I have a MF 271 and pulled it into the barn a week or so ago and everything was fine. Yesterday I went to use it and the 3-point arms won't lift. The front end loader works fine as does the aux hydraulics. I had changed the hyd fluids about a month ago and found some slime in the linkage strainer which I cleaned. Thinking maybe something had plugged it again I drained and pulled the filter again. The stainer is clean as a whistle. I am kind of at a loss as to what to look at next. Any ideas? Thanks

If it has draft sensing, make sure you adjust/set it or it will not allow the 3pt to raise.

Some tractors are equipped with a combining valve - a combining valve will direct oil flow that normally goes to the 3 pt and send it to the loader and rear remotes to increase loader speed. If that lever is in combined flow position the 3 pt won't work. Look for a lever sort of located on the backside of your legs and sort of under the seat.

Thanks guys. My draft control lever had seized to my postion lever but had never caused a problem before. I kept saying I was going to take the assembly apart and unstick them. I guess the draft lever must have gotten just enough off to make it quit working. A little fire wrench work and some penetrating oil has it going again.
