440 front end loader will not raise up or down.
My 440 loader on my JD 870 tractor suddenly stopped going up or down. The cylinders are trying because it will move about 1 inch. I checked and added fluid but still doesn’t work. The John Deere store said it is not necessary to bleed the lines. What else should I look at.
Is this a good question?
Internal seals are bypassing fluid pressure, time for a rebuild.
