Ever since I cleaned the strainer and drained the hydro then put SUDT in it I haven't had an issue.

my new b3200 does something simular sort of. i have been bush hogging with it and i have been locking the knob under the seat to keep the 1/4" valve 3ph from leaking down while bush hogging.=(3ph bush hog) anyways, i always turn the knob to open to raise the bush hog when done and it will squeal like you said yours does. i have noticed that if i let the pto spin down and don't raise it immediately when i am done, it doesn't make the squealing sound. also if it makes the squealing sound on mine when raising the 3ph, it only does it for a short bit then raises then done. won't do it again until the bush hogging cycle happens again. it has 80 hrs on it and i did the first 50 hrs change to the book= only engine oil/filter, and hst filter, no strainer or sudt2 fluid drain and replace. book says to do that at 400 hrs first time:confused2:. any way i was told the new 400 hr change interval instead of 50hr then every 300 hrs after for hyd/trans sudt2 fluid is because kubota has listened to customers and cleaned up their act by cleaning out the factory debris better and havinbg much better tolerances on the pumps/working parts, etc.. any way, i am going to run mine for awhile as is and see if the problem continues. thanks for posting your issue. i will remember it when i do clean the strainer. i am still caught between trusting what kubota says and what i have recently heard, and thinking it is just a new conserve oil thing and deal with the equipment issues it might cause later, or should i just dump all hyd/trans fluid and refil and do both hst/hyd filters and clean the strainer @ 100 hrs and be done with it. sounds like yours is making the squeal in the hydrostat as well as the 3ph. mine is just the 3ph. maybe that gob was causing back building pressure and after so long there it goes,,, into releif squealing, after so much pressure built up. hope your problem is fixed and good luck.
