Super 55 3 point hydraulic breakdown

Hello everybody, first post to the forum. Ive always come to the site to look over information posted while we have been restoring our super 55 or for any kind of breakdown information i can find. However by my own mistake I have caused a problem. Long story short we (dad and myself) completely rebuilt our 1955 super 55 from the ground up. I can go over a list of everything done to it and probably come up with some pictures if you guys would like to see, but here I am with the problem at hand.

While augering in post holes I either didnt get the auger pulled out of the hole when i traveled forward to the next location or the 3 point actually quit right there and it fell back down with the auger back in to the hole. I'm not going to lie and say it wasn't me, I was getting in a rhythm and should have been paying better attention to what i was doing but here we are. The 3 point arms will no longer raise, when i traveled forward it pulled the 3 point arms down to their lowest position against the will of the cylinder inside the hydraulic unit that runs the arms. When we had the hydraulic unit off during the rebuild we had actually taken it apart a bit for cleaning and not to mention replace the gaskets between the hyd unit and pan and then the pan and the transmission. I know there is that 3 point arm cylinder in there that actually makes the arms either go up or down based on the position of the hand lever. Could it have actually just destroyed the seals on that cylinder and now just lets oil flow one way or the other in the cylinder? Could it have just smoked the pump? My understanding from the shop manuals is that Hydraulic pump runs non stop on this tractor as long as the engine is running - it just keeps the oil circulating. ( Note on the pump, while im rereading this before posting, is that i can move the auxiliary hydraulics lever and can hear the pump actually running).

I can just pick up the 3 point arms by hand and they just fall, there is no resistance to them either being pulled up or going back down. Suggestions?

Thank you for reading this and thanks to the moderators and site creators for an impressive website.
 
Let us start all over. Does the tractor have a valve to run a remote cylinder bolted to the side of the hydraulic housing? If so does the remote cylinder work?

Yes, it does have a valve on the right side of it. I do not currently have a cylinder laying around to try it on but when i do actuate the control i can hear to pump kick on and work like it is sending oil to the valve.
 
If it makes you feel any better, something was wrong with the 3pt system already.

Remember that 3pt system is designed for plowing. It is designed to stop the tractor in its tracks if the plow pulls too hard. That's with the tractor running wide open, with your foot off the clutch which I can only expect was not the case here.

Of course if you were running wide open with the tractor weighted to the nines and just dumped the clutch, I could be completely wrong...

What you did, didn't break anything. It was broken already. This added stress just finished it off. The 3pt should have held position and either bent the auger or made the wheels spin.
