After a successful trial period by milling machine contractors using 14- and 16-inch bolt-on Tufpads Hightop track pads, BLS Enterprises, Inc. introduces 10- and 12-inch versions of the pads designed to last 25- to 50-percent longer than standard poly bolt-on track pads. The 14-inch Hightop, originally designed for the massive Wirtgen W 2200 milling machine, has been used on Roadtec, Caterpillar and other Wirtgen models. The new 10-inch pad can be used on the Roadtec RX-400 and Wirtgen W 1200, W 1900 and W 120 milling machines; the 12-inch variety is for the Roadtec RX-500, Wirtgen W 2000 and Volvo MT2000 machine models.
