2 years ago we decided it was about time to replace the whole cutter bar on our haybine. We had been having problems with the piece that connects the cutter bar to the arm on the wobble box. It broke one day so I welded it back together. It lasted a little while then broke again. After repeating this a couple more time and 1 or 2 new ones we discovered it was the skid plate that sits underneath it that was the issue, it was bent and hitting the cutter bar. Replaced it. It still broke. Just took longer. Welded it and finished out last year. Started this year and all was good till today when it broke the new one that had been in there a month. I am getting really tired of taking it apart and welding it. Can anybody give me an idea on where to look for an answer to this mystery?
