The hydraulic noise ( Whining ) is so loud when the tractor is started up and remains that way when its hot or cold, even my neighbors tell me there is something wrong with it. The noise just started at 28hrs. And is embarrassing because I had a kubota that never made hat noise. When I looked at the tractor and drove one at the dealer ship it never made that noise and if it did I never would have bought it. Does anyone have any idea on what is wrong before I get the run around from the dealer.
