Ditch Witch’s PR100 pipe-bursting system fractures or cuts any type of existing pipe, including clay, PVC, steel, cast iron, and ductile iron. Constructed with heavy-duty, commercial-grade steel, the unit can pull in new pipe of up to 16 inches in diameter with 100 tons of pullback force. For power, the pipe-bursting system uses a 60-horsepower Cummins engine, which is fully enclosed, fully accessible, and, at 83 dBA, not too hard on the ears. Load-sensing hydraulics allows for automatic downshifting when a load is introduced, and higher speeds during makeup and breakout.
