Where is your rear remote valve? Is it a factory remote under the seat? Are you trying to add the backhoe to your configuration or is it already hooked up?In the photos, I took snapshots of the current hydraulics I have going on.
I have a FEL with Grapple, a rear hydraulic hookup on a lever, and now BH77.
Is the BH77 able to go through the rear valve I already have?
Looks like he got that. Easy to hook up and if he did not get it easy to make one. I think he wants to know how it hooks up to the tractor and may be contemplating the remotes on his valve.
Dan,
I understand. I think from looking at his pictures he has all of that and wants to know how to hook it up.
I do have that i think it came with the BH77, just haven't installed it yet because IDK where to put it!
It is very simple - I have attached your picture of the hydraulic outlet block and the parts diagram for the L2501 attaching kit for reference.hey y'all,
Appreciate the commentary and have a few more pictures to help clarify. The problem I'm having trying to ask the question is that I'm not sure exactly what to ask.
From what i gather I can't just use the rear facing interface I currently have, but I think I understand now that I will have to route the "Power beyond" hose to the BH77 first, then from that to the rear interface, then back into the return. Is that correct?
here's a basic diagram of my understanding of my tractor's hydraulics and where I think I need to put the BH77 in the system. It's likely wrong and that's why I'm here asking for help!

Excelllent!! That should provide all the detail the OP needs.
No I don’t think you are right. For my B2920, you hook up to the the power beyond on the loader like the instructions says, then the return from the backhoe loop feeds the remote valve, instead of feeding the remote valve directly from the loader valve.
My advice is based on hydraulic best practice. It works either way but the problem with the way your hoe is plumbed is the backhoe valve does not have a power beyond port. So you are using the tank port to supply the remotes which creates a very real potential for excessive back pressure on the tank port of the backhoe valve. Far better I think to have the backhoe at the end of the chain which eliminates that potential.
That should be in the installation instructions for the backhoe as well. Kubota finally got their act together and used a valve with power beyond on the BH70.
Dan is absolutely right, and I'll add this. If the system is not plumbed correctly, be it with using remotes or whatever, you can very easily fight yourself with destroying seals, o-rings, etc--and I've been through this. It's very frustrating. Kubota issued a bulletin that discussed exactly what Dan's talking about. Someone else can post it. Basically the backhoe valve is the last part of the hydraulic sequence and it doesn't matter how many other components are put on the PB circuit, the backhoe has to be last.
A long time back, I went to the Kubota ‘build your own’ page and while I could configure rear remotes with an L3301 and BH77, the minute I tried that combo with the L2501, options started getting ‘greyed out’.
