I am new at using hydr. cylinders and a dummy anyway. I need to know why I can't make a cylinder work, the tractor works with other cylinders but not this one. It is a new cylinder that I got from an auction sale. I need for it to work 2 ways but it won't. It went out once and hasn't moved since no matter what I do. There are two threaded holes at the bottom and one at the top. I'm am beginning to believe it is a one way cylinder, but I don't know for sure. Any ideas

You may find the hydraulic control, and ajacent lines, are single acting and do not supply pressure return.

Unhook the cylinder from the machine, drain the oil out of it, and and take it to the shop where you can use an air line to see what all the holes do. Put air to the top hole and see if the cylinder retracts back in. If it does is there air leaking out from either of the bottom holes? It may retract simply because of the surface area involved and the sealing effect of the other seal basically though if the air escapes from the bottom either the seals are bad or it's designed to be single acting only. Put air in the bottom holes and again see what happens. if air immediately shoots out the other bottom hole you know their connected so plug one of them and proceed to see if the rod extends. If so then check for air leaking around the top hole which would again indicate either bad seals or it was a single acting cylinder designed to power retract. basically extend and reteract the cylinder from each hole while checking the others for leakage that would indicate bad or nonexistant seals. God luck.

How do you have your hoses connected to the cylinder? One at the bottom and one at the top? What did you do with the third hole?

I tried both ways. That is with one at the top and one at the bottom than I tried it with both at the bottom.

The two at the bottom are connected to the same space. There are two just because one will work out to be more convenient for plumbing than the other. The second one at the bottom needs a plug.

The return line should go to the connection on the plate at the piston rod end and pressure on that hose should pull the piston rod in.

Its possible but less likely that there are two on the piston rod end, and one may have a vent for having used the cylinder single acting. You need a plug in place of the vent if that's the case.
