I'll take that bet. I have worked in both green and silver shops. In neither case were we able to get Cummins to respond to urgent problems. To them they all rate the same. Good luck getting your local cummins guy out at midnight to work on your r75. As for them being expert......most cummings tech are just real good parts changers. I have had to fix a lot of problems created by so called "engine guys". Ask the farmer who spent around $6,000 on low HP problems with an engine mechanic only to learn the main drive belt wasnt adjusted right. Ya buddy, get them specialist right out there. They cant get parts any faster than your dealer, they dont understand farming in general, and they sure dont know any thing about how that engine relates to your equipment. I have been around for all the Agco changes from the end of the west allis engines till now. I am all for an engine that Agco owns. Before this my choice was Cat......but this aint bad either. vstk
