Clay Rural Water System

We have been looking for a cost-effective, efficient way to exercise our pipeline valves. We have found that exercising larger valves is time consuming and a real chore for our operators. We demoed a hitch-mounted Spin Doctor and decided it was the right tool for us. As most of our valves are located in ditches and fields, we decided we needed something that would give us good off-road capabilities. HURCO had told us that it was a common practice to mount the Spin Doctor on an ATV, so we went ahead and took that approach. So far the combination has worked very well for us. Our valves are spread out over a large area and the ATV allows us to move between valves quickly. the flexibility of the Spin Doctor allows us to reach over fences and get into tight spots.
