which type of rear remote valves?

[InlineDieselFan]

I could not find the answer in my search, but Kubota has "double acting valves and float detent valves" for the rear remotes.

What is the difference? And what do I want to get? below are my plans for the future, if there is anything that I may be missing or forgetting let me know.

My future plans are: when I say one set of rear remotes I mean one line coming out to the implement and one line coming back to the tractor.

Woods BH-90x backhoe with the hydraulic thumb, I am told only one set of rear remotes is needed.

hydraulic top link, only one set of rear remotes.

maybe a top and tilt, two sets of remotes?

Other than that I have my other toys/tools listed below. I do not know what else I would be buying implement wise. we very likely will be buying a post driver but it is totally self contained with it's own hydraulic pump and system.

Would I ever need or want a third set of remotes? Or do I keep my money.

thanks steve

The remote with the float just allows the cylinder to move in and out freely, just like your FEL does when you put in into the float mode.

Having at least on rear remote that floats might be nice for a top-link, but in general you do not "need" it. But having it and not using it is no big deal either... It's kind of your call...

For the BH you don't want "remotes" at all. You need "Power beyond". The flow is continous through the PBY and is what you will need. While you could run a BH via a remote, it would require locking the valve open and having a larger than normal valve.

The number of remotes needed can be given by the following formula:
(Maximum number assumed to be needed) + 1

I have 3 rear (+2 FEL) (+BPY) and am soon to be adding an additional one on the rear. Once you get used to the hydraulics, the get off,adjust,getback on method gets old fast. I would get at least one with float for the back. The BPY option will give you the ability to add further ports fairly easily, but perhaps more crudely than the factory options.

Thanks for the information but now I am getting confused.

I have heard of PBY but none of the dealers have ever said that is what I need for the backhoe when I was out backhoe shopping.

Cidertom, if I have a PBY then I can "add further ports fairly easily, but perhaps more crudely than the factory options." I think I can visualize this, two hoses that come to the rear of the tractor for the backhoe, then then a valve control unit and ports to hook up other hydraulic features, like top link top and tilt?

Hydrauilcs are just too confusing, just give me two options have them or not. Then make everything work one way if you do have them. Choices can be bad when there are too many.

Thank you, steve

Steve:
Problem is: Since your needs and mine are different, then my opinion may not do you much good. It would be like me telling you what size hose to pull on a fire, without seeing the fire or the building. (and don't get me started on nozzles )

Why no one has mentioned PBY for your BH needs is a good question. The only ones that I know of that don't use PBY are those that have a self contained PTO pump and tank assembly.

My recomendation is PBY and one remote. Again, you can add valves in series with the PBY in the future for additional remotes if you find you need them.

A lot times, a dealer will call the PBY, a backhoe kit or backhoe hydraulic kit. This simplifies it because he doesn't have to explain what he means.

Consider that you cannot use the backhoe at the same time you use the turn and tilt. The backhoe must be removed to use rear implements at all. So the same hydraulic output from the tractor can be used for both, in different times/configurations.

My B7800 has a set of rear remotes - two hoses that come from the front loader valve (which obtains IT'S two hoses from the side of the tractor transmission) - one out hose and one return hose. The backhoe has a complex six spool valve that performs the six operations involved in the use of a hoe. The dipper (which also curls) and boom cylinders, the two side stabilizers, and the two cylinder swing from side to side motion of the hoe.

I aim to add a hydraulic thumb to the hoe by using a single spool valve connected between the backhoe valve and the tractor. It will need to continue the flow of oil that existed before it's arrival so it will have both backhoe side and tractor side connections in addition to it's two working ports ( a third set, one in and one out) I'll simply be adding another function for that river of oil as it passes through all of the six, now seven, function valves. The new valve will mount in the control tower of the backhoe and leave the tractor when the backhoe is removed.

When the backhoe is off it's two hoses are either connected together in order to maintain the circuit of oil from tractor to sump through the front loader valve, ...... OR I can add a new valve, a two spooler this time, inserted into that circuit at the disconnect and route the work ports of that new valve to a top and a turn cylinder for the favored T&T. This valve must be able to continue the flow that existed before it's arrival.

The tractor pumps oil out and receives oil back whether valves, cylinders, implements, or anything at all is connected in the circuit or not. It probably doesn't care one way or another.

Is any of this clear? The valves you add must be able to pass the oil through them to the next work valve or back to the tractor. They will be waypoints for the oil flow, tapping it's pressure/energy to perform work along the way.


Valves are supposed to be marked for the function of each port but I'm finding assorted markings on mine that so far are as clear as Egyptian heiroglyphics would be to a newborn baby.

such is the extent of my understanding of this hydraulic embroglio at this time.

I could not find the answer in my search, but Kubota has "double acting valves and float detent valves" for the rear remotes.

Some tractors have remote hyd valves that have detents. This allows
you to use one of the remote circuits for either a double-acting cylinder
or for a continuous hydraulic demand, like a hyd motor or backhoe. The
detented valve eliminates the need to plumb the backhoe in series with
(upstream or downsteam) of the remote valves.

If Kubota offers OEM detented valves, then that is how they probably
expect you to connect your bh.

I have plumbed my hoes off the BYD port of the FEL valve, off the main
hyd block on the tractor, and off an OEM remote valve with detents. The
last is how my newer Kioti does it.
