Hello, I operate a Kubota B6100 for my Mother on her hillside property. While warming up the engine a couple of days ago, I heard a high pitched wining sound from under my seat where the gear box is. The unit was running fine and did up until I shut it down. I checked the gear oil's dip stick and also under the cap. The fluid was "frothy" in a kind of a light beige color. I don't remember seeing that way before. Does anyone have any suggestions what the issue may be? I plan of changing the fluid on that before operating it again.
