ABSTRACT:
A sewer pipeline root cutting apparatus having entirely internal fluid passageways and interchangeable skids. A hydraulically driven motor drives a shaft for attachment of a cutting tool at one end, and has a thrusting nozzle connecting a high pressure hose at the other end. The system is arranged so that the high pressure thrusting nozzle connector holds the interchangeable skid assemblies on the hydraulic motor housing in use. The interchangeable skid assemblies are easily exchanged by simply removing the thruster nozzle and replacing the skid assembly, allowing the pipeline cleaner to be adapted to pipelines only slightly larger than the apparatus up to some of the largest sewer lines.
