While working, suddenly lost hydraulic pressure to rear remote and 3-pt lift stopped working. No noises and plenty of fluid............any suggestions where to start?? thanks

My TN75 did same thing a couple weeks ago. Thought one of the pumps went out but after talking about this issue with a dealer I bleed the hydraulics and all is ok now. It turned out to be air got in the system some how. Easy to do and just takes a few minutes. I would definitely give it a try, doesn't cost anything. If you need directions let me know.

Update: I had looked on several discussion forums and came across one describing a similar problem, but with a different make tractor. Their solution was to park the tractor nose down on a steep grade for a couple of days and let gravity do the work. I had plans for the weekend that didn't include the tractor, so that's what I did. Sure enough, today I started it up, actuated the remote and 3-pt, and everything works fine.

Recalling what I did a few minutes before it stopped working, I was mowing on a steep tank dam; I guess it was steep enough to vent air into the hydraulic return.
