having problems with loader not raising with round bale on it, loader is plumbed in through the filter, new filter, cleaned the screen, new oil. so with the loader
plumbed in there does it run off the same hydraulic pump as the scv's? plugged into the scv's with the same result
 

I agree with matthies that hyd stand-by pressure needs to be checked & set at 2350 psi. Where does frt end loader control valve get it's pressure oil? Does FEL control valve have a closed center plug installed?
 
Are you getting your supply oil at the filter??..It is meant for return oil there, the supply should be picked up at the fitting in front of the brake peddles..Just checking...
 

It's possible the pressure control valve under hood in frt of firewall is blocking pressure to the line that supplies FEL control valve.

Does power steering operate correctly?
 
FEL control valve does have a closed center plug. round bales are no heavier than what i always feed. always worked great until recently. seems like the tilt works good so i changed the hoses around on the control valve but that didn't make any difference
 
Maybe you lost a seal in one of the lift cylinders, try and connect a 3000 psi gauge to one of the scv outlets and start there. Use a hose tip, pipe bushing and a gauge.
 
That's my thought. I had a loader do that. Somebody on another forum had it happen too. Like me,he was sure the problem was in the tractor and had gone through everything. It was a lift cylinder on the loader letting oil pass by.
