Jerry if the seals went out of the tilt cylinder I should still have up/down boom? I made a few calls and found out that the guy that had it before the guy I bought it from took it in, had it serviced, then was using it and the bucket just fell to the ground, nothing from that point except forward/reverse and steering. I pulled the plug and looked at the fluid, it is super clean, so I kind of want to believe this story. So now I am thinking one of 2 things, air lock in the pump or control valve. I have had irrigation pumps do this, get them going didn't set the pickup deep enough in the water and the pump sucks the level down to where it is bring in air, next thing you know no water pressure but everything appears to correct. Or the hydro pump just quit. I haven't seen a pump just quit, I have seen them get slow, and weak over time, until one day you just go to town and buy a new pump because it would be faster and easier to feed the cows by hand then with the loader on the tractor. Anyway is there any way to bleed the hydro system on one of these machines?</p></blockquote><p></p>
