Hydraulic ideas?

I know I touched on this before but I kinda let it go with deer season coming to an end. Spent a lot of time in the timber. But now that snow is predicted, anyone have any idea why my hydraulics would be so slow to respond when I bring the lever up to raise the back blade? Once it starts coming up, it seems to come up normal speed. It's just everytime I try to raise it, it takes anywhere from 5 to 15 seconds to start up travel. I loosened the allen head plug on the pump and no air, fluid only. Could the friction nut on the lever have anything to do with it? It seems loose at the bottom portion of travel but then stiffens up as the handle is raised? The hydraulic fluid level is full. Also, seems to hold up position even when tractor is off. It's been about 1/2 hour now with blade up and no drifting down if that is any help. Any ideas? Thanks! Tom
 
It could be your unloading valve starting to stick. I have a 801 tractor that I have to give it a quick throttle to start it working. Its worse in colder weather. I didnt see your model number.
 
Let the oil warm a little and bump the throttle a little, if it lifts then its probably the unload valve Oring. Use only the OEM Ford oring. Before you break into it I would pick up somethimng heavy and see how long it holds position before it corrects itself. Everytime it self corrects it puts more wear on parts. If it corrects too much, I would put a new oring and wiper on the lift piston while in there.
