24-inch Stump in 3 Minutes by Home Built 65 hp Grinding Machine

We are running the Wisconsin V465 with New River Revolution HD Commercial 26" cutter wheel. I put this machine together in my workshop over the last two months. It is belt driven and uses a manually engaged spring tensioner to activate the cutter wheel.

interesting BEAST of a machine ... I was looking for a mini-skid mounted grinder but they seem pretty rinky dink
