I have at last got 1971 8011, very straight tractor everything about the tractor is very much like a tractor that is much newer , even the seat is still working right , the only thing I have found to not work right is the pto I used it to make hay and when on the turner would start off ok but after some time start losing speed, the same happens when put on a slurry tanker fill the first load or 2 right and the next time turn over the pto slowly, looks to be the O rings what do you guys think
