Well I think you are a little low on the 1200 PSI. Will need to check to be sure. Early tractors were 1200. Another thing when you turn the wheels the unit will only develop enough pressure to over come resistance. I also think you have something loose somewhere in the front. Perhaps the puller bolt or maybe the arm to which the tie rods attach as the bolt had a habit of streaching and that caused the arm to work loose. It is finally dry here and we are trying to shell some corn so it may be a few days till I get back with you.
