Título:

440 front end loader will not raise up or down.

Texto:

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.
