Well! I drained the hydraulic fluid, it was plenty thin enough. filled with diesel, started but the FEL would not operate. Pulled the screen out it was clean. Tomorrow I'll put it back together and put a heater on the remote valve hoping to get it moving so I can get it down in front of the shop from the corral. maybe there is some crud in the quick connects. That would be better than the pump or pump drive shaft.

Not sure how your tractor is plumbed but if its just your FEL then maybe its a stuck Pressure Relief Valve in the FEL valve.

Could be bad, or not properly connected QD's (quick disconnects) too?
Chris, Its a Jinma FEL I don't remember if its a 20 or 30 with the rectanglish Valve Not the one Rob did the break down on.
Rob, Too long no hear! Hope you've been in the pink. QDs: Could be they are the origionals but I haven't opened or connected them recently. Never had one apart. Maybe some junk in one? It was colder today, in the twenties. I'd like to get it down off the hill, another snow and it might be there until spring. It seemed to come on with the cold weather.
Thanks for being there. Richard

I'm with the majority here, the flush probably busted some crud loose and it's lodged somewhere obstructing the flow. Note of caution, the crud that makes it through the loop will eventually hit the suction screen. So make sure you check it again before putting in clean fluid.

How many pumps does your tractor have? I know some have 1 and some have 2. The 2 pump systems I have seen use one pump for remotes, 3 point, and FEL and the other pump just for steering. If you have a 1 pump system it will run everything. If you have a 1 pump system and your 3 point and steering are working then you know its in the FEL valve or lines.

I think if the FEL is only thing affected then it is the pressure relief valve on the FEL valve. Does the 3 point work normally? and does the steering work normally? if so it is the FEL valve. Use the TILT and the RAISE together to get the bucket UP then raise and tilt back to get the bucket off the ground to get it back to the barn.
The valve is simple to work on and probably has some junk that was rinsed loose stuck in there it takes very little to prop open the high pressure relief enough to keep the FEL from moving. I know mine did it. the large cap under the ZL20 dual handle valve covers a small set screw & nut. this lock nut needs to be loosened and then turn the screw, back the screw out 1 full turn and run the tractor trying to raise the fel run up the RPMs to full speed. then turn the valve screw back in that one full turn, and lock it down. re-start tractor and try the FEL again. this might flush out the valve well enough to get it moving. also note that when I switched from the old china oil to hydraulic fluid that my FEL now drops when warm qucikly due to the light oil passing through around the valve spools as the tolerances are much greater for these china valve that most US valves which use thin oil, remember that CHINA specs 30 weight motor oil... and if I put that in durring summer it will stay put when raised on mine...

Greetings, There was no flush the FEL will not move.
This tractor has one pump, good point, I didn't try the 3point, but I will.
Rob mentioned the QDs can they be checked by starting the tractor then turning it off then deprissing the valve with a tool or removing the male attachments from the remote?
Bit of a pain, we have wood to split.
