing that concerned my about that idea was that it seems like that I'd be a lot of hydraulic lines running from the back around to the right side of the machine.

My currrent thought is to still have the 'T' or 'Y' connector at the Power Beyond and add quick connects at my TCC control valve for all four lines going from it to my two TCC cylinders at the rear. That way I can simply disconnect my two lines to my tilt valve at the controller and connect my two lines for my 4 n 1 bucket.

If the backhoe is going to be attached I'd remove all four TCC lines going to the cylinders along with the 3PH and just use my TCC valve for my 4 n 1. If the backhoe isn't attached I could simply secure or remove just the side link hoses.

Anyhow, this has been my thought process through trying to figure this whole thing out. Does this seem to make sense and look like it will work? It seems like the simplest and cheapest way to handle this with what I have and just a couple 'T' or 'Y' fittings and some quick connects and no diverter and no second controller.

Gary,
The only place that you can use a T or a Y is on the sump line. This is a open center system and being so, it will allow the the fluid to go through the valve, line, etc that has the least resistance.

This could probably be used instead of the tee: Metro Machine Selector Valve.

You may find other brands and better prices if you shop around.

JerryG is correct. In an open center system you cannot tee or wye any high pressure line. Only the return to tank/sump line can be teed or wyed.

Also in an open center system, all valves except the last need power beyond capability since the valves are connected in series.

Hmmm... Back to the drawing board. /forums/images/graemlins/crazy.gif /forums/images/graemlins/frown.gif

At least I have another tool I can incorporate now. /forums/images/graemlins/smile.gif

You could also install a flow divider on supply line to loader, but you would lose some flow to loader. I've got two in series after my loader for extra remotes. They're adjustable and I can fine tune attachments like my backhoe that gets touchy when fed 23gpm.
