The DM175 is used for 3-inch to 10-inch diameter main lines; commercial, residential, overhead and wall clean-outs, floor drains; heavy grease or tree roots. American made for durability. The upright design of the DM175’s welded steel unibody frame allows for service technicians to operate the machine in either a vertical or horizontal position. Removable leg supports are standard. A steel head bearing holds the reel in place and allows for a quick reel change with convenient swing bolts. The built-in tool box gives you easy access to specific tools. A winch hook at the top of the frame makes it easy to lift the machine.
