Kubota 7100 hydraulics drop

B-i-l has a '77 Kubota 7100. It has 3-point, not position, but you hold the lever until the the arms get to where you want them, then let go of the lever.
Well, last year the 3-point dropped, and dropped pretty fast. It would hold up if you raised the 3-poit all the way up, but any othere position, & the arms would drop in a couple of minutes.
This year is worse. Arms drop even when all the way up. Drop even faster. Only time they held a little is when I put some real weight on them, 5 heavy wet bales on a pallet. Then it dropped much slower, but still dropped.
So, my b-i-l has the parts diagram book, & I would love to experiment on this non-critical tractor to learn about hydraulic systems. What's wrong, what do I check, what do I open?
Type slowly so I can understand... ;) I can rebuild my combine in the dark, I have a clue on engines, but I'm a dummy on hydraulics.
