I have a jd 4320 with a 400x loader. I致e only had the tractor for a few months so I don稚 have a good baseline however any other tractor I have ever used if you can lift something with the bucket you can curl it. I知 not able to do that. Yesterday I loaded my 6 disc and 6 mx6 bush hog on my trailer. Both of them I picked up by putting the bucket against the 3pt and running a chain from the hook on the top of the bucket under where the top link goes and back to the top of the bucket. With it hooked up like this after I lift it wouldn稚 curl. However if I curled first it would hold position as I lifted.

Last night I unplugged both curl hoses and hooked up a pressure gauge. The pressure release is tripping at 2475, same as the lift circuit and rear remotes, so that seams correct. What should I look at next?

It is possible you have one or more hoses going from the steel lines to the cylinders, going bad, on the inside. As they age they can break down.
