Hi. Finally got filters and fluids replaced on it after sitting for 15 years and it started right up! When parked, the 3 point worked, but the PTO did not. Now, the PTO seems to be working fine (although haven't had an implement on it yet), but the 3 point will only occasionally lift. There is not power steering or a front end loader. I've played with the adjustment knob under the seat, doesn't make a difference. Any ideas what is happening or what next step in trouble shooting process should be? Thought about removing and cleaning transmission/hydraulic filter again, but not sure if it that could be problem since PTO is now working..... Thanks in advance!

The hydraulic system has nothing to do with the PTO.
I assume you mean you have NO FEL nor power steering on the tractor. Your statement could mean that you have them but they aren’t working. Please clarify what you mean.
And do you mean the 3PH was recently working or worked 15 years ago when it was parked?
I would look at the hydraulic flow path from the sump to the pump. You should be able to disconnect something to see if fluid is getting to the pump.
If fluid is getting to the pump, then you can remove the outlet hose from the top of the pump and get a few ounces into the pump to prime it. Attach the outlet pipe and see if that fixes it. If not fixed, then remove something on the pump outlet and see if the pump is actually pumping. Actually you can start with that check first to eliminate the first two suggestions!
If you have flow out of the pump, it is probably the three point piston that needs to be repaired. Hone cylinder and replace the o-ring?

Yea like @Russell King said the Hydraulic system has nothing to do with PTO operation on that tractor, it's purely a mechanical system to engage it.
If the screen (and in this case) the filter are plugged it will not let the pump pull fluid.
What fluid did you use?

Tractor does not have power steering or front end loader on it. The 3 point worked fine, but not the PTO when parked 15 yrs ago. Was told that the hydraulic/transmission filter could be clogged, which wouldn't allow the PTO to work. When a new one was installed with new hydraulic/transmission fluid (instead of SAE 80), the PTO began to work again. I don't really understand how it works entirely, but will try to track down some schematics to find the pump.... it looks to me like everything is internal in the case? but will look closer and see if I can make some sense of it. Thanks!

The hydraulic pump is external as is the piping to and from it.
You can find illustrated parts list at the site below or at messicks

Here is the hydraulics for your tractor. Your inlet is on top and the outlet is on the bottom of the pump. So I had that backwards above.
There may be a filter for the hydraulics but there may only be a screen that is shown here. It is internal to the sump but comes out the side of the tractor on the opposite side from the pipe shown above.
If you post some pictures of your tractor we will highlight the items you need to investigate.
Since the tractor hasn’t been used in 15 years, I would suggest that the screen needs attention if you did not clean it yourself when you changed the fluid. You can drain the fluid into clean containers and reuse the new fluid.
What did the fluid look like when you drained it?
