So we have a JD 6715 with a 740 Classic Loader. Basically the boom has split/cracked the entire length of the seem where the box tubing is welded together underneath where the stands get pinned up. I'm sorry I don't have any pictures, I didn't think to take any while I was at work today. But I was just wondering if anyone has had any problems similar to this. I'm not sure if I'm going to be able to post any pictures either because we are going to try and get the dealership to look at it tomorrow and if that doesn't work out we're sending it off to the welding shop and I'm not working tomorrow so I may not get any pictures before it gets fixed.
