Does somebody know this Hydraulic Control

[cabu]

Hello,

I have bought a Kubota B1-15.
On the label it is named B1502DT.
And in the Gallery I have seen that a B6200 looks like my B1-15.

The seller promised me to give my a manual, but ... :-(

So, my question is, does somebody know that control of the hydraulik?

And another question is, how to operate that valve in the following picture.
(I believe it is for the flow of oil of the hydraulic connctors at the back for additional equipment.)

Is there somewhere a switch or do I have to connect a cable?

Thanx for Help!

Cabu, It's real doubtful that Kubota installed aux hydraulics on that Aste B1-15.

The device you have "arrowed" is an electrically (12V) operated directional hydraulic gate valve, and it is part of your Kubota's Monroe Matic "Electric/Hydraulic" sidelink system attached to the RH side of your tractors 3 point hitch.

It will not function "fully" unless the Swing Sensors that are part of the rototiller are not connected to the plug in port located at the rear of the seating area of your B1-15.

Right now, you probably have limited operation of just the hydraulic side link, up and down manually. However, the Monroe Matic system was designed to adjust the angle of depth of the tiller hydraulically via electronic feedback from the position sensors located inside the "Swing Sensor" boxes.

As well, Monroe matic equipped Kubota tractors have a sensor on the position control of the 3 point hitch, that when the hitch is raised, the hitch will automatically level and adjust itself to it's normal operating balance, regardless of the input being rec'd from the swing sensors.

You're never going to get that manual. It does not exist! You do not want to tap into those small hydraulic lines feeding that hydraulic side link to power up anything auxilliary. There is minimal flow to that cylinder, not enough to operate anything!

Thanx Vic,

it's always nice to get a quick and good answer !! :)

Regarding the connectors for the external hydraulic equipment here is a picture to give you an idea what I mean:

There is a pipe connectet at the right side to the ventblock und it was hanging down in the dirt when I bought the traktor. There was no diffence in the sound of the engine after I connected it to the plug, at the left, just next to it. So I belive that there was no pressure in the pipe and after connection there is no flow of oil.
That's why I was asking how to switch this on.

And I have another question regarding that Monreo Control. In that position of the lower left knob, it is possible to adjust the hitch hight with the handle, on the left with the scale.
After some minutes of use the control sometimes does not move anymore or it is swinging up and down, and shake the traktor. Or only goes up or do other strange things.
Do You have any experience what normaly is broken or used up, if this behavior comes up?

Thanx for Help !

Does you tractor have a hydralic side link attached to the RH side of the 3 point hitch?

Looking at that hose, I can tell that part of your Monroe Matic System is missing.

Normally there are two spring wound hoses, not just one. Both of the hydraulic lines then go to the hydraulic side ling which is a double acting hydraulic ram, hence two lines.

It appears as though someone deleted a line and added a hydraulic quick connect, then, and I can't see the whole picture, looped the other hose to make a loop.

These systems don't usuall fail, they work real well. If yours is not working properly you may have a wiring issue especially at the area where all the wires connect, the upper back corner of the RH fender, just bejhind the seat.

Thanx Vic,

what I understood is, that there should be two of these hoses and they should be connected to a vent block.

Ok, so somebody took the ventblock in Japan...

But my question is still how to get the oilflow started? Is there a electric vent I have to power (That's why I thought it is the vent in the 2. Picture). Or does the traktor has a manual vent somewhere like a B7001 has? Ah, yes: I did the loop, because it was hanging down in the dirt. But with or without the loop there is no difference in the sound of the idle engine, that means that the hydraulic pump is not forced to power a high pressure. If I raise the hitch, you can hear the workload of the idle engine after it reached the top position. So, why is there no workload when I disconnect the hose. So there must be no pressure in the hose.
Where is the point to switch it on?? :(

And maybe You can help me with my other question regarding that Monreo Control. In that position of the lower left knob, it is possible to adjust the hitch hight with the handle, on the left with the scale.
After some minutes of use the control sometimes does not move anymore or it is swinging up and down, and shake the traktor. Or only goes up or do other strange things.

Carl,

Does your tractor have a hydraulic side link on RH side the 3 point hitch when viewed from the rear?

Hello Vic,

I can't tell you at the moment, because I am on a business trip in China. When I am back home I will take a look/picture.

Thanx for your help !!

Hallo Vic,

so finally I was at home to make some pictures.

And also of a label at the back.

The Question is still, can I switch on/off the oilflow? Because it seams that there is no pressure in the hose.

Yes. Pushing in the button on the solenoid (the first picture) will activate the valve and send fluid down that hydraulic line. You still did not send a picture of the 3 point hitch, I need to see if you have a Monroematic hydraulic side link on the 3 point.

[cabu]

Thanx for the answer, Vic.

I am back on a business trip in China and not at home, so I can't make some pictures.
But I bought the traktor with a cheap 3p hitch and the tiller has also no switches/cables. And I have found some free connectors of the Monroematic under the seat. Next time I hook up the tiller I will just use the not-so-sensetive selection of the control. Maybe that helps to stop that shaking.

Again, Thanx for your help. :)

Hi Carl,
Long time no see. I am quite impressed when I saw what you did with your B1-15.

Did you finally find out the secrets of that solenoid valve? I actually have exactly the same setup on my B1-14 and wonder whether I could use it together with the hydraulic hose with quick connector to actuate a hydraulic top link for my 3pt hitch. Did you identify the type of the valve? I guess that it must be a 4/3 way solenoid valve with 2 electrical actuators (see attachment) as I have 2 white and 2 black cable going inside.

Do you know whether the white or the black cable is the + pole?

Regards
Tom

Hello,

I disabled it and disconnect the cables.
I have already added an extra hydraulic block!!

Hope your B1-14 is fine
