The little city i worked part time at had one, 5' behind a little JD hydro tractor. It was a Roadrunner brand. The good part was it was adjustable for depth so as the blades wore you could drop them down easily. It didn't have teeth but had the serrated rock cutting replaceable grader blade for the front of the 2 blades. Many of the city streets here don't have a lot of gravel and there are some big round rock barely under the surface. I had to dig some out so the grader didn't hit them and bounce up. I really liked it, it moves the gravel to the left and puts a crown in the road. They had a old road grader but this was so much faster and easier. Made a very smooth road and looked like it had fresh gravel added when done. We ran it every other week when the road was wet. I could do all the roads in a 1/2 day, grader took most of 2 days and was not near as good. We could keep the roads pot hole free much cheaper. Grader used a lot of fuel and maintenance....James
