I'm imagining by 'tool bar' you might mean a 2 or 3 pt hitch - an arrangement hanging off the rear axle that allows the lifting and lowering of towed implements? I also imagine you extended the cylinders via the belly pump by pulling back on the lift-all control rod that diverts pressure to the belly pump ports and hence to the cylinders attached to them.

Not to belabor basic operations but you didn't mention it, did you push the control rod forward? You need to push it all the way forward - lift it over the pins that are there to serve as stops to hold (not apply) pressure and push the rod until its all the way down. Normally this would also mean the rod is in the position where you started from. If you've done this and the cylinders still won't go down, my guess is that something is stuck.

I don't have experience with old cylinders. If this is a rig that hasn't been worked in a while, there may be more than the usual resistance in the cylinders. Is there an implement attached to the 'tool bar'? With the control rod pushed all the way forward, you may need to stand or step from the trans cover plate onto the ends of the rods to get them to go down.

I've also heard of stops in some of the IH cylinders that are there to set the level of some implements. I think they are attached to the rod. Do you have those on your cyls?

You need to give us a little more information. When you pull the control rod to the belly pump back, does the engine go down in RPM to indicate it's engaging? If you hold the control rod back, do the RPMs then go back up to indicate the relief valve is working? You may want to exercise this cycle (if the RPMs go back down) a few times. Try pulling the control rod all the way out and holding it there till the RPMs reduce, then push the control rod all the way forward to release the pressure. If there's a stuck valve, this _may_ break it loose and the cylinders will go back down.

Add more of what's going on to your post and maybe the old hands can tell you just what it is.
