I have changed mine several times without any issues. Try working the lever a few times .

6QTS. or 4Gal. 303. ? And did you remove and clean the Filter? Mine was pretty much clogged when I changed it for the first time. I replaced it though...

Does the tractor have a loader on it? If so, does the loader work?

I did clean the screen, 4 gals of Fluid,,have worked the handle several times,,chcked the linkage under the seat and it all appears to be working

As in Connected and moving properly. Now functioning? If not you may know this but while your under the seat make sure the round knob is turned fully counter clockwise. Which is open. All the way in is closed which puts a safety lock on the 3PT..

Glad it's working for you now. Self healing is best. I have no idea why it would quit like that. My guess is the input to the hydraulic pump got air-locked somehow....but it's never happened to me. Did you loosen a line or do anything else when changing the oil?

I agree it got some air most likely. But I guess it just worked it's way out. They are designed not to have to be bled and are basically self bleeding.
