I have a 2011 BX 25 HST that makes noises when going forward or reverse. Changed oil & filter last year when it did the same thing. It seemed to work then. I did this when it had 80hrs and now it has 91hrs. It's cold when this happens. What else can I try. The machine IS kept outdoors.

When you changed the fluid, did you switch to udt2? A lot of folks have been reporting that the udt2 removed most of the noise from the hydrostatic

Yeah the BX whine is a function of the pump and where its laid into the body of the machine,, SUDT 2 a tad pricey will cut down on some of the noise I think it cost me 85 bucks for a 5 gal pail. And a set of ear muffs will cut down on the whine too and you can still hear other noises on the machine.

Like I said Bert,, the whine on the BX is a function of the pump, the ROPs acting like a tuning fork and it's location,, If it stops making a whine,,, then my friend you got a problem :D

I guess my concern is, "Will this harm my tractor?"

NO - it will not harm a thing other than your pocketbook!! But the money you paid for it, will PAY you back in year/hours to come.

Sudt2 is an oil that flows easier when cold, lubricates better, does not break down or lose it's lubricating abilities as fast as standard hydraulic oil. Kubota actually claims a small power increase via this fluid.....
"Improved transmission efficiency through reduction in power loss"

I will be spending them thar bucks soon - and I hope the whine does simmer down a bit.....

Skeets - you are right , hard to hear that whine, when you got earmuffs on, and loud music playing !!!! :D:D ( cant hear the wife either!) :eek:

Skeets, you're wearing the ear muffs wrong, they are supposed to be going over your ears, not your eyes... :rolleyes:
