Kubota model 1200 loader

[Ollie’sL-185DT]

I own a Kubota L-185DT with a Model 1200 bucket loader on it that my uncle left to me, seeing what hydraulic valve body I can replace my current original one with, pretty sure it’s original and every time I fix it, it breaks or starts leaking again, just want to replace it and keep it stored for parts,

thanks in advance

Any open center valve with a power beyond adapter will work.
Ideally you want one with about a 5gpm capacity, but you'll most likely will only find higher capacity valves.

North Idaho wolfman,

Thanks for the info I down loaded a owners manual for the model 1200 and there’s nothing in it about hydraulic valve body or anything, thought that was kind of weird, is it the high the gpm’s the faster the system will work?

Normally yes the higher the GPM's, the faster the system will work.
But in your case you are capped by the speed of your pump somewhere in the 3 to 5gpm rate.
And using a Spool valve with a higher GPM capacity will make it where you will lose fine function.
It's not a killer but it's something to be mindful of.

First question - is the loader running off the tractor hydraulics or does it have its own pump? I am goung to assume its tractor hydraulics.

There are plenty of inexpensive choices fir control valves. I think you will want a joystick valve with a fourth position float on the boom spool. Thats a major step up from the original. Here is a popular loader valve from one of our OTT vendors. It has SAE ports and the power beyond conversion sleeve has to be purchased separately.

That P40 design is manufactured and sold by a lot of different vendors and you can find them for half or less of the one I linked. Be careful - they often have BSPP ports, no float position, and no power beyond sleeve, That can become a costly and aggravating added expense.
