2014 Calmer Ag Research Data

"I run a JD 643 and we ran standard Deere rolls last year and those rolls were pathetic compared to your Calmer rolls! We've only been through 15 acres and I had to call and tell you how amazing they are! I have neighbors who run chopping heads and they don't even compare to your rolls. We're really happy!"
