BX2015a "float function"?

[twomany]

I purchased a BX2015a two spool unit in a private sale.

The seller was a bit surprised when the float function was investigated during the inspection process. He didn't know it was there even though he had used the unit on his own snow blower fitted BX.
After mounting the unit on my B7200, (it fits, and looks "factory"!). I can feel that both spools have a float function, but that the detent for the "left/ right " or bucket curl and dump does not retain the float position. The fore/aft. boom lift and drop works "normally", with the float detent holding position until pulled back.

I'm not fitting a loader, but rather putting power to lift and rotate the chute of a front end snow blower. So a retained detent does not matter for chute control.

But.....

Is the non-retained detent for the float function on one of the two spools "normal"? Or is there something amiss in the float function detent assembly?

Also, of the three ports not associated with control function, one marked BY, one marked P, and one unmarked. Can I assume the unmarked port is return to tank.

I'll likely blow air through the control valve to double check, but thought to ask along with the original post question.

TIA

I haven't searched for your valve functions, but I expect it may be a regen position for the bucket.

good point!

I can't imagine regen being handy for chute rotation but... if a situation needed the snow stream diverted in a hurry.... well, there it is;-)

Regen, depending on, if, and which position it is, is not suited, do a search for blower and regen or similar, has been discussed before.

thanks for the heads up and reference.

I will need to better know the DCV functions. I have not had luck getting valid info off the net.

I suppose I could put this valve to good use on the loader fitted tractor that presently does not have the regen feature on the DCV for the bucket. Oh-So- Slow on the dump, unless the revs are up. ;-)

From this reference (if the Kubota valve follows ) Everything should be good to go to run a chute rotation via a hydraulic motor. First position to the right is "normal" mode, all the way over, past the "bump feel" is the regen function. No need to go there for chute rotation. ;-) Thanks for the comments!

I could be wrong, but have a feeling some of the later series Kubotas have 2 dump positions, first one is fast and 2nd is slow. Whether yours is, no idea. If this is the case with your valve, you'll just have to go through to the second position. We'll have to wait and find out hey? At least it's not a "regen only" valve.
