Jetter project
Highway drainage repair and cleaning require the use of a jet rodder to blast through debris to get the water flowing again. Production units are very expensive and found in limited numbers around the state. This D-6W project will construct a rodder utilizing the hydraulic power from their existing John Deere tractor. This will substantially reduce the cost of purchasing a production unit.
