My 3-point hitch stopped working. It would run full up if the selector was past 3, and full down when the lever was below 3. Clearly the feedback wasn't working.
Upon investigation, I found that the rod from the left lift arm to the feedback lever was bent. This, in turn was due to the feedback input shaft seizing. I was able to free it with a few days of penetrating oil squirts and working it back and forth, gradually increasing the range. It now moves by hand.
At any rate, it is not on the lubrication schedule in the owner's manual, and since it is not in view like the pedal pivots, it is easy to overlook. I would advise people to take off the cover under the seat and lubricate both sides (input lever side and feedback side) with a medium (30W?? oil) periodically to avoid this problem. Note that the Maintenance manual indicates that the bellville springs on the input side get lubricated with gear oil, but there is no period specified and no mention in the owner's manual.
Note: If either lever is very stiff, don't use extreme force on it. It is part of a walking beam that activates the hydraulic valve, and if you damage the valve or bend the walking beam, it is not an easy repair.
