I really hope some of the others will jump in that know more then i but I will try to help.

Do you have an IT service manual for your tractor? (If not this site may sell what you need)

Do you have hydraulic pressure at the outlets?

You can rig up a gauge to a male tip and check the hydraulic pressure by moving one of the outlet spool levers.

If you have NO pressure at the outlets then you need to gravitate towards the pump, pump drive and pump inlet seal.

If you have pressure then you should gravitate towards the control spool for the 3PT and/or possible problem with the piston on the 3PT lift.

Its kind of hard to write down everything that you would need to do but generally your pointed in one direction or the other.

Search the site. Its been a topic many times. I have personally had troubles with the 3 point valve, the sumP screen blocked not allowing any flow, and most recently had the cylinder in the rockshaft housing broke out. Not all the same tractor but my experience with 3 point problems has been enough for me!
