This portable grinder is powered by a recently rebuilt 525hp Cummins N14 Diesel engine with only approximately 30 hours of use. The grinder itself  only has 1,200 hours of use since it was refurbished in 2020.  This grinder will work great for processing trees, construction/demolition debris, log yard waste, stumps, railroad ties, storm waste and much more.  This unit also comes with several extra parts as well.
