So, this morning I took my tractor and discs to my field for some work. When I got there the discs would not go down. I tried everything. Tractor on and off. Hydraulics on and off and position control would not operate. So, I picked rocks for 45 minutes until the three point and disc leaked down. I left the hydraulics off and used it that way until I was leaving for camp. I turned the hydraulics on to lift the disc and it worked fine.....BOTH UP AND DOWN!!! Go figure! I get to camp and they would not lower again.
I expect that somewhere I have a valve sticking. I checked the archives and could not get anything there........HELP
