Where does the small coolant line below the lower rad hose lead to and what is its purpose ?
Thanks

Could that be going to the oil cooler mounted in front of the rad (#16)?

Just to be clear.. do you mean a B6200? I am thinking this is a typo because B6100s dont have HST and don't have this hose.
At least if its a b6200 someone could dig through the proper diagrams and possibly determine its function.
In general if it goes from the lower radiator hose area of the radiator to something higher up, it is probably trying to facilitate convection flow in the area of the engine that it hooks to. So, the little hose would let cooler liquid in, and the hotter liquid would flow 'out' of that area, internally to the engine somewhere. That's just an educated guess based on what you said and not having seen a pic/diagram.

Sorry guys it is a B6200 HST-D
There are two pipes on bottom rad tank one is lower rad hose the other is smaller pipe UNDER the rad hose and leads up under fuel pump into engine block.

I do not know if this helps any but my B6200 gear driven has the same hose. Bottom of radiator to lower portion of the block directly below bleeder.
Too lazy and apathetic to take off the covers and get down in the dirt to take a picture and plow frame blocks the view for a camera to slide under.

Thanks Guys, I called the locall Kubota dealer and they call it a drain tube . I guess it is for complete draining of the block after draining the rad ???

Why would a drain need to be connected to the radiator when a simple drain plug would do.
I'd take that explanation with a grain of salt.

Well that's a nice touch, i guess. All blocks have 'block drains' which can be used to drain the block if, for example, you had tap water in it and wanted to try and get a 'pure mixture' of distilled+coolant, or pre-mixed coolant etc in there.
Most engines have the lower radiator hose hooked up to them somewhere about halfway vertically up their water passages, so the radiator drain itself will only ever drain the block about halfway down and the rest will just sit in there. If you ran a hose from the 'block drain' hole to the bottom of the radiator, the radiator drain plug would actually drain the entire block too. That's cool.
