NE South Dakota Clark, SD | If your front end is heavy enough, autosteer works fine on 2wd. If your front end is light, it will struggle to keep as close as it should. I have never put a Smartrax on a 7120,but as along as the hyd systems are the same,that valve should work. They make different valves for open and closed center systems. Also on the closed center side there are Load Sense and Pressure Compensated variants. I do know that the first red Case tractors had a reactive steering system, and that needs some extra plumbing. I am not sure on the boxcar magnums. |
