I got my sickle bar setup and working this morning, it cuts but makes a racket. The pitman is not lined up straight with the bar. I know the sickle bar is supposed to have some "lead" to it while sitting so it will be straight when mowing. How do I pull it ahead more? The drag bar is a set length. It appears to have been welded so I am not sure if they made it longer or not. Other than that, the clackity clack is great! 8)
