I had one of those self propelled All Crop combines, it was a beast, not user friendly. I used it one year, and, got a mint Case 600 pulltype. Now that was a great machine, especially in small grain. I used a Melroe pickup, and, pulled it with a 4020, and, i would just eat the grain. I alos liked the big spike tooth cylinder, it made the best straw for beddin my cattle.
