Southland Tool provides positive mechanical cleaning with a 6.5 hp power drive that rotates sewer rods and tools of either 5/16- or 3/8-inch diameter in lengths up to 600 feet. This unit has instant reverse transmission and Speed Chuck to provide positive engagement with a string of rods. The frame is powder coated, and shafts and covers are zinc plated to provide corrosion protection. A complete rod outfit with trailer, rods and tools can be a solution for sewer lines from 4 to 15 inches. Many cities employ these units for emergencies or where a jetter cannot access. They are available with Honda engines as an option, pneumatic tires for over terrain use and in four-wheel models. Just engage the rods and push the machine forward for positive unblocking of sewer lines. 714-632-8198; www.southlandtool.com.
