    I believe its done this from the beginning when I purchased it (300 hrs) but I do believe its getting worse... I've changed fluid and filter just spun filter off, let drain, filled up new filter, spun on, filled unit back up.... still making noise? Is this normal to have a slight whine when pushing ths levers..? Thanks

    Hydros do whine, what makes you question your whine is what i would like to know. Typically i would have concern if you have loss of power during operation. The whine is the sound the system working if you ask me but we making be talking about different sounds. Do a search on you tube for ztr's in operation, compare your sound to the sound via youtube
