My 400 John Deere mower has a loud whining in the hydraulics A metal line going to the back of the mower, I think it is going to the 3 point hitch area, has a vibration that you can feel very good when it makes the noise. I can move the blade up and down lever and it will stop. But it starts right back. is full of fluid. Anyone had this trouble? I also have this mower and another just like it that doesnt run but I have all the parts to make it run. Motor is apart on mower #2. Would sell them if anyone near Kentucky is interested. Like to know what the whining noise is. The mower mows excelent. Just noisy when it does what I described above.
