When I wrote about Khoke’s grandfather rebuilding a 7-sweep rotary horsepower unit, I wrote briefly about some technical issues we ran into. To this, we got a response from John Brubaker, the community mechanic for the Winchester Mennonite community near Hillsboro, Ohio. John suggested we come to see the five 2-horse treadmills connected to power the silage chopper in the fall.
