I have a Allis Chalmers Tractor (series 160)
the hydralics one day would not work. A friend had fixed it to were it would raise up and down. The delima is that it will not lift what it use to lift. It would lift the front wheels off the ground, the hydralics was so strong. When a implement is attached to the 3-point hitch now, the piece of equipment sets there and jumps up and down and range of 3/4". I have tried adjusting the jumping out of it with the flow control valves under the seat, but you can adjust so far. Also the hydralics system after running for a while, they will not lift the equipment you have attached to the 3-point hitch, (bush hog, 3-bottom breaking plow, box blade). Please give me some ideas on what might be the problem.
