I picked up a new Exmark ztr the other day and I've put just an hour and a half on the meter but there's still a loud growl from the hydro. It seems to get a little louder going up the ramp and up hills. I thought it would go away, and the dealer doesn't think anything of it but it's driving me crazy. My Husqvarna ztr is as quiet as can be. And I don't hear this noise coming from other crews using Exmark Zs. Is this something that will go away with time, or should I be more persistent...
