I have a 1962 4000 Industrial model. The 3-pt lift will go up, although when you lower the lever, it does not go down. It does not have any sort of load on it (the arms are too high to mount anything right now).... and I need to get it down. Any ideas/suggestions?
Also, this tractor has not been used much over the last several years... so, something might be stuck.

Thanks

Most likely the unloading valve (down valve) is stuck closed, or the linkage is loose.
That would be the most common problem. Generally, it's more work getting to what needs fixed than fixing it. If your tractor has a single rear remote valve you may be able to bleed the pressure off there.

The 600 series through the 4 cylinder 4000, the lift is basically the same.
This guy references other videos that might help. So I thought it might be good to post.

I have an update. I worked with it a bit today, and have it going down a bit more. Interesting part is that I have a full range of upward movement from the bottom of the lever upwards - and the arms seem to go higher than normal. So, question: can I unbolt the arms (ref picture), move the arms down some notches, and make that work? It almost looks like a previous owner set the arms up for some reason. Thoughts?

Most can be. Some may have a keyway or alignment spline and not be able. I've done a couple of Ford 8Ns where when I got the tractor the lift arms "bottomed out" near a foot above the ground. It would just let the grader blade I had just touch the ground. I moved them to about 6" above the ground. The hardest part may be getting the arms off the splines depending on how much rust is binding them. Old Fords are notorious for having a missing drawbar. Moving the arms up to a decent drawbar height when bottomed out and adding the aftermarket three point drawbar and stabilizer arms was an inexpensive fix.
