Kubota 2610
Long post, but bear with me, I want to add rear remotes to my Kubota LX2610. Yes, I have done some research and think I have the right solution, but want to run it by folks before I do. Important to note that I already have both a backhoe and a 3rd function valve installed. The backhoe is e BH77, so there are only two lines (some backhoes have three lines), Power and Tank

The LX2610 comes with a power beyond port on the loader valve. Without the third function or backhoe, this is piped right back in to Tank as you would expect. With the 3rd function only, this pipe would be removed and the new hook up would go PB -> 3rd Function -> Tank. With the Backhoe only the pipe would be removed and it would go PB -> Backhoe -> Tank. With that back hoe not attached, you connect the two lines together (PB & Tank) and complete the circuit.

Since I have both, it goes PB -> 3rd Function -> Backhoe -> Tank. Attache the two backhoe hoses when not in use to complete the circuit. Now I want to add a rear remote.

The way I see it there are three options (spoiler alert - I think I want to go option 3).

Option 1:

From what I have researched, Kubota sells a rear remote kit with manual levers that pop into a tray in the tractor. So how do these remotes get power? There is what appears to be another PB port, that is essentially a diamond plate that covers two lines, and normaly ports power to tank, but you remove it, and attach stackable valves to it. You can do up to two valves and one of those can be a float valve. These are manual valves and the levers integrate into the fender tray.

Pros: Kubota Kit, Plugs into an existing port, levers that integrate into Kubota design, option for a float valve, whole unit is out of the way, tucked under the fender,.

Cons: Max is two cylinders you can control (can’t add more - not enough room). Once you get the valves and levers it is about $1,800 - $2,000.

Option 2:

Instead of using the Kubota Kit, I could get a kit from Summit (or someone else, doesn’t matter) but I would need power. I mentioned the additional power source that is covered by a diamond shaped plate in option 1. Kubota also sells a conversion plate, that you replace the cover plate with. It has two ports ( a P and a T) that could be used to power the summit (or other) unit.

Pros: The summit unit (for two rear remotes) is $850 and the Kubota conversion plate is about $250. For another $150 I can get three instead of two rear remotes.

Cons: Summit has no option for a float directional control valve. The valves are attached to the ROPs, not hidden beneath the fender. The summit system is an electrical switch box that has to be attached somewhere, not levers that are integrated into the LX fender. Eletrical valves don't hold as well from what I have read.


Option 3:

Skip using the extra power port on the kubota. The outlet (tank line ) of the 3rd function would go to the P port of the rear remote. The Outlet (tank line ) of the rear remote would go to the Backhoe. The current Backhoe Tank line would stay as is. So the routing is PB -> 3rd Function -> Rear Remote -> Backhoe -> Tank

Pros: No conversation kit necessary, but would have to run some new lines. Cheapest, and maybe easiest option.

Cons: Same as option 2.

——————————

Summary:

The Way I look at it is that option 3 makes the most sense. While I can’t get a float valve (at least with summit) I am not sure that is that important. I also have the option to go 3 or 4 valves (for more money) if I want. Option 2 is only slightly more expensive than option 3 but has no real advantages.

My Questions
- Is Option 3 viable? (Take return/tank line from 3rd function to P port of rear remotes, return/T line of rear remotes goes to P port for backhoe)?
- I am looking at top and tilt, so thinking I just need two cylinders, does anyone end up really needing three? I don’t have a hydraulic blade but maybe that is where it would be nice to have three. Any other attachments you need three for?
- How important is a float valve vs being able to get three or more valves? While it might be nice I just do’t see being able float the top or side link that important. At least important enoiugh to spend an extra $1000. I could be wrong here.

Option 3 looks correct except that it's the power beyond port of the rear remotes that goes into backhoe loop. Unless your rear remotes valve block does not have PB or the option to install it, and it's tank port is rated for full system pressure. The one I have is one of those. But they're not that common.

You'll have to dig into the docs for the valve to find out what its tank port is rated for. If it's only 500 or 750 psi instead of 2500 or 3000, you can't use it to feed pressure to downstream valves.

Thanks, that is helpful. The block I am looking to use is the Summit block (link below), it does have two work ports (P & T) that are normally plugged - I am guessing in that case I would run the P work port to the backhoe and return it to the T work port. It was my understanding when I did this though that there was normally a plug or something you need to put in a different spot to close off the internal connection between the P&T ?

If you also have a Power Beyond port, the T port on the valve gets plumbed into the tank. You can tee it into the tank line from the loader valves.

Often there is a plug to enable/disable the PB port. ("P" is usually the designator for the input pressure port).

Lots of people say that there is no need for the float feature on rear remotes. You will find that most of those people have either electric valves (no float feature available) or have cylinders with check valves, because of the electric valves or just poor quality valves in general.
You will find that just about everyone who has a valve-s with the float feature and actually understands where & when to make use of the feature would not be without that feature.

Realistically it depends on the different tasks that you will be doing or plan on doing in the future.

Electric valves simply are not ideal for controlling top & tilt cylinders.
Lots of people use them, I think mainly for the cost and ease of installation. So they do work, but with no feathering capabilities and no float feature option, not the ideal setup IMO.

Good luck with your research and final decision. ;)

Thanks, based on a lot of the discussion I think I am going with Manual valves and getting float. Rather get it now and not use it, than not get it and wish I did.

Exactly, I highly recommend Bucher Valves.
