Cub 5252 Transmission whine

Why not contact CUB directly and ask? At least it would protect your warranty to let them know you hear it but the dealer said it's OK in case it's not and causes a bigger problem. They wouldn't be able to hold you responsible by saying you should have stopped using it when you heard the noise. Is the noise only noticible indoors like a garage or shed or is it outside also?
That's a good idea sichows. The noise is very loud, even outside. Everything works fine but it is really unusually loud. The hydro oil is checked via a sightglass and looks fine. I think I will do the question to the cub website though.
I wouldn't know what air sounds like or if it can be purged. This sounds like hydrostatic whine except that its pretty loud and does it constantly, even does it at idle. This is a huge tranny, rear pto and all, so I don't really have anything to compare to.
Yep, thats what it sounds like. When I checked the sightglass tonight I thought I saw some bubbles but it might have been a reflection. Sounds like you're on to something. I'm going to call the dealer in the morning. Think that can harm the transmission? I already have a couple hours on it.

I think it is normal to have some air bubbles in your hydrostat when new. They will eventually purge out. Not sure about your whine, or if that is what is causing it. I had some bubbles in my JD 2210, and had to add fluid here and there the first 10 hours or so (have a FEL, too). Everybody, including dealer said that was normal when new.
All hydrostatic drive trans. have that characteristic high pitched whine. Some more than others. If you suspect some air; running the transission at full pedal speed at operation rpm for several minutes should purge any air. It the park brakes are sticking, this can make the whine worse. But if it does it standing still; probably either air or it is normal operation. Have you check the trans. fluid level according to the operators manual? Low oil level can cause this problem too.
Chief, You're right about all the hydros having this whine and it may just be because this is so much larger of a hydro that the noise is that much louder. The fluid is checked by looking in a little sight glass and I can see fluid when the engine is off but not when the engine is on. I think thats normal.
Chief, Question about your 4410, does the same lift handle control both the 3pt hitch and the belly mower? If so, is there any way to lock the mower up while using the 3pt? My cub is set up so that the lift handle controls both, which seems to mean that if I wanted to use a 3pt blade, for instance, I would have to remove the belly mower.
I have 2 pull knobs for the pto's. Unforturnately if the mid pto is engaged the rear pto turns as well. On mine to operate the mid pto; you must pull the mid pto knob 1st and then the rear pto knob to engage. I don't know why they designed it like that but it has not been a problem for me yet. I would prefer separate pto engagement.
