When my machine went down in a field I called and reached Ron right away. within a minute he knew the problem. He had the part I needed and explained precisely how to do it. I was able to get back up and running the same day. Chip A Stump thanks you!

Ron goes out of his way to be helpful, and is the only Deutz dealer in the Country that actually will loan out specialized tools and then will walk you thru doing the repair yourself! Highly Recommended!
