The M81 Big Workhorse from MyTana Mfg. Company is a mainline machine for those who are comfortable with a sled-style machine and like the option of easily adding additional reels of cable for runs of more than 125 feet. It has a quiet capacitor start motor that allows the contractor to listen to the cable as it works its way down the pipe, and helps the operator react quickly when cable torque starts to build. It is suitable for 3- to 10-inch sewer mainlines and is available with either 11/16- or 3/4-inch sewer cable, up to 125 feet long. The gearbox drive mechanism is capable of driving up to 400 feet of cable. Reels can be added or changed in seconds. The optional automatic feed retriever saves wear and tear on the operator’s arms and shoulders. It comes with a full set of 2- to 6-inch blades and a set of replacement blades. The open-spoke reel with cover is standard, with a molded hard plastic reel available. 800/328-8170; www.mytana.com.
