I'm not sure a question about a New Holland is appropriate for the Ford Forum but I am at wit's end and need help/suggestions. I have a TD 5050,4 wheel drive with a hydraulic problem. While baling with a Claas round baler, the back lift stopped opening fully was sluggish and the motor lugged down. At the same time the front tires seemed to become possessed and, as soon as the steering wheel was moved, the tires would continue turning on their own until fully turned. This was in both directions. The New Holland dealer suggested changing the filter and fluid. I did this and found small metal particles in the fluid and on the magnets of the drain plugs but nothing that couldn't be related to the brakes. After changing the fluid and filter I hooked it back up to a batwing mower to test it. Same symptoms occurred but during the test the main hydraulic line (metal) that runs to the steering column behind dash ruptured at the copper washer under the bolt. It seems like there is still good pressure but in the wrong places. Too much at the steering and too little at the lift. Any help would certainly be well received I can assure you. Thanks. kirkmc
