As I was finishing mowing today the trans started making a humming noise (like it was low on fluid) and the tractor seemed slower, when i checked it out there was fluid slowly dripping near the tank but it wasn't at the low mark yet. I did notice a constant sound as if wasn't vented (glug, glug?) and also the tank did not feel like it is fastened. I haven't checked it out good yet because it is pretty hot but does anyone have a opinion on what might be wrong.
Just a update
I could not find any leaks so I tightened the hose clamps and although they did not feel loose I was able to turn them in easily. I added 1qt of John Deere hydraulic fluid and after 1 1/2 hrs of use nothing leaked.
I don't know why but while the trans was low on fluid the tractor would not free wheel, after I refilled it did free wheel. Hope this helps.
No noise. It was low on fluid (1qt) when I went back the next day so I either made a mistake when I first looked at it or the fluid went down as it cooled.
