Help needed with tractor remote operation.

[adkalex]

Hello,
I bought a new (used) tractor and it has remotes at the front and rear (see pics).

I have done some research on this site and others and I still do not have a tight handle on how my specific remotes work.

My tractor is a 2012 Kubota M5140. I thought I was fairly intelligent...I was wrong. I understand what the remotes do in general, but I am confused on the different types (detent?), their function, and how to operate them.

There is a picture of the loader controls and the front remotes. I believe the small white button activates the front remotes and then the 2 black buttons control the flow. I am not exactly sure how. Can anyone explain. I am hoping to hook up a plow and control the direction with these.

Then at the rear there are another set that I believe are controlled with the lever pictured, but I do not know how.

There is also a single hydraulic hose by itself that I do not know what it is for or how it works.

Finally there are connections for the backhoe that were hooked up upon purchase so I understand how the connect and operate. From reading the manual I read that these connections need to be hooked together when not hooked to backhoe (no picture).

I would greatly appreciate any help.

Welcome to TBN.

Seems like you have the general idea.
The only thing you say that I question is the white button. I am guessing the white button is not used to activate the front remotes as you say. The two buttons on the loader control should control the front remotes by them selves. If you had an impliment with a dual acting cylinder like a grapple or angle plow connected, one button would open the grapple or angle the plow one way and the other would close the grapple or angle the plow the other way.
If I am wrong on that hopefully someone will jump in and correct me.
The lever near your 3ph lever is the control for the set of rear remotes. It will control a dual acting cylinder (one with two hoses) or a single acting cylinder (only one hose) Push one way to extend the cylinder. Push the other to retract the cylinder. If you want it to go the other way just swap the two hoses.
The single hose may be for a single acting cylinder. I have one on my sicklebar mower. It only takes one hose. I push the lever one way and the cylinder extends hydraulicly, raising the mower bar. Push the lever the other way releases the pressure and the cylinder drops from the force of gravity not hydraulic pressure. A dump trailer can also work this way so it would also be good for that. The white button could have something to do with that. It might be that holding the white button switches the rear remote lever to control the single remote on the rear.

Again what I have said is a pure guess based on common practice. Yours could be set up different.

It might be you have to experiment a little and follow some hoses around so you see where they go. It is good to learn about your tractor anyway. Can you call the previous owner ??

I'm fairly certain that the white button at the bottom of the loader joystick is to enable/disable the use of the 3rd function on the loader and for controlling the 3rd function (normal operation for a grapple, plow, or whatever), you use the two buttons built into the handle of the loader joystick. Hopefully that make sense.

And yes, the other lever is for the operation of the 3PH remote. If you have float on the 3PH remote valve when you push it forward hard, it will click into a float mode (same as you do with the FEL) - otherwise, if it doesn't do this then it's double acting.

Thanks lots of good info. I will trace out the lines today. Members on this site are great, always very helpful. I will update my findings later today.:thumbsup:

From some more research it looks like the white button does activate the third function remote up front. The black buttons then control the direction of the flow.

The side lever controls the rear set. You can push or pull the lever and if you push or pull harder the lever locks in.

I traced out the single line and it goes back into the tractor near where one of the backhoe lines goes (which is the same area as the front remotes and the loader valves).
I am still not sure how it functions. I will keep researching. If anyone has an idea let me know. Thanks for the answers.

You have one set of rear remotes and a front 3rd function. To tell if the rear set is a detent or d\not is to pull back or push forward the control and see if it goes back to center.

 

[adkalex]

The lever does go back to center unless you push/pull until it locks in. I guess this means it is not a detent and when locked in it is in the float position?

The single line in the rear comes off of a steel line that goes into the valve that the front loader lines attach to. I will take pics and post them.

Exactly. You have a float function on that remote.

From what I see they appear to be the factory Kubota options. Don't worry about how it is plumbed. Go buy something to use them and enjoy!

I suggest a grapple for the front and a hydraulic top link for the rear.

I think I need to apologize for leading you astray. It did not register with me that there was a backhoe connection on your tractor. I believe you will find that the single line is the backhoe hydraulic return to tank connection and it is teed into the return to tank line from your loader valve. The backhoe lines that you have connected together with a short loop are the power beyond lines.

Sorry I got carried away and caused confusion.

No confusion. Your answer was very helpful.

I am still unsure of the single hose. It does go to a T up near the loader valves into the tractor(first pic). Then continues to another T (second pic). The metal line that comes out of the second T goes into the front of the loader valves (pic 3).

The lines I connected together from the backhoe- One is a metal line that connects just under the rear remotes (pic 4) and the other hose goes up to the connection where the loader connections are. It does not T into anything in has its own port (pic 5 bottom most port).

I am not sure what power beyond lines are. Nothing was hooked to the single line when the backhoe was attached.
