We have engineered a new advance system for the large track machines. It is a rack and pinion design, replacing the ratchet design formerly used. It provides great ease of operation and is ruggedly built to meet the needs of the biggest jobs and biggest machines. It is now standard on the 500TW, 900TW 1200TW, 700TWA and 1800TW (3”-28”, 300 feet and more). Shown here with the Model 1800TW.
