| If your Deere parts are like new, I would wait until they wear out before you swich them out. Also, I think Deere engineers had a good reason to make three different styles of concaves for the STS that could be switched out in 45 minutes. It would have been much cheaper (and more profitable for Deere) to have one concave for all crops. Kuchar's rasp style threshing elements may be better than Deere's when harvesting wheat that is hard to thresh. | |
