We have a TC35D w/757c BH and 16la FEL. The problem we have is no pressure to the power beyond. BH was working and we removed it to use the 3PT, once we figured how to hook up the power beyond the 3pt worked fine. Used the 3pt with a drag blade several days with no problems, took a break one day and set the blade down, when I came back tried to rise the blade and it wouldn't come up. After some work we were able to put BH back on and still no power. Any idears, there is flow but no pressure. We are the 3rd owners of this tractor, the 2nd owner never had the BH off.
