We have always run Deere Auger heads. They brought out a MacDon draper last year for us to demo. We now have a brand new one sitting in the shed waiting for the beans to ripen. We traded in our 635F. The only reason we went with the Macdon over the deere is that we tried it and liked it, and the price was a hair lower. They never brought the deere one out that they were demoing, so we didn't want to jump on it not knowing if we would for sure like it.
