Hi Everyone.
I want to install hydraulic splitter on my Kubota. And I'm wondering if could use one of the existing holes as a return:

Any ideas?

Also I would be grateful for sharing your own experience in that matter 🙂

A lot more of an explanation on what your trying to accomplish will get you better answers.

That tractor has a crawler (slow speed) setup doesn't it?

For the tank return, but you'll note if that is a vented plug you will need to tee and add the vent back in.

I know nothing about that model but I doubt thats going to work. Do you have a loader on the tractor?

Dan
No I don't.

It has 3 gears H, M and L. As far as I know it is almoust the same as L175/L185 but has hydraulic drive. So it has crawler setup. I will check it's vented, but I don't think so.

Explanation what I want to accomplish:

I want to add hydraulic splitter and set of connectors in the back. I want to cut the oresseure line (shown on the img) and connect to the P socket on the splitter, the power beyond (N) will be connected back to the original pressure line to run the 3point hitch.The T socket should be connected to the oil tank, I don't want to cut more things that is necessary. That's why I posted my question.

I can post more pictures of my kubota if needed.

I assume your splitter has its own control valve. If so all you need is a hose loop in the tractor side pressure (neutral) circuit. Hopefully you can do that without cutting anything.

As I asked earlier - do you have a loader on the tractor? Or any other hydraulic options?

No, I don't have loader. Only stardard hydraulic setup.
That's basically my question: Can I close the loop using using one of above holes. I will try with the one suggested by Wiolfman.

STOP!!

You cant use that filler to make your pressure loop. Dont do anything rash. Show me some more of the pump pressure connections and the area under the left side of the seat.

I want to use it for hydraulic links or hydraulic tilt shift mowler;
I will send more pictures after work.
Thanks

Whst you want is commonly called rear remote outlets. Now that we have that clear lets get to adding the plumbing for a remote valve.

On the L185 you would do that here and it looks like your tractor is similar. You replace the cover I circled with the two port outlet block pictured below. No cutting - just bolt it on and plumb it up. with a coupke hoses. Tank return from your remote valve goes to the oil filler port.

Yeah, I did want to do so, but there is no space for that. The part with this cover is misisng and there is no place to put it because of gears leaver.
1787836865809.png 20260827_144034(1).jpg



That's why I have to connect it like that:

1. Cut the oressure line
2. Connect to the hydraulic directional control valve (I called it splitter - that's why you missunderstood me in the begining. [Green line]
3. Control valve has power beyond. I will connect it to the remaing pressure line to power the three-point hitch. [Green line]
4. Tank return connect to oil filler. I think there are two (same orange-ish color). One visible in my previous post. I used it to fill fluid. Second one, marked by North Idaho Wolfman. Do you think I can use the second one? [Purple line]

Thank you Dan for your help. I really apprrciate it.

Make sure you get the pressure beyond plug/adapter for that valve.

For educational purposes you can see post #1 in this thread for how the block diverts fluid as you need it.

On my L185F the block was installed in the line as it crossed the transmission. Here is a picture of how it connects to the rear remote valve. Red is pressure from pump, blue is power beyond from the rear remote valve and green is tank return.

Here is a L245 block in a similar location as your picture show

I already have adapter.

Thanks for that. Very helpful. The green tank return is very interesting. I think this may be similar screw to one I have on my kubota. I've checked it today, it is oil dipstick. It's not mentioned in the parts manual - that confused me.

I just checked, and I found similarities between yours and mines.

Regarding the block. I don't have enough room for that. There is a oil filter right in front of this. But I want to do basically the same thing but without such block.

YES you can do exactly like you stated.

1787846614534.png

On your model this is where the adapter would go, But that adapter is Really hard to find.
I have a similar adapter on my tractor (pic below)
