Miller Pro 75T Stump Grinder Arboristsite.com
May 18, 2015 Texas. May 17, 2015. #1. I purchased a Miller Pro 75T stump grinder. It needed some work as it was poorly maintained, but everything major was sound. I was a little frustrated to find out that Miller sold to a new company on March 1st.grinding machine for flex. They are changing the design, and don't have the parts list for the old design.
