Tractor Repair: Stuck in neutral

Question
I have a massey ferguson 1660 struck I'm neutral.. All shifters are free.. But the dash screen reads   N and won't show a rabbit, turtle or snail and wrong move.. I need trouble siting answers

Answer
This is a question that will demand a lot of testing on your part, I'm afraid.....first, it COULD be a bad sensor. However, it is probably either low hydraulic pressure, OR you have a bad clutch pack. Start with the sensors and electronics FIRST. That is where the problem is, in my opinion.
