I have what appears to be some kind of mid remote that is operated via a handle. It is feed from the PB off the loader control valve. Can I feed a 3rd function? Any one seen anything like this? Would I be better off feeding a hydrualic control valve directly off the subject PB.
Mid remote for function

It is not at the rear it is on the side. It also has a handle to operate and does so but you have to reach under the platform to actuate it
Post a couple pictures of the valve.
To answer your original question, if the valve is a double acting directional control valve it could be used for a third function. But based on your description it may not be a directiobal control valve. My suspicion is it is a diverter for the backhoe. Even if it is a directional valve it would be terribly inconvenient as a third function. .Adding an electric 3rd function control vslve between the loader PB and the mystery valve is a much better way to go.

Dan, it appears the loader valve on the L45 and L47 has 3 spools. The stack is mounted under the floor and is cable actuated. Two cables go to the joystick and the third goes into the pedestal but it's not obvious to me what actuates it. Same with the hoses, not obvious where the third set goes. Maybe the machines are prepared for third function?
This may be applicable to the guy installing a grapple, but I think he's further along with his install.
Thanks, I dont have any documentation for that machine.
I was just getting ready to look at the loader parts diagram. The L45 parts diagram has me baffled. It describes a optional third remote but I cant find the first two anywhere. The handle for the third remote seems to be located on the right side operator console with the position control lever. The 3pt hitch linkage is listed as an option.
Maybe they mean third function, not remote? I'm just going by the parts diagrams also.
The L35 and, maybe L39 and L45, came with the full 3pt setup. The later models have the hydraulics and rock shaft arms only. An option kit is available with everything else.

Hmmm. The online l45 parts definitly ,(??) has the 3pt linkage in the options section. In any event Eric probably wants an electric third function. I currently have a manual valve on mine. It wirks OK but less than optimal. It was supposed to be a "quick and dirty" while I engineered my own electric version but fibrotic lungs got in the way of the quick part. Its back on my bucket list for this summer.

As you know, I added a third valve to my loader control stack. It made a clean installation, fewer hoses, and I'll probably stick with it. But I need to close the grapple while rolling it back and lifting it. If I installed an electric valve before the loader, I think these operations could be done simultaneously. As it is, I can do tilt and lift but not close. And I haven't mastered two sticks with one hand, either.
J have spent a fair amount of time studying Kubota loader circuits and this confuses me
Kubota likes to use a series spool for the boom which puts the boom in lockstep with the bucket. I dont know if thats true of your sectionsl vakve.
Either way your 3rd function valve should be in parallel with the bucket so they dont block each other but the least loaded function will get priority and potentially stall the other.
An electric third function is a little different. In this application they are using tank for high pressure carry over and are effectively serial.
If placed after the loader valve they are in serial with the boom and work in lock step with it. However the bucket spool is between the two and if shifted will divert the neutral to tank and block the third function.
If the third function is placed ahead of the loader valve all spools are in series and will operate in lock step. If any individusl function stallls it will stall the other two.
So pick your poison. I tend to lean toward putting the 3rd function ahead of the loader.

Well Professor, you sent me back to the books. After brunch at WH I broke out the manual. I see what you're saying and agree. But in real life, I haven't been able to do it, not yet.
With the backhoe, on the other hand, if I want to pull the spoils back into a stump hole, I reach the stick out, pull both sticks full aft and she booms up as the stick comes in, bucket practically level with no modulation.
I guess the difference is the difference in loads on the two functions. I've got plenty of practice time coming up.

Its just hard to meter parallel sections because of the constantly changing indeoendent loads. The first thing I noticed when I got the LA725 was how smooth the boom and bucket control was. Thats when I hit the books

Ya know being "under" the machine as I believe the OP mentioned, I wonder if someone made a pattern selector for the backhoe? Seems like overkill but maybe something homemade so they could have multiple operators use the backhoe? But seeing as they mentioned off the "power beyond" thats whats confusing.
Do you have a WSM for that? Could you post a screenshot of the hydraulic diagram? I'd like to see how that works.
My L35 has anti-dumping. It's a linkage setup that physically pushes the dump valve if the rollback is excessive as the boom raises. Not really useful for keeping pallet forks level, but ideal for my use.
