A few months ago I was mowing swamp grass around 12 ft tall. Worked great until the pitman arm broke, never hit anything, it just broke while I was mowing the tall grass. I bought a replacement pitman arm at Tractor Supply and thought I was good to go. Tonight I decided to put the new pitman arm on but something is not right. The pitman arm does not line up with the blade. Nothing appears to be bent. I thought that maybe the safety trip mechanism needed to be reset but that was not the issue either. Any suggestions? The pto turns free as well as the pulley the belt is around. Me and my father stared at this thing for 30 minutes and nothing appear to be bent or out of place.
