2320 buzzing?

[maximus1277]

My 2320 with 45 hours started to emit a strange buzzing/squealing sound when at idle... It is a gear model so HST is not the cause. The sound reminds me of old cars with AC kicking in or power steering buzzing when wheels are turned to the max, but not as high in pitch. The noise comes on and goes away after a few seconds... But the it comes back again. All fluids are fine, the tractor works fine but this sound is noticeable. Any suggestions?

Sounds like hydraulic bypass. Even if you aren't running an HST, you still have all the rest of the hydraulic stuff to pressurize.

My B2320 does the same thing (although it's HST). The noise goes away after the hydraulic fluid is warmed up, does yours? I would have made the dealer aware of it otherwise...
